Objectives: The objective of the current study was to analyze the proportions of maxillary anterior teeth with respect to golden proportion, recurring esthetic dental proportion, width/height and golden percentage ratio in adult Saudi population.

Material and methods: Maxillary gypsum casts were obtained from 200 adults. Standardized digital photographs were recorded from frontal view. The apparent and actual anterior tooth dimensions were determined using software and digital calipers, for the calculation of the esthetic parameters. Data were statistically analyzed using descriptive analysis and the One-sample t test (a=.05).

Results: The anterior teeth exhibited significantly greater width and length in males than in females. The proportions of the maxillary incisors deviated significantly from the golden proportion, except for the left lateral incisor/left central incisor ratio in males. Additionally, these proportions differed significantly from the recurring esthetic dental proportions and golden percentage. Moreover, the width-to-height ratio of the maxillary central incisor exceeded the established optimal value of 80%.

Conclusions: The golden proportion was only observed in maxillary anterior teeth only in the left lateral incisor/left central incisor, in males. other proportions diverged from golden proportion and recurring esthetic dental proportion. The width/height ratio for maxillary central incisor was also significantly different from 80% ideal, in both genders.
