A must-have resource for those preparing for the MJDF, MFDS, ORE, and other dental examinations

Single best answer (SBA) questions are widely used in dental examinations including the Membership of the Joint Dental Faculties (MJDF), Member of the Faculty of Dental Surgery (MFDS), and the Overseas Registration Exam (ORE). Single Best Answer Questions for Dentistry is a comprehensive revision tool designed to help dental students be thoroughly prepared on exam day.

Each clearly written SBA question is accompanied by an accurate answer and a full explanation, providing students with a quick and easy-to-access way to revise. The SBAs cover a broad range of specialties within dentistry such as restorative dentistry, oral surgery, oral pathology, paediatric dentistry and orthodontics, periodontology, oral medicine, and more. All terms throughout the book conform to the latest evidence and guidelines, such as the most recent classification of periodontal disease, and match the level of knowledge required for success on current dental examinations. Written by a leading dental practitioner, this valuable resource:

• Comprises 10 chapters, organised by specialty, each containing 20 to 30 SBAs with their associated answers and explanations
• Covers various dental specialties and topics including restorative dentistry, radiology, pharmacology, human disease, and dental materials
• Presents a simple and efficient question-and-answer format that is ideal for exam revision
• Helps strengthen students' skills in clinical problem solving and decision making

Containing more than 280 questions of varying difficulty levels as well as numerous high-quality images and radiographs, Single Best Answer Questions for Dentistry is essential reading for all dental students and a useful tool for practicing dentists wanting to test or refresh their knowledge.

CHAPTER 1
Restorative Dentistry

1. What is the ideal freeway space (FWS) for complete dentures?
   1. 1–3 mm
   2. 2–4 mm
   3. 3–5 mm
   4. 4–6 mm
   5. 5–7 mm
2. Which of the following describes a Kennedy Class II, in Kennedy’s classification for partially dentate patients?
   1. Patient with bilateral free‐end saddles
   2. Patient with a unilateral free‐end saddle
   3. Patient with a unilateral bounded saddle
   4. Patient with an anterior bounded saddle
   5. Patient with a bilateral free‐end saddle and a missing UR2
3. What is the primary purpose of indirect retention in partial denture design?
   1. Prevent displacement of the denture in the axial direction
   2. Aid insertion and removal of the denture
   3. Prevent lateral forces on teeth
   4. Prevent tipping/rotation of the denture about a fulcrum
   5. Allow for effective cleaning
4. A sclerosed canal can be more easily navigated using which of the following irrigants?
   1. Chlorhexidine
   2. Sodium hypochlorite
   3. Ethylenediaminetetraacetic acid (EDTA)
   4. Water
   5. Calcium hydroxide
5. Which graph best describes the changes in plaque pH in response to food?
   1. The Miller Curve
   2. The Monson Curve
   3. The Stephan Curve
   4. The David Curve
   5. The Spee Curve
   1.b
   This is the ideal FWS. However, often, if patients have had a different FWS for a long period of time, it may be necessary to adhere to their existing FWS. This is primarily to ensure good habituation.
   2.b
   Kennedy Class II is a unilateral free‐end saddle. It may also have modifications. It is only Kennedy Class IV that does not have any modifications, as the most posterior saddle dictates the class and, thus, any modifications would in fact fall in to a different class.
   3.d
   Indirect retention helps prevent tipping of the denture about a fulcrum created by the denture components. It can be provided by other denture components including clasps, rests and connectors.
   4.c
   EDTA is a chelating agent used to soften the dentine and allow easy exploration of sclerosed canals. Sodium hypochlorite is the typical irrigant for root canal treatments. Calcium hydroxide is better used in a pulpless, temporary dressing.
   5.c
   The curve demonstrating plaque pH changes associated with snacking is the Stephan Curve. This helps demonstrate how frequent snacking causes the pH to drop below the critical pH more frequently. As a result, an individual is more likely to develop caries.
6. Which of the following is the advancing edge of a carious lesion in enamel?
   1. Dark zone
   2. Body of the lesion
   3. Surface zone
   4. Translucent zone
   5. Zone of sclerosis
7. Which of the following is a crucial feature of amalgam cavity design?
   1. 110° cavo‐surface angle
   2. Presence of unsupported enamel
   3. Leaving caries at the amelo‐dentinal junction (ADJ)
   4. Placement of pins
   5. Undercuts
8. Which of the following best describes retruded contact position (RCP)?
   1. The position of the mandible, relative to the maxilla, when the teeth are maximally intercuspated
   2. The first tooth contact when the condyle lies in its most favourable position in the glenoid fossa
   3. The position of the mandible when the condyle...
