Infiltrating Resins, Noninvasive Treatment of White Spot Lesions: A Case Report

A bstrAct Demineralization of tooth enamel causes milky, opaque white-spot lesions (WSL). Aim: The aim was to use infiltrating resin as a noninvasive technique on the removal of WSL. Case description: An 18-year-old female patient presented to a dental consultation complaining about “the spots in her front teeth”; the patient had recently finished her orthodontic treatment. The clinical examination identified WSL on the vestibular surfaces of teeth 11, 21, and 22. A minimally invasive treatment was selected with infiltrating resin (ICON Smooth surface, DGM, Germany). After absolute isolation of the upper anterior sector, the teeth with the WSL were conditioned with 15% hydrochloric acid for 2 minutes and rinsed with abundant profuse water for 30 seconds. Ethanol was applied for 30 seconds and volatilized with oil-free air for 20 seconds. The infiltrating resin was placed and left to act for 3 minutes to allow infiltration in the previously etched area. The excess resin was removed, and light cured for 40 seconds with a LED light-curing lamp (Bluephase N® MC, Ivoclar Vivadent, 800 mW/cm 2 , 430–490 nm). Conclusion: The WSL were successfully removed, stopping the demineralization process. The use of infiltrating resins is an excellent noninvasive treatment to eliminate WPL timely with excellent clinical results. Clinical significance: One of the challenges in dental esthetics are visible WSL in the anterior region. Considering the minimally invasive treatments, the use of infiltrating resins is indicated to treat these WSL, as an indication of an initial caries or certain degrees of fluorosis.
