How Dental Regulation Is Recorded in the UK, and What the GDC Says About Other Countries

What does the GDC say it cannot guarantee about regulators in other countries?

The General Dental Council sets the limit of its own reach in two sentences on its patient page about going abroad for dental treatment, and the limit is about institutions rather than about clinics or outcomes. The regulator writes: "All dental professionals must be registered with us to work in the UK, and we set the professional standards they must adhere to. We can’t guarantee another organisation like us exists in other countries, or even that the standards will be the same as they are here." Read closely, the thing declined is a guarantee about the existence of a counterpart regulator and about the content of its standards. Nothing in the sentence is a judgement about any dental practice, any city or any country, and the page we fetched does not name Turkey anywhere in its text.

Having stated what it will not vouch for, the regulator converts the limit into two questions a reader can put to one named country instead of to the world. Its wording is: "Dental regulation is likely to vary according to country, so it’s a good idea to do some initial research. Does that country have a professional regulatory body? Is it compulsory for dental professionals to be registered with them?" The second question is the sharper of the two and is easy to skip. A country can have a professional body whose register is voluntary, and where membership is optional, a clinic being a member answers a different question from the one a United Kingdom patient believes they are asking. The regulator does not answer either question for the reader; it tells the reader that the answer varies.

Where such a body does exist, the General Dental Council names what to look for rather than what to conclude: "If there is a regulatory body, you may want to visit their website to find out about the standards they enforce, what qualifications dental professionals must have and who to contact if you have a complaint about your treatment." Three separable artefacts are named in that sentence — enforced standards, required qualifications and a complaints contact — and each of them is either published somewhere a reader can reach or it is not. Describing a lookup is not the same as issuing a verdict, and where the lookup returns nothing, the empty result is itself information the reader has obtained rather than borrowed from us.

Framing for the whole page is set by its opening, and the frame is knowledge of process rather than prediction of outcome. The regulator writes: "Before you commit to travelling abroad for dental treatment, it’s important you are fully aware of what to expect and what risks are involved. You may know how to raise concerns about your dental treatment in the UK, but are you familiar with the process in a foreign country?" The question it puts is about whether the reader knows the complaints route in another jurisdiction, not about whether dental work carried out there will succeed. Under the wording review our methodology page describes, a sentence that would nudge a reader toward treatment or away from it is recast as a description of what is known, so this statement about process knowledge is not translated into one about clinical results.

One sentence on that page is about protection, and its scope is domestic, which is why we quote it with its subject intact. The regulator writes: "Any patient who receives illegal dental treatment is placing themselves at risk as they will not be protected by the rigorous regulatory system that we have in place in the UK." The people described there are patients treated by someone practising unlawfully in the United Kingdom. On the same requirement, the page also states: "To work legally and safely all dental professionals must be registered with the GDC, and only people who are registered with us can legally practise dentistry in the UK." Both sentences describe who may work in the United Kingdom. Neither describes what happens to a patient treated lawfully somewhere else, and reading the first as a comment on treatment abroad would put a claim in the regulator's mouth that its own words do not carry.

What the General Dental Council does supply is a list of questions it tells the reader to ask, and three of them bear directly on the guarantee it has just declined. The list appears on its patient page about going abroad for dental treatment, under the heading Questions to ask, and it includes "Are you regulated by a professional body and are you registered with them?" It also includes "Is the work guaranteed for a certain period of time?" and "Do you have insurance to cover this procedure?" The regulator is handing the reader an interrogation to conduct rather than a conclusion to accept. Where a dental provider cannot answer those three, the absence of an answer is a finding the reader has produced, and it is a finding about one provider rather than about a country.

How is a UK dentist's registration recorded?

Publication of the United Kingdom dental register is a statutory duty, and the General Dental Council says so in its own words on the page describing the registers: "We have a legal duty under the Dentists Act to publish our registers and we do this by providing a complete copy online." Two things follow, and neither is ornamental. The register exists because a statute requires it, so its availability does not depend on the regulator's goodwill; and what is published is described as a complete copy rather than a selection or a summary. A reader looking up a dentist is therefore consulting the primary record itself, not a directory that somebody else compiled from it.

