Dental Terminology And Their Uses

DENTAL VOCABULARY

One of the learning parts of dentist/dental team is to understand the basic part of dental/medical terminology. It may seems difficult at first, long, but later look impressive-looking words and understandable. By learning what the word parts mean, it is much easier to understand what a brand new word is, even if you have never seen or heard it before. Most medical terms originated in either Greek or Latin.
