It has always been argued as to what constitutes good dental esthetics, as it can vary from person to person depending on personal experiences and social ambiance. Recurring esthetic dental proportion has been stated to be an essential tool for achieving esthetics and harmony in smile. The objective of this study was to determine the prevalence of recurring esthetic dental proportion in maxillary anterior teeth widths in a selected sample of Pakistani population. Two hundred dental students were included in the study, included 84 male subjects and 116 female subjects with the age range of 18 to 30 years. Photographs of the subjects were taken using a digital camera (Casio Exilim; EX-S5.Casio computer Corp, China. 10.1 megapixels with 100- mm macro lens and a point flash) and analyzed using Adobe Photoshop 7 software. The width of maxillary central incisors, lateral incisors and canines were found out using the measuring tool provided in the software. The Data were subjected to statistical analysis, (descriptive statistics and t-test, level of significance was set at P<0.05). The values of the recurring esthetic dental proportion (RED) were not constant in this study, and the farther the one moves distally from the midline the higher the values. The RED proportion theory can be applied to relate the successive widths of the maxillary anterior teeth if percentages are adjusted taking into consideration the ethnicity of the population, within the confines of this study Recurring esthetic dental proportion was not seen in the widths of natural maxillary anterior teeth.
