Review Questions for Dentistry is accompanied by a companion website:

The website includes:

• Interactive Multiple Choice Questions (MCQs)

The primary purpose of any test question is to test your breadth and depth of knowledge about a subject. It may seem obvious, but reading the question carefully is mandatory. It takes time to understand what is being asked and then formulate the best response. While a particular answer may be factually correct, it may not be the best response to the question. I have also tested the application of knowledge whenever possible, so that it is not sufficient to only know a particular piece of information; the student has to appreciate how that information is used in clinical practice. I have divided the text into an introductory section and a later section which explores the subject in more detail.

An explanation of the correct answer is also added, using the best current research evidence. In the later sections, especially, supporting references are quoted. The introductory sections are suitable for preparation for the Bachelor of Dental Surgery degree, whereas the later sections have been prepared with higher examinations in mind, for example the Membership of the Joint Dental Faculties (MJDF) examination. The new format of Part 1 of the MJDF (from April 2016) will comprise 150 Single Best Answer Questions in a 3-hour examination. This book is intended to test a candidate's understanding of high-quality healthcare provision, which is also the main objective of the MJDF and the Overseas Registration Examination (ORE). At present, Part 1 of the ORE consists of Extended Matching Questions and Single Best Answer Questions.

I have used current curricula in various dental schools to develop as comprehensive a range as possible. Students have been involved in developing the questions, with their feedback being used to refine some questions. References are included to support the veracity of the correct answers whenever possible. I have varied the type and format of questions to avoid the reader becoming tired and bored with the same presentation of questions. Only one option is the correct answer, unless stated otherwise.

I hope to stimulate readers to read around the topics covered here. No one text can cover the huge variety of knowledge needed in the different disciplines of dentistry.

1. The ideal position for the access cavity in anterior maxillary teeth should
   1. conserve as much of the pulp chamber roof as possible
   2. be positioned close to the incisal edge
   3. be positioned over the cingulum of the tooth
   4. be positioned to allow access to the apical region of the root canal
   5. utilise any existing cervical labial restorations to avoid any further damage to the tooth
2. Choose the option which correctly completes this sentence. The working length can be defined as the distance from a reference point on the crown of the tooth
   1. to the cemento-dentinal junction of the root apex or apical constriction
