Pain Control in Dentin Hypersensitivity in Patients With MIH

University of Nove de Julho140 enrolled

Overview

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.

Hygiene GuidancePROCEDURE

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).

Sealant ApplicationPROCEDURE

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.

Inclusion Criteria: * Be between 18 and 35 years old; * Present good general health; * Present at least one tooth with dentin hypersensitivity reported in the cervical region, which must have a graduated sensitivity equal to or greater than 4 in the VAS scale. Exclusion Criteria: * Present active caries lesions or restoration defects in the tooth to be analyzed; * Present sufficient dentin loss that requires restorative treatment or periodontal surgery; * Volunteers who underwent any professional desensitizer treatment in the last 6 months; * Volunteers who used desensitizing pastes in the 3 months; * Volunteers who were using anti-inflammatory or analgesic drugs at the time of recruitment; * Volunteers who are pregnant or breastfeeding.

Outcomes

Primary Outcomes

Change in Pain Evaluated by a Visual Analog Scale (VAS)

Pain will be assessed with the visual analogue scale (Visual Analogue Scale - VAS), after stimulation with air from the triple syringe and an explorer probe.

Time frame: Baseline, immediately after treatment, 1 week, 1, 3 and 6 months after treatment.
