MDCN Dental Assessment case studies
MDCN Dental Assessment · Put your knowledge to work in context.
The MDCN Dental Assessment Examination is run by the Medical and Dental Council of Nigeria, the body whose stated mission is "To regulate the practice of Medicine, Dentistry and Alternative Medicine in the most efficient manner that safeguards best healthcare delivery for Nigerians." The Council publishes an assessment examination application route through its candidate portal, and separately publishes assessment examination pass lists, confirming that the examination is a live, results-bearing step in the Council's registration pathway rather than a routine university test. Candidates are typically dental graduates whose qualification or registration route requires the Council's assessment before dental registration proceeds; the Council lists provisional, full and temporary/limited dental registration categories, and the assessment sits alongside those routes. The MDCN Dental Assessment case studies are 5 cases and about 3,739 words.
