MOH Oman (OMSB) Endodontics Exam Quick Summary

The OMSB Endodontics specialist exam is a two-stage process: a Pearson VUE-delivered written exam (150 MCQs, roughly 3 hours, 60% passing score), followed by a mandatory interview/viva for candidates who pass the written stage.

MOH Oman (OMSB) Endodontics Specialty Exam

The Oman Medical Specialty Board (OMSB) conducts this specialty exam to assess a dentist's knowledge and clinical judgment in the diagnosis and management of dental pulp and periapical conditions, including root canal therapy, endodontic emergencies, and pain management. It is one of several OMSB dental specialty tracks alongside General Dentist and Prosthodontics, each with its own exam pattern and eligibility requirements.

Unlike the OMSB General Dentist exam, the Endodontics specialist pathway has two stages: the written multiple-choice exam, followed by a mandatory interview (viva) as part of the application process.

Eligibility criteria for the OMSB Endodontics exam

To apply for the OMSB Endodontics specialist exam, candidates are generally expected to meet the following:

Primary dental degree: A recognized Bachelor of Dental Surgery (BDS), Doctor of Dental Medicine (DMD), or equivalent qualification from an accredited institution.
Specialization in Endodontics: Completion of a Master's, Diploma, or equivalent postgraduate qualification specifically in Endodontics from a recognized institution.
Post-specialization clinical experience: Generally 2-3 years of specialized clinical training/experience in Endodontics after your postgraduate qualification.
Valid license & Good Standing Certificate: An active license to practice in your home country (or country of last employment), plus a Certificate of Good Standing typically valid within the last 6 months.
DataFlow Primary Source Verification: All educational, professional, and licensing documents verified through DataFlow. See the full OMSB general eligibility requirements for the complete document checklist.

Confirm your own eligibility status directly with OMSB rather than assuming a general figure applies to you, since specific requirements can vary by application track.

OMSB Endodontics exam syllabus

The exam draws from the following subject areas, reflecting the discipline of endodontics itself:

  • Dental pulp and periapical tissues
  • Diagnosis and treatment planning
  • Endodontic pain and emergencies
  • Primary endodontic treatment procedures (root canal therapy)
  • Endodontic failures and retreatment
  • Endodontic surgeries
  • Dental trauma
  • Regenerative endodontic procedures
  • Endo-perio lesions
  • Management of medically compromised patients

Most questions are clinical scenario-based MCQs with a single correct answer, delivered as a computer-based test.

Passing score (written)

Passing the written exam is not the final step: candidates must then pass an interview (viva) held in Muscat before a multi-member panel, using case scenarios relevant to endodontics. A written score above roughly 65% generally allows more viva attempts if needed. The exact question count, duration, and passing score can differ from DHA, DOH, and other Gulf authorities' versions of this specialty exam -- always confirm the OMSB-specific figures directly with OMSB.

Preparation tips for the OMSB Endodontics exam

Master pulp diagnosis
Be precise on reversible vs. irreversible pulpitis, and pulpal vs. periapical diagnoses -- a heavily tested area.
Prepare for the interview separately
The viva tests case-based clinical reasoning verbally in front of a panel -- practice explaining your diagnosis and treatment plan out loud, not just recognizing the right MCQ answer.
Know trauma protocols
Review avulsion, luxation, and root fracture management timelines -- a recurring high-yield topic.
Practice under timed conditions
Simulate the roughly 3-hour, 150-question format so pacing isn't a surprise on exam day.

Sample Practice MCQs

Test your knowledge with these original clinical scenario-style questions. Tap a question to reveal the answer.

> Question 1: Pulp Diagnosis
A patient reports sharp pain to cold that lingers for over a minute after the stimulus is removed, with no spontaneous pain. What is the most likely diagnosis?

Answer: Symptomatic irreversible pulpitis.

Explanation: Lingering pain to cold beyond a few seconds is the classic feature distinguishing irreversible from reversible pulpitis, which typically resolves within seconds of stimulus removal.
> Question 2: Endodontic Retreatment
A previously root-canal-treated tooth presents with a persistent periapical radiolucency and the canals show evidence of underfilled obturation with no post or crown present. What is the most appropriate management?

Answer: Nonsurgical endodontic retreatment.

Explanation: When the coronal restoration and canal access allow it, nonsurgical retreatment to correct the inadequate obturation is preferred over surgical intervention as the first-line approach, since it directly addresses the likely cause -- persistent intracanal infection from incomplete filling.
> Question 3: Dental Trauma
A permanent tooth is avulsed and reimplanted within 30 minutes with the periodontal ligament kept viable. What is the recommended splinting duration?

Answer: A flexible splint for 2 weeks.

Explanation: Current trauma guidelines recommend a short-duration flexible splint (about 2 weeks) after reimplantation with a viable periodontal ligament, to allow physiological healing rather than ankylosis.

Frequently Asked Questions

> What does the OMSB Endodontics exam cover?

It covers dental pulp and periapical tissues, diagnosis and treatment planning, endodontic pain and emergencies, root canal therapy, retreatment, endodontic surgery, dental trauma, regenerative procedures, endo-perio lesions, and management of medically compromised patients.

> Is there a viva or interview component?

Yes. After passing the written exam, candidates must pass an interview (viva) held in Muscat before a multi-member panel, using case scenarios relevant to endodontics. A stronger written score generally allows more viva attempts if the first one doesn't succeed.

> How much experience do I need to sit the OMSB Endodontics exam?

Candidates generally need a recognized postgraduate qualification in Endodontics plus around 2-3 years of specialized clinical training or experience, though the exact requirement should be confirmed directly with OMSB.

> Is there an exemption from the OMSB Endodontics exam?

No confirmed, published OMSB exemption pathway specific to Endodontics exists at this time. If you hold a specialist board certification and want to check your own eligibility for an exemption, contact OMSB directly.
