Sensitive Dentin

Molar-Incisor Hypomineralization (MIH) is a qualitative enamel defect caused by systemic hypomineralization that affects one to four first permanent molars, and may or may not involve incisors. The clinical repercussions associated with MIH can be characterized by: painful hypersensitivity, post-eruptive fractures, rapid progression of caries lesions in newly erupted first permanent molars, difficulty in achieving effective anesthesia, aesthetic impairments, and patient fear and anxiety. To date, there is no consensus on the best treatment for sensitivity in teeth with MIH, thus managing sensitivity in these teeth remains a significant challenge. The aim of this study is to evaluate the effectiveness of a 10% Biosilicate® solution as a desensitizing agent in MIH teeth in children, compared to Fluoride varnish (Duraphat® Colgate, Brazil). Children aged 6 to 12 years will be selected for this study, with a total of 63 participants diagnosed with MIH, and a sensitivity score ≥2 on the SCASS scale. The children will be randomly divided into two groups (n=21): GI: Duraphat®, GII: Biosilicate®. Interventions will be performed once a week for 4 consecutive weeks, followed by 8 weeks of follow-up. The results will be subjected to statistical tests with a 95% confidence level (α = 0.05).
