Abstract: Determination of width of maxillary anterior teeth in case of completely edentulous patients is one of the difficult challenges encountered by dentists during processing of complete denture in absence of pre extraction records. This article explains on reliability of Sear’s cepholometric index in determination of width of maxillary anterior teeth in South Indian population.The aim of the study is to evaluate the reliability of Sear’s cepholometric index in determination of width of maxillary anterior teeth. In our study, 20 patients of age group 45 years (11 males and 9 females) for their dental treatment were included as study samples. Informed consent was obtained from them. Circumferential diameter of forehead was measured in antero-posterior extent from the point of glabella to inion using a thread in centimeters. The obtained value was divided by 13 to obtain combined width of maxillary anterior teeth. Following which, the actual width of maxillary anterior teeth was measured from right canine eminence to left canine eminenceintraorally using a thread in centimeters. The results obtained were tabulated and statistically analysed. On statistical analysis, using independent sample test(p value<0.01) shows there is a significant correlation between Sear’s cepholometric index and actual width of maxillary anterior teeth in selection of teeth for completely edentulous patients. Hence Sear’s Cepholometric index can be used as a highly valid indicator for selecting maxillary anterior teeth in completely edentulous patients.
