Study: NCT04268238

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: Hygiene Guidance
Description: Two weeks before the start of the study, the volunteers will go through a wash out period, where they should only use oral care products donated by the researchers, which should be used until the end of the study. The oral hygiene kit will contain 1 toothbrush (Professional Lab Series, Colgate Palmolive), 1 toothpaste without desensitizing agent, but with fluorine (Elmex) and 1 dental floss (Colgate).

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: Sealant Application
Description: Permaseal (Ultradent) is an unloaded resin based on methacrylate and photopolymerizable. The teeth that will be sealed will be isolated. 35% phosphoric acid will be applied for 20 seconds and then it will be necessary to wash and dry the tooth surface. Apply a thin layer of PermaSeal for 5 seconds to the tooth surface and light curing for 20 seconds. After that, it is necessary to evaluate occlusion.

Intervention type: RADIATION
Group type: EXPERIMENTAL
Intervention: Low Level Laser Application
Description: Volunteers will receive irradiation with AsGaAl laser, wavelength of 780nm (Laser XT Therapy, DMC, São Carlos, SP) with fixed power of 100mW, density of energy of 35 J/cm2 (considering a spot size of 0.028cm2 of this equipment), the dose will be 1 J per point. Irradiation will be performed at a cervical, an apical point, and another point exactly on the injury, totaling a dose of 3J. Treatment should be performed in 3 sessions with an ideal 72-hour interval between them.
