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