Hypomineralization Molar Incisor clinical trials

Photobiomodulation and Glass Ionomer Sealant as Complementary Treatment for Hypersensitivity in Molars With MIH

Photobiomodulation has been widely used as complementary treatment for dentin hypersensitivity, with reports of clinical success. However, the literature offers only one study in which photobiomodulation was used for the treatment of sensitivity in molars with molar incisor hypomineralization (MIH). The aim of the proposed study is to determine whether photobiomodulation enhances the results of treatment with glass ionomer sealant on molars with MIH that present sensitivity. Methods and analysis: The study involving 50 patients 6 to 12 years of age tha will be randomly allocated in two groups. Group 1 (control group) (n = 25): toothpaste with a concentration of fluoride, glass ionomer sealant and sham low-level laser (LLL) and Group 2 (n = 25): toothpaste with a concentration of fluoride, glass ionomer sealant and active low-level laser (LLL). The evaluations will involve MIH record, Simplified Oral Hygiene Index (OHI), Schiff Cold Air Sensitivity Scale (SCASS) and Visual analog scale (VAS) before the procedure. Immediately after the procedure hypersensitivity index (SCASS/VAS) will be register. Record of OHI and SCASS/VAS will be register 48 horas after and as well as 01 month after the procedure. It is expected that by the second consultation a decrease in sensitivity will be observed due to the treatments received in the two groups.
