Certificate in Minor Oral Surgery (CMOS)

Exam overview

The Certificate in Minor Oral Surgery awarded by the Faculty of General Dental Practice (UK), provides dental practitioners with invaluable hands-on oral surgery experience.

Participants must undergo a summative assessment at the end of the oral surgery course to be awarded the DPCOS qualification. 

The Diploma in Primary Care Oral Surgery (DPCOS) will replace the CMOS. Find out more and apply for the Diploma in Primary Care Oral Surgery course on the FGDP website.


  • In order to be eligible for admission to the final assessment, participants must complete to the satisfaction of relevant teaching staff the prescribed period of study and satisfy any other conditions as which may be prescribed within the programme (including attendance at all course unit days and successful completion of all course assessments).
  • 25 completed cases should have been approved, from which the participant will be required to submit and will be assessed on two. 

Exam format

  • The final assessment will be in the form of a 40-minute viva examination. Each candidate will be assessed by two examiners on two submitted cases.
  • One or more cases may be selected in order to demonstrate that the participant has had a thorough understanding of the scientific and clinical principles underlying the treatment that has been undertaken.
  • The participant should demonstrate the ability to recognise any shortfall within the material that has been presented, identify the improvements that could be made and demonstrate what he or she has learnt from it.
  • The participant should have demonstrated creative thought processes in the management of the problems that were faced and demonstrated the ability to search for a satisfactory solution.
