Abstract

Background & Aim: One of the most important tasks in esthetic dentistry is creating harmonious proportions between the WIDTH OF MAXILLARY ANTERIOR TEETH when restoring or replacing these teeth. The concept of GOLDEN PROPORTION is a main guideline, introduced in this field. Since smile is the best judgement for assessment of dentofacial esthetics in practice, this study aimed to investigate the existence of the GOLDEN PROPORTION in individuals having ESTHETIC SMILES.Method &Materials: This descriptive study with sequential sampling has been conducted with 157 dental students (75 women and 82 men) with ages ranging from 18 to 30. The students whose smiles in normal situation didn't develop visual tension with regard of study's criteria and their own criteria were selected as individuals having esthetic smile. An image measurements program (Dimaxis 2.3.1, Planmeca, Finland) was used to measure the apparent mesiodistal width of 6 maxillary anterior teeth on the scanned photographs of these subjects. The existence of the GOLDEN PROPORTION was investigated in the width ratios of maxillary anterior teeth. Then the existence of the GOLDEN PROPORTION was investigated within the Preston's range in the individual who had completely aligned maxillary anterior teeth. Finally, the existence of the GOLDEN PROPORTION in maxillary anterior teeth was determined according to gender statistically with X2 scores.Results: The GOLDEN PROPORTION of 0.6 within the 0.55-0.64 range, and 0.62 within the Preston's range (0.61-0.63) was not found to exist between perceived maxillary anterior teeth width of individuals having ESTHETIC SMILES. Alignment of the maxillary anterior teeth or gender did not affect the existence of the GOLDEN PROPORTION. Conclusion: GOLDEN PROPORTION doesn't exist as a common factor in esthetic smile and can not be used as a constant proportion to create harmonious proportion between the widths of maxillary anterior teeth.