Contents of the complete copy the General Dental Council publishes online are listed by the regulator on its page describing the registers. Under the line "The following information is publicly available on the registers:" it names six items: status, registration number, registrant type, date first registered, date current period of registration from, and qualifications. On how to reach them, the page states: "You can search a specific register by entering either a name, town or any combination of these. Telephone numbers are not part of the public register." A name and a town are usually the two things a patient has after an initial consultation, so the search key matches what the reader is likely to be holding. The excluded field is stated by the regulator rather than inferred by us, and it is a contact detail rather than a professional one.

Coverage of the register — which roles it has to list — is wider than most readers expect, and the General Dental Council enumerates them on its patient page about what to expect from a dental professional: "By law, all dentists, dental nurses, dental technicians, dental hygienists, dental therapists, clinical dental technicians and orthodontic therapists who provide your dental care must be registered with us." Seven registrant titles appear in that sentence, so the population the record covers extends well beyond the person holding the handpiece. What the list is kept for is stated by the regulator too: "We maintain a list of everyone who is registered with the GDC and we would always recommend that patients check that their treatment or advice is being provided by someone who is legally allowed to practice dentistry in the UK." The spelling in that sentence is the regulator's own and is quoted unchanged.

What the register does not record is stated just as plainly, and this is the half that decides how much a lookup can carry. The regulator writes: "We do not record whether a registrant is practising or retired or, if practising, providing treatment on a private or NHS basis or both." It adds: "There is no similar list of dentists who only provide private care." We quote those two sentences and stop, because the sentences sitting between those two in the regulator's own text send readers to NHS Primary Care Trusts, bodies that no longer exist and were abolished more than a decade ago. The quoted sentences are accurate; the paragraph around them is stale, and summarising the paragraph would have published a route to an organisation a reader cannot reach.

Treatment of the register as a record rather than as a product is also written down. The General Dental Council states: "Copies of the registers are not available for sale or for commercial purposes. The information held on our registers is given to us for regulatory purposes and we have legal obligations under the Data Protection Act." On aggregate figures drawn from the same data, it says: "We produce monthly registration reports which give details about professionals on our registers, including the number and types of registrants, and the number of dentists on specialists lists." And on requests to reuse the data, it states: "If you have a specific request relating to use of the data held on the registers, we will be happy to consider it under the Freedom of Information Act." Read together, the three sentences describe a record that is free to search one name at a time, published under a statutory duty, and deliberately not available as a bulk commercial dataset.

Putting the positive and negative halves of the register together is a join we make rather than one the regulator makes, and made that way the record answers a narrow question well and a broad question not at all. It answers whether a named person holds a registration, of what type, since when, and with which qualifications recorded. It does not answer whether that person is currently treating patients, whether they work privately or within the NHS, or anything about the quality of their dental work. Treating a registration as a quality signal would read into the record exactly what the regulator's own sentence says is not kept there.

How is a Turkish clinic's health-tourism authorisation recorded?

A Turkish regulation published in the Official Gazette on 13 July 2017 under issue 30123 named the document a health-tourism clinic had to hold, and this page quotes that text as it was published on that date rather than as the law in force today. The regulation, issued by the Turkish Ministry of Health, carries the title Uluslararası Sağlık Turizmi ve Turistin Sağlığı Hakkında Yönetmelik, and its core requirement, as published, reads: "Uluslararası sağlık turizmi kapsamında faaliyette bulunabilmek için; sağlık tesisinin ve aracı kuruluşun uluslararası sağlık turizmi yetki belgesi alması zorunludur." Our rendering into English is that the text required an international health tourism authorisation certificate, and required it both of the health facility and of the intermediary organisation. Two parties are named in one sentence, so a patient dealing with an agency and a clinic is dealing with two separate authorisations.

Definitions of those two parties sit in the same regulation as published in the Official Gazette, and they describe organisations on different licensing paths. The intermediary is defined, as published, in these terms: "Uluslararası sağlık turizmi aracı kuruluşu: Bakanlıkça, uluslararası sağlık turisti ile beraberindeki refakatçi ve diğer yakınlarına konaklama, ulaşım ve transfer hizmetlerinin sağlanması faaliyetlerini yürütmek üzere yetkilendirilen, 14/9/1972 tarihli ve 1618 sayılı Seyahat Acentaları ve Seyahat Acentaları Birliği Kanunu uyarınca işletme belgesi alan A grubu seyahat acentalarını," The health facility is defined separately: "Uluslararası sağlık turizmi sağlık tesisi: Sağlık tesisi ruhsatına sahip olan ve Bakanlıkça uluslararası sağlık turizmi yetki belgesi verilen kamu, üniversite ve özel sağlık kurum ve kuruluşunu," In our reading, the intermediary must be a travel agency of a particular class licensed under the Turkish travel agencies statute, so the same commercial actor can be a travel business in one legal regime and a health-tourism intermediary in another.

