Comparative Evaluation of Esthetic Improvement of Resin Infiltration (RI), In-office Bleaching (B), Enamel Microabrasion (M) and Resin Infiltration with Double Application of Infiltrant (2RI) on Non-pitted Fluorosis Stains: A Randomized Six-month Interventional Study

BACKGROUND: Newer minimally invasive treatment options for improvement in appearance of dental fluorosis stains are gaining popularity in recent years. OBJECTIVE: To evaluate and compare the clinical success in esthetic improvement of resin infiltration, in-office bleaching with 35% hydrogen peroxide, enamel microabrasion, and resin infiltration with double infiltrant application on nonpitted fluorosis stains. MATERIALS AND METHODS: Seventy two patients aged between 6 and 12 years with nonpitted dental fluorosis stains on the upper anterior teeth were randomly selected and divided into four interventional groups: group 1- resin infiltration (RI), group 2- in-office bleaching using 35% hydrogen peroxide (B), group 3- enamel microabrasion (M), and group 4- resin infiltration with double infiltrant application (2RI). In each group, standardized photographs were taken preoperatively, immediate postoperatively and after 1, 3, and 6 months time interval postoperatively to assess the esthetic improvement (EI) and changes in white/brown surface opacities/stains (SC) using a Visual Assessment Scale (VAS). RESULTS: RI and 2RI showed statistically significant results (p ≤0.05) followed by microabrasion and bleaching, for both the evaluation criteria (EI and SC) at all the follow-up intervals. CONCLUSION: Resin infiltration is a promising procedure that demonstrated remarkable clinical success for improvement in esthetics of nonpitted fluorosis stains with stable long-term positive outcome.
