Mohsen Mobasseri

Introduction

Mohsen Mobasseri is a dentist who qualified in Germany in 2001, gaining the Zahnarzt qualification at RWTH Aachen, and began UK practice the following year, registered with the General Dental Council under number 81444. In 2006 he purchased a dental surgery in Camden, London, becoming practice principal under an NHS contract, and from 2015 also practised in London’s Wimpole Street area, with Invisalign orthodontics among his main practice areas.

In December 2024, after a public hearing before the GDC’s Professional Conduct Committee, Mobasseri was found to have failed to maintain an adequate standard of care and record keeping, to have retrospectively and dishonestly amended patient records, and to have dishonestly submitted inappropriate claims to the NHS. The committee directed that his name be erased from the register and suspended his registration immediately. His appeal to the High Court was dismissed in November 2025 and the sanction of erasure upheld.

Background Information

By 2019 the NHS contract at his Camden practice was worth approximately £650,000 per annum, equating to around 18,111 Units of Dental Activity, supported by three associates, hygienists, dental nurses and a reception team. The practice used Kodak R4 record keeping software until early 2019, when it was replaced by EXACT from Software of Excellence (SoE).

From some stage prior to 2018, Mobasseri made most of his clinical notes in Microsoft Word rather than in the practice software. From the end of March 2020, during the first COVID-19 lockdown, he began transferring the Word records directly into SoE, heading each entry “Transferred from [date of the appointment]” — while making significant unmarked alterations that added, altered or deleted clinical detail from appointments of weeks, months or years earlier. He said he had done this to “enhance” records whose poor standard left him shocked and embarrassed, and admitted the retrospectively entered BPE scores had been “made up” and his conduct misleading and dishonest.

In 2020 an anonymous informant raised concerns with the NHS, which investigated his claims for Units of Dental Activity. In response to an NHS letter of 21 September 2020 requesting patient records, he altered the records of fourteen patients and saved them in SoE on the morning of 19 October 2020 before submitting them, adding detail to support the corresponding claims for payment. He admitted this too was misleading and dishonest, saying he had panicked on seeing their poor quality.

The Controversy or Incident That Led to Their Cancellation

Adjudicated vs. alleged. The findings below were made on the balance of probabilities by the GDC’s Professional Conduct Committee — a regulatory panel, not a criminal court — and are not criminal convictions; most heads were admitted by Mobasseri, and the committee did not find dishonesty proved in respect of one claim, that for Patient E.

At the initial hearing, held from 25 November to 13 December 2024, the amended charge — covering some thirty patients anonymised as Patients 1–15 and A–O — alleged failure to maintain an adequate standard of care between 14 May 2019 and 9 March 2020; inadequate radiographic record keeping; failure to maintain contemporaneous records; retrospective amendment of clinical records; inappropriate NHS claims between 26 March 2018 and 29 March 2019; the amendment of records before submission to the NHS Business Services Authority on 19 October 2020; and that this conduct was misleading and dishonest.

On the clinical allegations, the committee found proved that he had failed to adequately carry out Basic Periodontal Examinations across fourteen appointments — admitted only as a failure to record — rejecting his account that they had been done but not charted. It further found he had failed to carry out sufficient treatment planning before commencing elective Invisalign treatment for patients with untreated caries (Patients 6 and 12) and periodontal disease (Patients 9 and 10); that radiographs of one patient had been stored in another patient’s records; and that he had failed to maintain contemporaneous SoE records.

On the probity allegations, it found proved the retrospective amendment of records (98 amendments for Patients 1–15); the seven inappropriate NHS claims in Schedule 8, proved in their entirety including the denied Patient I claim, which he had falsely recast as an emergency appointment; and the falsification of 27 records for 14 patients before submission to the NHS. The conduct was found misleading in its entirety, and dishonest except for the Patient E claim, where dishonesty was not found proved. For Patients B, F and K it found treatment dates had been deliberately changed to bring claims into a previous contract year; for Patients C and D, that dates had been manipulated to claim twice for the same treatment.

The committee found the facts amounted to misconduct and that Mobasseri’s fitness to practise was currently impaired on 13 December 2024, all four limbs of the applicable test being engaged: risk of harm to patients, disrepute, breach of fundamental tenets, and past and future dishonesty.

Public Reaction and Consequences

The committee considered his clinical failings remediable but not fully remedied, finding them attitudinal rather than a lack of skill, with limited insight and dismissive evidence about the importance of BPEs. His dishonesty in falsifying the records of 29 patients, including to mislead the NHS, and in submitting six inappropriate claims, went to his character and left him liable to act dishonestly again.

Aggravating factors included risk of patient harm, premeditated dishonesty for financial gain, misconduct sustained over an extended period, disregard of the profession’s regulatory systems, and a cover-up through record alteration. In mitigation it weighed his otherwise good character, absence of previous adverse findings, substantial remediation, compliance with interim conditions, remorse, testimonials, and the passage of time since the last incident in 2021.

Current Status

On 13 December 2024 the committee directed that the name of Mohsen Mobasseri (81444) be erased from the register, finding his conduct fundamentally incompatible with continued registration, and ordered immediate suspension rather than leaving interim conditions in place during the 28-day appeal period.

Mobasseri appealed on 10 January 2025. On 14 November 2025 the High Court dismissed his appeal and upheld the sanction of erasure, which then took effect.

Impact on Their Career/Life

Erasure removes Mobasseri’s name from the GDC register, ending his entitlement to practise dentistry in the United Kingdom. The immediate suspension order had already stopped him practising from December 2024, and the High Court’s dismissal of the appeal — a court ruling upholding the committee’s sanction — leaves the erasure in place.