A consequence for operating without the certificate is written into the same article, and so is the rule that binds the two parties together when they work as a pair. The regulation, as published, states: "Yetki belgesi almayanların uluslararası sağlık turizmi faaliyetleri Bakanlıkça durdurulur." On the pairing, it states: "Ancak aracı kuruluş faaliyetlerine ihtiyaç duyulması halinde, Bakanlıkça yetki verilen uluslararası sağlık turizmi aracı kuruluşu ile protokol yapılması zorunludur." Our rendering is that activity without the certificate is halted by the Ministry, and that where an intermediary is used at all, a protocol with an authorised intermediary is compulsory. What the text describes is an administrative permission and its withdrawal, which is not the same object as a measure of clinical quality, and we draw no quality conclusion from it.

Staffing of the health-tourism unit inside an authorised facility is specified rather than left open. The regulation, as published, requires of the unit: "Uluslararası sağlık turizmi biriminde, sorumlu dâhil yabancı dil bilen en az 2 personel istihdam edilir. Yabancı dilin birisinin İngilizce olması zorunludur." On the person put in charge of that unit, one of the listed conditions is: "Türkiye’de iki yılı kamu ya da özel sağlık kuruluşlarında olmak üzere, en az beş yıl meslek icrası yaptığını gösteren belge veya belgelere sahip olmak." Our rendering is that the unit must employ at least two foreign-language speakers including its lead, that one of the languages must be English, and that the person responsible must document a minimum period of professional practice. These are inputs a regulator can inspect, and none of them is an outcome measure.

How the certificate is granted is set out as a documentary stage followed by a physical one. The regulation, as published, ties eligibility to annexed criteria: "Uluslararası sağlık turizmi alanında Bakanlıkça Uluslararası Sağlık Turizmi Yetki Belgesi verilebilmesi için: a) Sağlık tesisinin, EK-1’de yer alan Uluslararası Sağlık Turizmi Sağlık Tesisi Yetkinlik Kriterlerinde belirtilen kriterleri taşıması zorunludur." On the inspection stage, it states: "Yerinde inceleme neticesinde yetkinlik kriterleri bakımından uygunluğuna karar verilen başvurular onbeş iş günü içerisinde Bakanlığa gönderilir." Our rendering is that an application is first examined on the file, then inspected on site by a review team, and only then forwarded to the Ministry within a stated number of working days. A reader can therefore ask a specific clinic which annex it was assessed against.

Record-keeping is also required, and it runs towards the Ministry rather than towards the patient. The regulation, as published, states: "Uluslararası sağlık turizmi sağlık tesisi tarafından, bu Yönetmelik kapsamında sağlık hizmeti verilen kişilerin Bakanlıkça oluşturulan web tabanlı sisteme kaydedilmesi zorunludur." Our reading is that this describes a ministry-side record of people treated under the regime, not a public register a reader can query. The gap is worth naming precisely: we have no verified public endpoint at which a specific health-tourism authorisation can be checked, so a reader can learn the name of the document but cannot yet be told where to verify one.

A currency limit belongs beside each of these quotations, and the limit is ours rather than the source's. What we fetched and quote is the version published in the Official Gazette on 13 July 2017. We tried to obtain the consolidated in-force text and could not: the Turkish consolidated legislation service returned a shell page without article text on each attempt we logged, and the Gazette's own search endpoints returned errors. So we do not write that these sentences are the law in force today. The claim our evidence supports is narrower and is the only one we make: the regulation said this as published on that day.

What did the BDJ review report about regulatory processes?

