Pain Control in Dentin Hypersensitivity in Patients With MIH

Pain Control in Dentin Hypersensitivity in Patients With MIH: Study Protocol for a Randomized, Controlled, Clinical Trial

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.

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.
