Abstract

Objective To evaluate the average value and to study the influence of gender and age on the clinical size of six upper natural anterior teeth. Materials and methods Eighty Thais with age range 25-80 years were randomly selected and divided into male and female equally. The width and the length of upper anterior teeth were measured in two dimensions from casts. The relationship between the obtained data and other factors such as intercanine width or the adjacent tooth width, were analyzed with T-test at 95% confidential level. Results When compared between genders, it was found that the average width of upper anterior teeth in the same position had no significant difference except in the left canine. When considered right and left sides, there was no significant difference. The average width of central and lateral incisors in both genders were 8.7 ± 0.6 and 7.3 ± 0.6 mm, respectively. For canine in male and female are 8.2 ± 0.6 and 8.0 ± 0.4 mm., respectively. The average length found significant difference between genders only in lateral incisor of both sides. When considered right and left side, there was no significant difference. The average length of central incisor and canine in both genders are 9.8 ± 0.9 and 9.4 ± 0.9 mm., respectively and the values of lateral incisors in male and female are 9.2 ± 0.9 and 8.5 ± 0.9 mm., respectively. Anyway, the relation between age and width or length of every upper anterior tooth has no significant difference. Conclusion The width of upper central incisors is 24 percent of the intercanine distance in both genders. Gender influences on the clinical size of upper lateral incisor while age does not.
