Despite the various updates and revisions, the aims and objectives of this book remain the same, namely to provide a basic, but comprehensive, practical account of what we consider to be the essential subject matter of both dental radiography and radiology as required by undergraduate and postgraduate dental students. As in previous editions, some things have had to be omitted, or sometimes, over-simplified. However, the book remains first and foremost a teaching manual (albeit more colourful) rather than a comprehensive reference. We believe that the content remains sufficiently broad, detailed and up-to-date to satisfy the requirements of most undergraduate and postgraduate examinations and the needs of most general dental practitioners. Students are encouraged to build on the information included here by using the excellent and more comprehensive textbooks available.
We hope that once again the result is a clear, logical and easily understandable textbook that continues to make a positive contribution to the challenging tasks of teaching and learning dental radiology.
