RESUMEN
Objectives: The purpose of the study was to measure and compare mean enamel loss caused by microabrasion treatment of different abrasive materials under a fixed variable
Materials and Methods: In this laboratory study, three commonly used abrasive materials were compared: Dental Pumice, Zircate® Prophy Paste, Opalustre® and a controlled group [distilled water]. Hundred extracted human premolars were randomly allocated into four groups; each group was subjected to fixed pressure, time and rotational speed mimicking dental office setting
Results: Data was collected and statistically analyzed. The results of the study [p < 0.01] was statistically significant and showed that Opalustre® caused the highest mean difference in enamel loss. Followed by dental Pumice and Prophy paste in order with minimal difference between them. And the controlled group [distilled water] had the least mean enamel loss
Conclusion: microabrasion offers a great approach in treating enamel defect/staining in a minimally invasive procedure in order to achieve acceptable aesthetic results while preserving the tooth's microstructure as much as possible. As shown in the result; Combined chemical acid with mechanical abrasive particles produce most effective results
