RESUMO
PURPOSE: The widths of anterior teeth are measured and compared to see if there was any specific ratio between the anterior teeth, and to provide some referential data for clinical application in esthetic dentistry. METHODS: Gypsum casts of the maxillary and mandibular arches were made by traditional ways. With the help of dividers and vernier calipers, the widths of anterior teeth were measured. The mean values were gained by doing the measurement several times. SAS6.12 software package was used for grouped t test, paired t test and REG regression. RESULTS: Statistically significant difference(P<0.01) was observed, when comparing the widths of anterior teeth with their ideal golden section(0.618 or 1.618). There were statistically significant differences in the correlation coefficient of anterior teeth(P=0.0001). CONCLUSIONS: The golden section is not found in the anterior teeth. There is some proportional relationships between the upper and lower anterior teeth.
