Abstract

An investigation was conducted to determine if statistically significant differences in enamel abrasion occurred when molar specimens were air polished (AP) and rubber cup polished (RCP). Thirty human molars were randomly divided into two groups. Molar buccal surfaces were masked longitudinally to provide control surfaces. Each polishing technique was applied for two minutes and thirty seconds on fifteen exposed enamel surfaces. Buccal enamel surfaces were divided into coronal and cervical sections for microscopic review. Six enamel thickness measurements were determined for each coronal and cervical enamel section using the scanning electron microscope. Measurements of AP and RCP coronal and cervical enamel sections were compared within and between groups to determine differences between polishing methods on enamel abrasion. Data were analyzed at the 0.05 level of significance using analysis of variance. Results revealed no differences in the amount of enamel abrasion for either polishing technique.
