A test of the clinical skills and knowledge of overseas dentists (from outside the European Economic Area) who wish to apply for full registration with the General Dental Council (GDC) of the UK. It is divided into three parts. Part A consists of a written paper and two oral examinations; part B is a series of practical exercises forming a simulated clinical assessment; and part C consists of two written papers and a clinical patient examination followed by an oral examination. This examination was replaced in 2007 by a new statutory examination, the Overseas Registration Examination (ORE), which is in two parts; part one is a knowledge test consisting of two, three-hour written papers undertaken on a computer, and part two is made up of four elements: an objective structured clinical examination (OSCE), practical exercises undertaken on dental manikins, a diagnosis and treatment planning exercise, and an examination in medical emergencies. The GDC expects candidates to have spent an appropriate number of hours treating patients in the dental chair before applying to sit the examination.
