Document Summary
Lingual = the side of the tooth towards the tongue. Buccal = the side of the tooth towards cheek. Labial = the front of the tooth that is facing the lips. Occlusal =across the biting surface of the teeth. Apical = down towards the root tip. Neck/cervix = towards the cervical/neck where the crown and root meet up. Mesial = going towards the midline of the dental arcade. Distal = away from the midline of the dental arcade. There are four main categories: deciduous/ adult, type (incisors, canine, premolar, molar?, position (maxillar or mandibular) and number (1st molar, 2nd molar, left or right. Universal method: it assigns discrete number to each tooth (in order, we start at the maxilla third molar on the right = tooth #1. Looking at the crown, deciduous teeth are more rounder. Enamel is thinner tooth looks more yellow since we see more of dentin, whereas permanent teeth are more white.
