Abstract
Background and aims. Various methods are used to measure the size and form of the teeth, including the golden proportion,
and the width-to-length ratio of central teeth, referred to as the golden standard. The aim of this study was to evaluate
the occurrence of golden standard values and golden proportion in the anterior teeth.
Materials and methods. Photographs of 100 dentistry students (50 males and 50 females) were taken under standard
conditions. The visible widths and lengths of maxillary right and left incisors were calculated and the ratios were compared
with golden standard. Data was analyzed using SPSS 14 software.
Results. Review of the results of the means showed statistically significant differences between the width ratio of right
lateral teeth to the central teeth width with golden proportion (P<0.001). Likewise, the difference was significant for the left
side, too (P<0.001). Test results of mean differences showed that the mean difference between proportion of right laterals
to centrals with golden proportion was significant (P<0.001). The difference was significant for the left side, too (P<0.001).
As a result, there is no golden proportion among maxillary incisors. The review of results of mean differences for single
samples showed that the mean differences between the proportion of width-to-length of left and right central teeth was statistically
significant by golden standard (P<0.001). Therefore, considering the width-to-length proportion of maxillary central
teeth, no golden standard exists.
Conclusion. In the evaluation of the width-to-width and width-to-length proportions of maxillary incisors no golden proportions
and standards were detected, respectively