A peer-reviewed review of how United Kingdom news media reported dental tourism, published in the British Dental Journal in 2025, states what recurred across the articles it examined: "The lack of regulatory processes and absence of access to legal redress or follow-on care was a common concern across the articles." On what the same articles said about who picks the work up afterwards, the review reports: "A few articles described remedial care as being provided by the NHS, while other private providers described actively avoiding the provision of care for people who'd had dentistry abroad because of fear of liability", and it then quotes a practitioner at length. The unit counted here is a newspaper article, not a patient and not a clinic, so the sentence records what was commonly reported rather than a measured rate. The NHS appears in it as a described destination for remedial care.

Where the review touches responsibility for that remedial care, it does so by reporting an earlier position rather than by measuring practice. It writes: "The Department of Health has previously indicated NHS responsibility to provide emergency care, but not remedial care (eg elective revision), for cosmetic procedures provided outside of the UK." A limit travels with that sentence and we state it because the article does: within the review, the claim is built on literature about cosmetic surgery rather than on anything dentistry-specific, and the citation is to that literature. Anyone quoting it is quoting the review's summary of a general position, which is why the source named here is the review itself (DOI 10.1038/s41415-025-8330-2, open access as PMC11870843) and not a health department publication.

What the review actually counted is stated in its own methods, and the numbers are about articles rather than about outcomes: "The search strategy identified 201 newspaper articles related to dental tourism. A total of 131 articles were included in the analysis." The authorship line recorded with the article is Doughty J, Moore D, Ellis M and colleagues, and we read that line from the article record rather than from memory, because a correct journal, a correct volume and a correct sentence can all sit beside an invented author name (DOI 10.1038/s41415-025-8330-2).

One finding in the review runs directly against the reading its subject matter usually attracts, and it is the single most load-bearing sentence for a page about dental implants in Turkey: "Almost all of the articles about post-operative complications were Turkey-centric, primarily because the media were focusing on social media accounts using #TurkeyTeeth, as opposed to Turkey specifically being implicated in providing substandard dentistry." The authors go further about the grouping itself: "The convenience of collectively placing all overseas dentistry within this category should be acknowledged as both unfair and inappropriate, and yet has become a recognised colloquial term in the zeitgeist for what is otherwise a difficult-to-define and complex social phenomenon." Taken at its word, the review is reporting that the concentration of coverage followed a hashtag, and it says so in the same breath as it declines to treat that concentration as evidence about one country's dentistry.

A distinction the review says the reporting failed to draw is worth carrying into any page about dental treatment abroad, including this one. The authors write: "Journalism examined in this study failed to recognise and acknowledge that the phenomenon of dental tourism should be broken into two separate components: 1) dental tourism that promotes access to routine dental care; and 2) dental tourism for purely cosmetic reasons." The split is the review's own instruction about how the subject should be divided before anything is claimed of it, and a page that ignores it ends up describing routine care and cosmetic work with one vocabulary.

Scope is the thing most easily lost when a review like this is quoted, so we write it out. The study examined newspaper reporting, and its findings are findings about that reporting. A concern recorded as common across articles is a fact about what journalists and the professionals they interviewed said, and it is not a measurement of how often patients experienced the thing described. Our methodology page counts journalism as evidence that something is being said rather than as evidence for a fact, which is a different claim and is written differently, so a concern of this kind is reported with its unit attached and is not promoted into a clinical incidence figure. On what should follow, the review states: "Consumers require more guidance to support them in accessing quality dental care outside of the UK and compassion from UK dental professionals if there are post-operative complications arising from dental tourism." The review supplies the sentence; the unit stays with it.

What did the BDA report its members identified, and what does that measure?

The British Dental Association published figures from a survey of dentists about patients who had travelled abroad for dental treatment, and the first thing to read is the denominator rather than the percentages. Its media centre page states the base: "According to a survey of 1000 UK dentists in the UK:" It then narrows that base a line before the headline figures appear: "The appeal of travelling abroad for dental treatment appears to be widespread, with 94% reporting that they had examined patients who had gone on such trips: however, the findings indicate that the lure of a quick fix may carry considerable risks. Of these dentists:" Every figure that follows is therefore a proportion of the narrower group, and every one of them is a dentist's report of what they saw rather than a count of patients who experienced it.

