Test of a method to determine socially acceptable occlusal conditions

A method for determining the social acceptability for dental appearance across the full range of occlusal conditions found in a natural population was developed and tested. The strategy used in developing the Social Acceptability Scale of Occlusal Conditions (SASOC) was to present photographs of 100 dental study models to a large sample of high school students (n = 880) and their parents (n = 403) whose responses were measured by a semantic differential instrument. After refinement of the semantic differential instrument scale scores were derived for each study model by computing the mean individual scores. Ranks were assigned to the mean scores. The Pearsonian correlation obtained between parent and student subsamples was 0.95. The reliability and validity of SASOC were assessed. COCSTOC measures of specific occlusal traits for these 100 study models are available. The future task involves the development of a highly reliable regression equation for predicting social acceptability scores from a small number of objective physical measurements.
