Abstract

Although teeth wear is a physiological process, bruxism or teeth grinding is indicated as the sole etiological factor involved, without taking into consideration other wear processes, such as erosion and abrasion. Current descriptive and longitudinal analysis evaluates the surface roughness in teeth as dental wear standard in females diagnosed with acid erosion or attrition. Sample comprised 20 females, aged between 20 and 50 years old, divided into Group A (n=9) characterized by teeth grinding, and Group B (n=11) without bruxism. A subdivision was also included by dividing those with erosion factors in the diet. After a thorough exam, molds of the upper teeth with Addition Silicon Impression were undertaken to obtain the patients´ dental replicas. Mitutoyo Surface Roughness Analyzer SJ-301 was employed to investigate the samples´ surface roughness. All participants of Groups A and B with erosion factors had an increase in Ra at 25.16%, 200% and 74.9%, respectively. Erosion-less Group B was the only one with a non-significant difference. Difference in the Abbot-Firestone curve was sharp only in groups with erosion factors. Results revealed that the standard of dental wear with erosion factors was high when compared to attrition-caused wear.
