Abstract
Seventy subjects in both sex aged at the twenties were selected to examine the occlusal wear facets on occlusal surfaces of premolars and molars.
The results were concluded as follows ;
1. Total frequency of occlusal wear facets were prominent on the mesiolingual cusps of molars and on the buccal cusps of first premolars in both sides of upper jaw and on the distobuccal cusps of molars and buccal cusps of premolars in both sides of lower haw.
2. Vertical occlusal wear facets were same frequency as that of total occlusal wear facets in the frequency.
3. Vertical occlusal wear facets were prominent on the lingual inclines and distal incli-nes of cusps in both sides of upper jaw but statistically lingual inclines of left second molar, left first premolar, and both sides of first premolars were significant, In the lower jam*, buccal inclines and distal inclines of both sides of molars and premolars were prominent but statistically distal inclines of right first molar, left second molar and left molar were not significant.
4. It was functional cusps of both jaws that reveals the occlusal wean faces frequently,
