ABSTRACT

Pont’s index was established by himself in 1909 to anglo-saxon ethic group to predict maxillary dental arch width from the sum of the mesiodistal diameters of the four maxillary incisors. The use of Pont’s index is controversial and, there has been a recent interest in its clinical use at UNAM. The purpose of this study was to find the accuracy of the Pont’s index to half-caste race. This study aimed to evaluate Pont’s index in samples of Mexican people (n = 60) with apparently good occlusion and no orthodontic treatment. Measurements were obtained directly form plaster casts, they included mesiodistal crown diameters of the four maxillary incisors, premolar and molar widths as specified by Pont. The significant statistics difference was noted between the measured values and Pont’s estimates, on inferior arch to inferior premolar zone the index underestimated the values with 0.7 mm (p = 0.017), on inferior molar zone over estimated the values with 2.4 mm (p ‹ 0.0001), however the upper arch didn’t have statistical difference. So the Pont’s index is of little accuracy for subjects like the ones in this study.
