Objective comparison of three different treatment modalities in the esthetic improvement of mild-to-moderate dental fluorosis: A randomized clinical trial

Objective: To compare and evaluate esthetic improvement following resin infiltration, vital bleaching, and diode laser bleaching in mild-to-moderate fluorosis conditions immediately after treatment, 1 month, and 6 months postoperatively. Study Design: Sixteen patients with Central and lateral incisors showing mild-to-moderate fluorosis according to modified Dean's fluorosis index were selected and simple randomization was done to allocate the teeth to resin infiltration group, vital bleaching group, diode laser bleaching group, and control group. Esthetic improvement posttreatment was assessed using digital image analysis using Adobe Photoshop software and color change (ΔE) was calculated. Results: The inferential statistics included Kruskal–Wallis test and Friedman's ANOVA test. Vital bleaching showed the highest esthetic improvement followed by diode laser bleaching, vital bleaching, and control group at all the different time intervals. The results, however, were not statistically significant. Conclusion: All the three treatment measures brought about esthetic enhancement with the vital bleaching group showing slightly better results when compared with other study groups.
