RESUMO

The goal of this research was to determine the biometric dimensions of human teeth, measuring the width of the mesial-distal, bucco-lingual and ocluso/ incisors-cervical. The study was of a cast model of 57 patients, 31 females with an average age of 15 years and 5 months and 26 males with an average age of 16 years and 6 months. The sample was previously qualified adopting the criteria of the six keys to normal occlusion concept, Andrews et al had their median values compatible with those of Bolton. Two examiners used a digital sliding caliper with the original tips (short) and modified tips (long). After the results were obtained and the statistical analysis was complete, it was possible to conclude:- the dental elements were shown to be symmetrical in the dental arches in both genders. The dental dimensions were smaller on the females than those of the males, therefore when studied the results for each gender must be separated. For each gender, it was possible to create a table of median values of the three dimensions, percentage occurrence between these dimensions and their respective standard deviations. With these values it was possible to develop an expression called the C equation and a "C" percentile table. With the aid of both it is possible to just measure one of the dimensions of a tooth and to calculate the other two probable dimensions of any tooth in the dental arches.
