ABSTRACT
The scope of the study was to determine the ratio between maxillary anterior teeth widths to width of facial proportions in a dental college in Karachi, Pakistan. The widths of facial proportions were determined using a Vernier Caliper. The widths of maxillary anterior teeth were measured intraorally using Boley's gauge on a sample of 116 human subjects visiting the Diagnosis Department in Dr Ishrat-ul-Ebad Khan Institute of Oral Health Sciences, [DIKIOHS], Dow University of Health Sciences, Karachi, Pakistan. All readings were measured in millimeters. Pearson's correlation test was applied and it showed no significant relation between width of central incisor and bizygomatic width [0.11]. But a significant relationship was found between intercanine width and width of mouth [0.03], width of philtrum and mean width of central incisors [p=0.05], interalar width and intercanine width [p=0.00]. Facial proportions solely do not provide a secure prototype in selecting maxillary anterior teeth and could result in selecting larger teeth in size
