The Boost in Microinfiltration Technique with Sodium Hypochlorite
Moreira, Cátia Ribeiro / Rocha, Lígia / Costa, Sonia
45-year-old patient whose reason for consultation was to improve the appearance of the incisor teeth. The evaluation of the clinical history led to the following diagnosis: Dental Fluorosis. Prognosis: Favorable. Treatment plan: Microleakage (ICON®) and sodium hypochlorite (etch-bleach-seal technique).
In recent years, minimally invasive techniques, such as the microleakage technique, have been used to treat white spot lesions as an alternative to removing hard tissue with drills. The microleakage technique has been described as highly conservative in the treatment of non-cavitated white spot lesions. To improve this technique and decrease the need for regular composites at the end to smooth out the often cavity-surface, we have associated another lost-time technique such as sodium hypochlorite enamel bleaching, known in the literature as the ''Etch bleach and Seal'' technique. Whitening of hypomineralized enamel lesions using 5% sodium hypochlorite has been clinically applied and treatment using this approach has been successful in removing yellowish brown discolorations from lesions on young and permanent teeth.
Conclusions: With the correct use of these techniques, it was possible to considerably improve the appearance of the anterior teeth, as being the least possible invasive. It can be concluded that there are two safe techniques, favorable results in the treatment of white spots and yellowish discolorations. However, despite this excellent result, further literature is needed with greater follow-up on the use of these two techniques.
