Abstract

Introduction: To achieve an optimal aesthetic in the maxillary anterior teeth, the ratio of width to length of these teeth is very important. One of the practical proportions for measuring the dimensions of these teeth is the Golden Standard. This study aims to evaluate the prevalence of Golden Standard in the maxillary anterior teeth and examine symmetry on both sides and its relationship with gender.
Materials and Methods: This cross-sectional (descriptive and analytical) study was done on Kurdistan medical students in 2019-2020, 100 gypsum casts were prepared from the maxilla of students. Each cast’s photograph was taken under standard conditions. The width and length of each tooth were measured with Adobe Photoshop CS6 software and compared with the range %75-%85. The data was analyzed by t-test according to the side and gender. In this study, p value = 0.05 was considered significant.
Results: The width-to-length ratio of maxillary anterior teeth was in the range of 0.82 to 0.91 in men and 0.84 to 0.9 in women. In the comparison of the right and left sides, the most asymmetry was related to the canines of men, and the lowest asymmetry was related to the central incisor and canine of women. No significant difference due to sex was detected, except the left canine (p=0.01), which was significantly higher in women than men.
Conclusion: Due to the low prevalence of Golden Standard, instead of focusing on a fixed numerical ratio, the harmony of anterior teeth dimensions with other facial and jaw ratios should be a criterion for determining dimensions of these teeth.
