As the title implies, this book is a dictionary, nothing more. I was sorely disappointed to find out that there were no pictures, diagrams, or illustrations in this book whatsoever. It does include almost every word you could think of for a dental reference, but I hoped it would have more on the morphology and anatomy of teeth. For instance, if someone wondered what a marginal ridge was, it would tell them, but without a picture to show where they are, it is very hard to grasp the concept. I would not reccommend this book for someone looking for clarification of oral structures, only for people who only want to know what something is, not where.
