Context: Aesthetic concerns due to dental fluorosis (DF) considerably impact pyschosocial health in young children and requires aesthetic microinvasive treatment. Aims: The aim of this study was to use quantitative light-induced fluorescence to evaluate two intervention protocols: microabrasion with resin infiltration and microabrasion with remineralization and assess which brings about more fluorescence gain; better colour masking and greater patient satisfaction among subjects with dental fluorosis. Methods and Material: 120 maxillary central incisors with Grade 3 DF (Dean's Fluorosis Index) were randomly distributed into four groups: I-microabrasion + resin infiltration (fluorosis with stains); II-microabrasion + remineralization (fluorosis with stains); III-microabrasion + resin infiltration (fluorosis without stains); IV-microabrasion + remineralization (fluorosis without stains). At baseline, post-microabrasion and post-intervention Quantitative light-induced fluorescent images were captured. Fluorescence gain (ΔF) was analysed from the blue light images. The white light images were used to evaluate post intervention colour difference (ΔE = [(ΔL*) 2+(Δa*) 2+(Δb*) 2]1/2) and child satisfaction was evaluated. Statistical Analysis Used: Collected data was analysed using repeated measures ANOVA and Independent t-test. Results: Intra-group comparison of ΔF values showed statistically significant improvement in ΔF value in all the four groups (P < 0.001, 0.002). Inter-group comparison of ΔF values based on intervention showed statistically significant fluorescence gain (P < 0.004) indicating resin infiltration intervention being better than remineralization in unstained grade III fluorosis. The colour difference was statistically significantly better with resin infiltration in both stained and unstained Grade III DF (P < 0.001). Conclusions: Resin infiltration intervention showed better fluorescence gain and colour masking compared to remineralization intervention.
