This was the first anatomy book I bought. It's at a reasonable price (unlike anatomical basis of dentistry at £60!!!) and has great illustrations. However, some of the data is misleading.
The insertion and origin points of some muscles isn't exactly right. You'll find that the authors go into great detail telling you where abouts the muscle is, but don't actually tell you the exact point which is hard because it confuses you. In Manchester Uni, our anatomy spotter is 1 minute per station, and 3 questions per station and you simply don't have the time to write a description of the point where a muscle inserts, you just want to write it and be done.
However, it is the only anatomy textbook I have found to have a good section on Lymphatics of the head and neck - with pictures! It also has a chapter on the TMJ which is useful and Local Anaesthesia. The book is split into systems (i.e. Muscular system, Vascular system, etc.) which is good because it makes things easier to locate.
My advice is to you is to buy this book - BUT make sure you have another anatomy book (Anatomical Basis of Dentistry is good - but pricey, Grays Anatomy for Students is good too) to refer to, because occasionally the data in this book is misleading.
