Summary

This study aims to evaluate the effectiveness of different protocols in controlling dentin hypersensitivity in patients with teeth affected by MIH. The subjects will be randomly designated in four experimental groups, according to different treatments. Pain will be assessed with the visual analog scale (Visual Analogue Scale - VAS), after stimulation with air from the triple syringe and and an exploratory probe at the time of (initial) recruitment, immediately after treatment, after 1 week and 1 month, 3 and 6 months after treatment.

Conditions

  • Hypersensitivity Dentin

Interventions

PROCEDURE

Hygiene Guidance

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).

PROCEDURE

Sealant Application

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.

RADIATION

Low Level Laser Application

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.
