Effect of Combining Minimal Invasive Modalities on Treating Mild Dental Fluorosis: An In vivo Study

BACKGROUND: Fluorosis is intrinsic tooth discoloration which compromises esthetics depending on its severity. AIM: The aim of the study was to assess efficiency various treatment modalities in esthetic improvement mild fluorosed teeth. MATERIALS AND METHODS: Four patients with 48 teeth were randomly assigned four (n = 12). included M1: power bleaching, M2: microabrasion and M3: bleaching resin infiltration M4: microabrasion, infiltration. Color parameters (L, a, b) visible color change (ΔE) measured by spectrophotometer (VITA Easyshade®) at baseline, immediately after treatment, 3, 6, 9 months. STATISTICAL ANALYSIS: Two-way ANOVA applied test interaction between different variables. repeated measures followed Duncan multiple range tests (DMRTs) compare groups. RESULTS: All showed significant all-time points compared baseline. highest recorded other modalities. Bleaching alone had lowest change. CONCLUSION: Resin more effective dental fluorosis either or combination bleaching.
