Notices

Knowledge and best practice in this field are constantly changing. As new research and experience broaden our understanding, changes in research methods, professional practices, or medical treatment may become necessary.

Practitioners and researchers must always rely on their own experience and knowledge in evaluating and using any information, methods, compounds, or experiments described herein. In using such information or methods they should be mindful of their own safety and the safety of others, including parties for whom they have a professional responsibility.

With respect to any drug or pharmaceutical products identified, readers are advised to check the most current information provided (i) on procedures featured or (ii) by the manufacturer of each product to be administered, to verify the recommended dose or formula, the method and duration of administration, and contraindications. It is the responsibility of practitioners, relying on their own experience and knowledge of their patients, to make diagnoses, to determine dosages and the best treatment for each individual patient, and to take all appropriate safety precautions.

It is now 20 years since the first edition of Essentials was published and I felt that the time was right for the injection of new ideas and to bring on board a co-author. I am delighted that my friend and colleague for many years, Nicholas Drage, accepted both the offer and the challenge.

Together we have gone through, revised and updated every chapter. Now that Cone Beam CT is established as the imaging modality of choice in certain clinical situations, this section has been expanded and numerous new examples of advanced imaging have been added throughout. We have also replaced some of the conventional images with new and better examples.

A major change has been the establishment of a website linked to the book. This has allowed us the opportunity to remove the detailed UK legislative details (only relevant to UK dentists) from the book. We can now update this information, as and when necessary, and readers from outside the UK are spared unnecessary and irrelevant details. More importantly the linked website has given us the opportunity to include on-line self-assessment questions based on each chapter. We hope this innovation will provide a useful additional teaching and learning resource for students and practitioners.

The aims and objectives of this book remain the same, namely to provide a basic and practical account of what we consider to be the essential subject matter of both dental radiography and radiology required by undergraduate and postgraduate dental students. As in previous editions some things have inevitably had to be omitted, or sometimes, over-simplified. It therefore remains first and foremost a teaching manual, rather than a comprehensive reference book. We hope the content remains sufficiently broad, detailed and up-to-date to satisfy the requirements of most undergraduate and postgraduate examinations. Students are encouraged to build on the information acquired here by using the excellent and more comprehensive textbooks already available.

Once again, we hope that the result is a clear, logical and easily understandable text, that continues to make a positive contribution to the challenging task of teaching and learning dental radiology.

As with previous editions, this edition has only been possible thanks to the enormous amount of help and encouragement that we have received from our families, friends and colleagues (now too numerous to mention them all by name) in both London and Cardiff.

Over the years many people have contributed their help and advice for which we are very grateful, but none more so than Professor Rod Cawson who died in the summer of 2007. Without his help and involvement the first Essentials manuscript would never have been completed. Sadly, for the first time, there is no Foreword written by him in this edition. However, his unfailing support and encouragement will never be forgotten.

For this edition we would like to thank in particular Chris Greenall and Tim Huckstep from the Dental Radiology Department in Cardiff Dental Hospital and Christie Lennox from the Dental Illustration Unit in Cardiff University for their help in producing many of the new radiographic images. We would also like to thank Wil Evans for his help with the section on radiation dose and Arnold Rust for his help with the section on dosemeters.
