Dental Terminology Abbreviations

If someone wants to say a mouthful, all he need do is utter a word of dental terminology. It has some of the longest, most difficult words to pronounce for a lay person. For example, "perio" is a well known abbreviation in dentistry that means periodontal disease. Or, perhaps it means peridontitis. It actually means both of these words and more. But wait, we're not stopping with just one abbreviation.
