ORE Part 1 study guide
ORE Part 1 · Work through your exam, one topic at a time.
The Overseas Registration Examination (ORE) is the General Dental Council's route by which dentists who qualified outside the relevant UK/EEA frameworks can demonstrate the knowledge, skills and professional attributes expected of a dentist practising in the United Kingdom. It is set and administered by the GDC and is normally taken in two parts, Part 1 and Part 2; candidates progress through a sequence of stages, from application and booking through to sitting each part and receiving results. The ORE Part 1 study guide has 5 sections and about 1,654 words.
01Applied biomedical and dental sciences
ORE Part 1 rewards candidates who can travel from a basic-science fact to a clinical decision. In anatomy, know the trigeminal branches and the practical consequences of nerve injury: the lingual nerve lies lingual and inferior to the third molar socket and carries taste from the anterior two-thirds of the tongue via chorda tympani.

Restorative questions test adhesion and stress. Understand acid-etch bonding to enamel (micromechanical, resin tags) versus dentine bonding (hybrid layer, smear-layer modification, wet dentine), and the difference between etch-and-rinse and self-etch systems.

Periodontology now follows the 2017 World Workshop framework: a patient is diagnosed with gingivitis or periodontitis, and periodontitis is described by stage (I–IV, reflecting severity and complexity) and grade (A–C, reflecting rate of progression using bone loss/age, smoking and diabetes). You must interpret the Basic Periodontal Examination: each sextant is screened with a WHO-12 probe and one code recorded - 0 (no pocket over 3.5 mm, no bleeding), 1 (bleeding), 2 (calculus or plaque retentive factors), 3 (pocket 4–5 mm), 4 (pocket 6 mm or more) - with an asterisk added where there is furcation involvement, mobility of 2 or more, or recession of 3.5 mm or more.
320 words, about 2 min04Oral medicine, oral pathology and radiology
Oral medicine questions are built around history and red flags. Any ulcer persisting beyond three weeks, a single ulcer that is indurated, fixed to deep tissues, or associated with lymphadenopathy or unexplained bleeding must be treated as suspected malignancy and referred urgently for biopsy.
318 words, about 2 min05Paediatric dentistry, orthodontics and dental public health
Paediatric questions test chronology and prevention. Know eruption timing (primary incisors around 6–10 months, primary dentition complete by about 2.5–3 years; first permanent molars and lower incisors around 6 years) and the difference between exfoliation dates and eruption dates.