Reading the best-known figures with that denominator attached changes what they say. The British Dental Association media centre page states: "The highest single risk factor identified was failing or failed treatment (86%), closely followed by pain (76%), and poorly executed treatment (72%)." On which treatments were flagged, it states: "86% reported having treated cases that developed problems following treatment abroad. 87% identified crowns as the treatment most likely to require follow-up work, closely followed by implants at 85%." Our reading, marked as ours, is that these are marking rates: they record how many responding dentists identified a category, not how many patients had that outcome. Writing them the other way round would convert a professional survey into an incidence study, which is a different design with a different denominator and a different meaning.

Within the same British Dental Association page the denominator moves again, and the move is not signposted. Having introduced its headline figures with the phrase of these dentists, meaning the subset who had examined returning patients, the page then shifts back to the full respondent group: "93% of all dentists responding identified concerns around continuity of care, 79% were unhappy with the quality of care, 77% mentioned the difficulties associated with seeking redress or making a complaint, while 66% flagged concerns over communications between patients and practitioners." One sentence on the page pairs a percentage with a headcount, which is the only place the two appear together: "Over 40% (346 dentists) said the remedial treatment was provided by the NHS." A reader who carries a figure from one paragraph of that page into another is silently changing the population it describes, and the page does not warn them.

Across two British Dental Association pages the same survey is reported with two different headline figures, and we record the discrepancy rather than choosing between them. The media centre page gives the base as a survey of one thousand United Kingdom dentists and puts the examination figure at ninety-four per cent. The association's news page gives the base differently: "Over 1,000 dentists responded to our survey, and the results are shocking:" and reports the examination figure differently as well: "95% of dentists reported that they have examined patients who have travelled abroad for dental treatment." Both pages are published by the same body about the same survey. We have no basis for declaring one of them the corrected version, so we do not.

One shift between the British Dental Association's own pages is not a rounding difference but a change of population, and it disqualifies one page for one figure. Its media centre page attributes the cost-driver figure to respondents: "Cheaper costs were identified by 98% of all respondents as the lead factor influencing patients' decisions to seek dental care abroad, while almost a third (31%) of those surveyed said that a perception of shorter waiting times was responsible." Its priorities page prints the same number about a different group entirely — "98% of patients are chasing cheaper treatments." — a sentence we reproduce to record the contradiction, not to use the figure. Dentists surveyed and patients treated are not the same population, and that second sentence describes what patients are doing on the strength of a survey that asked dentists. Where a source contradicts itself in that direction, we use the page that names the population it measured and set the other aside.

What is missing from all of it is the survey's method, and the absence is measured rather than assumed. Across the three association pages we fetched and searched, neither a method section nor a statement of the sampling frame, the response rate or any weighting appears; searching the raw text of those pages for the roots of the words method and sample returned nothing. Our methodology page ties how strongly a claim may be worded to the kind of evidence beneath it, and on that scale the denominator here is a declaration rather than a documented figure. The association also publishes a qualitative summary alongside the numbers: "Several dentists reported concerns about over-prepared teeth – where more of a tooth is removed than necessary – as well as ill-fitting crowns and implants that fell out."

What does NHS England's policy say about access after a complication?

NHS England published a policy in 2024 addressing exactly the situation a reader of this page may be worried about, and its central sentence is an entitlement rather than a promise about dental outcomes. The document, Avoidance of doubt: Clinical policy for self-funded dental treatment requiring NHS intervention, was published on 4 November 2024 and states: "Patients who have previously paid for dental treatment privately in the UK or abroad but later require NHS treatment due to a complication or sudden oral health issue are entitled to access NHS dental care for assessment and evaluation to stabilise their condition." The entitlement described is to assessment and evaluation for the purpose of stabilising the patient, and it covers private treatment paid for within the United Kingdom as well as abroad.

Scope of the document is stated by the document itself in its opening line, and the scope is narrower than the phrase self-funded treatment might suggest on its own: "This note sets guidelines for when it is appropriate to provide NHS dental care after patients have received self-funded dental treatments, including privately funded non-NHS care within and outside of the UK, in cases where patients have acute presentations or complications." Two qualifiers in that sentence do a great deal of work. The situations covered are acute presentations or complications, and the care in question is NHS dental care provided after the privately funded course has already happened. Nothing in the sentence describes elective work that a patient simply prefers to have done on the NHS instead, and the phrase within and outside of the UK puts privately funded treatment bought at home and privately funded treatment bought abroad in the same category rather than in two.

