ABSTRACT
The study for beauty can be traced back to the earliest civilizations. Many factors influence the perception of beauty, and esthetic dentistry continues to grow as a major part of overall dentistry. One of the most important factors in beauty of the teeth is the proportion of them to one another, and golden proportion is determined to be 1.618. The purpose of this study was to determine the average dimensions of the six maxillary anterior teeth in specific population and to evaluate relationship between these dimensions. Casts and photographs were obtained from 100 students of Isfahan Dental School with normal occlusion. Measurements of length and width were made on the casts and photographs using an electronic digital caliper. Average dimensions and ratios were calculated. Dimensions in men were larger than dimensions in women but most ratios in men and women were not different. All values in left and right were approximately equal. In addition the golden proportion was not found in ratios
