Clinical effectiveness of two microabrasion materials for the removal of enamel fluorosis stains

Abstract

This study evaluated the effectiveness of two microabrasion products for the removal of enamel fluorosis stains. Using a split-mouth study design, two operators used PREMA (PM) and Opalustre (OP) to remove fluorosis-like stains from 36 subjects (10-12 years old). Both products were rubbed onto the surface of the affected teeth for 30 seconds. This procedure was repeated five times during each clinical appointment. A maximum of three clinical appointments were scheduled. The subjects and/or their parents were questioned about their satisfaction with the treatment. Two blinded evaluators appraised both sides of the mouth using a visual scale system. The data were analyzed by Friedman repeated measures ANOVA and Wilcoxon test. The majority of the subjects (approximately 97%) reported satisfaction at the end of the treatment (p=0.0001). A significant improvement in appearance was detected after the second clinical appointment when using PREMA and Opalustre (p<0.002 ). After the first clinical appointment, OP showed a statistically higher mean rating for improvement in appearance (3.4 ± 0.7) than PM (2.4 ± 0.5) (p=0.002). © Operative Dentistry.