Limits arrive immediately after the entitlement, in the policy's own words rather than in ours. It states: "Any treatment beyond stabilisation will be assessed based on complexity and need and should be provided at the appropriate care setting, subject to existing NHS acceptance criteria as laid out in The National Health Service (General Dental Services Contracts) Regulations 2005". It then states the limit that matters most to anyone hoping the NHS will reproduce privately funded cosmetic work: "Please note that self-funded care that the NHS would not routinely fund would not usually be offered or replaced once stabilisation has been achieved." Read beside the entitlement, the policy separates two things that are easy to blur — stabilising a patient who presents with a problem, and replacing the treatment that produced it.

On eligibility itself the policy is unambiguous, and this is the sentence that answers the question most often asked in the form of a fear about being turned away. It states: "Where a patient has received their care previously does not impact on their eligibility for NHS care in the future." On the principle underneath that, it states: "The NHS will provide the treatment necessary to secure and maintain the patient’s oral health." Neither sentence names a country, and the document we fetched does not mention Turkey anywhere in its text; the operative fact in the policy is that the earlier care was self-funded, not where it was carried out.

Where the policy expects the patient to start is also written down, and it is not the NHS. It states: "It is expected that patients would initially seek support from their self-funded dental care provider, who should be responsible for any post-treatment clinical issues within a reasonable timeframe." On further work beyond stabilisation, it states: "Should the patient request/require further reparative or reconstructive elective care, the provision of care and choice of care setting would be subject to NHS acceptance criteria with reference to the complexity of need." Our reading, marked as ours, is that the document describes a sequence rather than a right of substitution: the provider who carried out the treatment is expected to deal with its consequences first, and NHS involvement beyond stabilisation is governed by the same acceptance criteria that apply to everyone else. A patient who cannot return to the original provider is not excluded by that sentence, but the sentence does place the first expectation somewhere other than the NHS.

What is published about complication rates?

Peer-reviewed reviews do report figures for the two commonest inflammatory complications around dental implants, and neither of the two quoted here reports them by the country in which treatment was carried out. Under the sourcing order our methodology page sets out, the primary figure comes from a review by Galarraga-Vinueza ME, Pagni S, Finkelman M, Schoenbaum T and Chambrone L in the Journal of Periodontology (PMID 40489307, DOI 10.1002/JPER.24-0154), which reports: "Prevalence rates at the patient level for peri-implant mucositis and peri-implantitis were 46% (95% confidence interval [CI], 41-51) and 21% (95% CI, 17-24), respectively." The authors of that review are named here from the article record rather than from recall.

What that figure is, and what it is not, decides whether it can be quoted honestly at all. A prevalence at patient level is the share of people found to have the condition when a population is examined at a point in time. It is not a statement that a given share of people who receive an implant will go on to develop peri-implantitis, and it carries no follow-up period of its own. Rewriting the number as a per-patient risk of a future event would change the study design behind it while keeping the digits intact, which is the most available distortion on this subject (PMID 40489307).

A second review approaches complications from a different direction and finds an association with the shape of the restoration rather than with anything about where it was placed. Atieh MA, Shah M, Ameen M, Tawse-Smith A and Alsabeeha NHM, in Clinical Implant Dentistry and Related Research (PMID 37183357, DOI 10.1111/cid.13214), report: "In terms of emergence profile, implant restorations with convex profile had significantly higher rate of peri-implantitis (57.8%) compared to implant restorations with concave or straight profile (21.3%) (risk ratio 2.32; 95% CI 1.12-4.82; p = 0.02)." Its base is four included studies, which is a narrow foundation for a ratio of that size, and the comparison it makes is between restoration profiles.

What is missing from the published record is as relevant as what is in it, and the limit of our own searching belongs beside it. Neither figure quoted in this section is broken down by the country in which the implant was placed, and no source quoted anywhere on this page reports one that way. Whether some other published study does is a question we did not put to a search, so what stands here is the state of the material we quote rather than a demonstrated absence. Either way this page does not manufacture a country figure by attaching a general one to a country name, and we make no claim that such a figure would come out higher or lower than the two this page quotes.

