Wheeler should have his dental license revoked, even if he knows his dental anatomy. I say this because he has no capacity to organize, no sense of what makes things understandable, and absolutely no clue whatsoever what a diagram or illustration is used for. This text is a disgrace to the dental field, because it makes all dental professionals look incompetent, and unable to convey information effectively.
Dental anatomy is a collection of facts that should be presented either in list form, or as text attached to a WELL-LABELED diagram, with SOME description of what's going on. Instead, wheeler presents the data in lengthy prose (which, despite its boring length, is frequently unthorough). The text is loaded with blank diagrams, some shaded/contoured, some simply line drawings, and some drawn on a graph background, almost none of which have any kind of in-graphic labeling. The only description of the illustration comes at the bottom of it, and is nothing more than an identification of tooth and aspect of the picture. In addition, he fills up the book with idiotic pictures of real teeth side-by-side which vary greatly and essentially confuse matters. Needless to say, he never bothers to label anything within these pictures.
It's extremely difficult to use this book to learn from. It's excessively tedious to get the information from the text, and almost impossible to make use of the illustrations. It's as if he initially wrote the text with no intent of including illustrations, then, at the request of others, threw in the illustrations at the very end. Apparently, Wheeler was too lazy to actually WRITE SOMETHING ON THE ILLUSTRATIONS!
If you are a dental student, and your professor recommends this book, save your money. This book is high-school. I'd give it zero stars if I could.
