Range and mean discordance of individual tooth width of the mandibular anterior dentition.

Proper diagnosis of tooth size for each patient is critical in treatment planning for restorative dentistry. The purpose of this study was to find a clinically relevant and applicable range and mean discordance of individual tooth width of the mandibular anterior dentition. The central incisor (CI), lateral incisor (LI), and canine (CA) teeth varied in range from 4.5 mm to 6 mm, 4.5 mm to 7 mm, and 5.5 mm to 8 mm, respectively (N = 417). Nearly 90% of the patients fell within +/- 0.5 mm of the combined gender normative values. The results suggest that there exists on average discordance between normative values and actual tooth width of the mandibular anterior dentition in a population of male and female patients.
