[Relationship between the width of maxillary central incisors and philtrum].

Abstract

Size of central incisors is a significant factor in selection of anterior teeth for all types of dentures. The purpose of this study was to evaluate the relationship between the width of maxillary central incisors and philtrum. The average width of the central incisors and philtrum observed in male subjects were 8.510 mm. (right), 8.516 mm. (left) and 14.105 mm. Those in female subjects were 8.280 mm. (right), 8.293 mm. (left) and 12.271 mm. There was a significant difference (p less than 0.05) in size between the width of each central incisor and philtrum for either male or female subjects. However, there was a direct correlation between the width of the central incisors and philtrum in these 200 subjects (p less than 0.05).
