MICROANATOMY

Detailed explanation-1: -The permanent maxillary right central incisor in the Universal system is tooth number 8 while the permanent maxillary left central incisor is tooth number 9. The permanent maxillary right lateral incisor in the Universal system is tooth number 7 while the permanent maxillary left central incisor is tooth number 10.

Detailed explanation-2: -8=Third molar or wisdom tooth. Your dentist may call out these numbers at the start of your visit as he or she inspects your teeth and enlists the dental assistant’s help in charting your results. The second reason your dentist calls out numbers is to rank your teeth on the periodontal chart. What does that mean?