Neither review supports a country-level reading, and saying so is not modesty but accuracy. The first counts people examined in the studies it pooled; the second counts implant restorations grouped by emergence profile. Neither reports outcomes by the country in which treatment was carried out, neither compares prices, and neither examines dental tourism. A page that placed either figure beside the word Turkey and left the juxtaposition to do the arguing would be making a claim that its own sources decline to make, and the count our evidence audit page describes would record a claim built that way as unsourced.

Independence between the two was checked on one leg rather than assumed across all of them, and the leg we checked is the author line. Five survival and complication papers can share a senior author and read as five confirmations of one another; reading the author lines is what turns that appearance back into one source. The order the rule sets out is author line first, then institution, then citation between the papers, then a shared ancestor such as a guideline both rest on. The peri-implantitis prevalence review and the emergence-profile review carry different author lines with no name common to both, which is why they are counted here as two rather than one. Their institutional bases were not compared and their citation lists were not read, so those legs are unmeasured rather than clear and are not offered here as checks we ran (PMID 40489307, PMID 37183357).

What this page does not say

Nothing on this page answers whether dental implants in Turkey are safe, and the omission is deliberate rather than accidental. Our editorial standards page rules out publishing an accusation we cannot support however well it would perform, and a verdict about a country assembled from statements institutions made about institutions would be one. Every source quoted on this page describes an institution, a record or a general population rather than dentistry in one country: a regulator describing the limits of its own reach, a register describing what it records, a Turkish regulation describing a licensing regime, a policy describing entitlement to NHS care, a peer-reviewed review of how newspapers covered the subject, a professional association reporting what its members said they had seen, and two reviews describing complications without reference to any country. None of them uses the words safe or unsafe about treatment abroad, and neither do we.

Combining those sources into a conclusion none of them states is the specific move this page refuses to make, and it is worth naming because it is so easy to make. A regulator saying it cannot vouch for another country's regulatory architecture, plus a review reporting that regulation was a common concern in newspaper articles, plus a prevalence figure from a study that never asked where treatment happened, do not add up to a fourth sentence about Turkish dental clinics. Each of the three says what it says. The sum of them is not a finding, and we do not present it as one.

Three things we could not measure are recorded here rather than filled in. We have no verified public endpoint at which a specific Turkish health-tourism authorisation can be checked, so we can name the document but cannot tell a reader where to verify one. We could not retrieve the consolidated in-force version of the Turkish regulation, so our quotations are bound to the version published in the Official Gazette on 13 July 2017 and are written that way throughout. And the professional survey quoted on this page publishes no method section, so its denominator remains a declaration.

Discipline about attribution is the other thing this page tries to hold, and it has a failure mode we have already met. A journal name, a volume, a digital object identifier and a quoted sentence can all be correct while the author line beside them is invented, and a check that verifies the sentence will not catch it. Author lines on this page were therefore read from the article records themselves. Where a figure or an attribution here later proves wrong, the change is logged on our corrections page instead of being quietly edited away.

Questions this page leaves open are worth listing, because a reader who came here looking for a verdict deserves to know which parts of the question remain unanswered rather than merely unstated. We cannot tell a reader whether a particular clinic holds a current Turkish health-tourism authorisation, because we found no public lookup for it. We cannot tell a reader how often complications follow implant treatment carried out in any one country, because the reviews we quote do not record the country. And we cannot tell a reader what proportion of patients who travelled had a problem, because the professional survey on this page counted dentists rather than patients. Each of those is a gap in the published record, and the honest response to a gap is to name it rather than to fill it with a confident sentence.

What we are is as relevant as what we publish. We are not a clinic, an agency or a booking service; we do not rank dental practices, recommend a dentist, or provide a route to arrange treatment in Turkey or anywhere else. No clinic can pay to appear here. One limit belongs in the open alongside the others, and it is measured. A named medical editor has been appointed, and the written, dated sign-off we hold covers this page along with the rest of the site. The condition this page did not meet has since been met: its blocks are classified in our passage table — the table that carries the evidence class of each passage, and from which a page's own class is derived — and five of them are readings of ours rather than quotations, which our build will not publish without a page-by-page clinician review line recorded against them. That line is recorded against this page: the medical editor read it; a dated signature record was written and bound by a hash to those five passages. What the record does not do is print its date on the page.
