Preface

I conceived the Dental Dictionary to assist TLC Dental Group patients in better understanding our dental services by providing them with  short yet meaningful definitions of common dental terms.

As a Syracuse, NY dentist drawing on many years of dental practice I have compiled a list of essential dental terms. For each entry I have spared you the task of searching the Web for a dental term and being greeted by an array of sparse dental glossaries and quasi dental dictionaries. In lieu of that ordeal, you may simply click on our Contents page and then click on the first letter of your desired dental word to quickly locate it.

Should you not find a dental term in this dictionary, you might consult two standard, unabridged dictionaries to which I am beholden: Mosby’s Dental Dictionary and the Oxford Dictionary of Dentistry.

In closing this Preface, I would acknowledge my mother Helen, my father Joseph, and particularly my wife Marsha who provided extensive and invaluable editorial assistance in this work. Without them I would not have a dental practice much less a dental dictionary.
