Abstract

There are few guides to estimate the size of denture teeth. The purpose of this observational cross sectional study of Iranian adults was to evaluate the relationship between interalar width compared to intercanine tip distance and to the summed width of the maxillary anterior teeth in adults. The samples were selected from dental students in Isfahan University. Interalar width was measured with calipers. Maxillary inter-canine distance was measured between cusp tips on dental casts. Mesiodistal widths of the six anterior teeth also were measured. Independent t-tests, Pearson’s correlation coefficients, and linear regression were used for statistical analysis. Mean interalar width was 36.38 mm (sd = 3.81), intercanine tip distance was 34.15 mm (sd = 2.05), and mean width of maxillary anterior teeth was 48.23 mm (sd = 2.07). There were significant associations between interalar width and summed widths of the maxillary anterior teeth and with intercanine distance. In addition, predictive equations for estimation of tooth sizes using interalar width were calculated by regression. These statistical relationships may also be useful forensically.

Highlights

There are few guides to estimate the size correlation coefficients, and linear regression were used of denture teeth
Various guidelines have been suggested The aims of the present study were to compare IAW, for determining the maxillary anterior teeth when pre- intercanine tip distance (ICTD), and WMAT between males and females and to extraction records are not available, but different opinions derive predictive equations from a group of Iranian adults
Results of independent t-tests show that the values of IAW, ICTD and WMAT were significantly greater in males than females

Summary

Introduction

There are few guides to estimate the size correlation coefficients, and linear regression were used of denture teeth. One of the confusing and difficult aspects of complete between IAW and width of maxillary anterior teeth denture prosthodontics is the selection of appropriately (WMAT).
