Brief Summary

This randomized, placebo-controlled, triple-blind trial aims to evaluate the effect of glutaraldehyde associated or not with 37% phosphoric acid conditioning on dentin hypersensitivity reduction after non-surgical periodontal treatment, and its durability after 15 and 30 days. desensitizing treatment. Additionally, investigate the impact of these treatments on health-related quality of life. The investigators selected patients who, after scraping and planing procedures, presented at least 2 teeth meeting the following inclusion criteria: presence of gingival recession without or with a periodontal pocket up to 5mm probing depth, which presented painful sensitivity response to tactile stimulus. and evaporative. Subjects were randomized into 3 groups: Placebo Group (GP) - Placebo Gel application followed by Placebo solution (distilled water); GPG- Placebo Gel application followed by application 5% aqueous glutaraldehyde solution; GSG - Application of 37% phosphoric acid followed by 5% aqueous glutaraldehyde solution. The sensitivity of the dental elements was evaluated by pain stimuli (tactile and evaporative) with the aid of a Visual Analog Scale (VAS). A questionnaire was applied to patients with the objective of capturing psychosocial experiences, prior to treatment and one month after its completion, to assess the impact of desensitizing treatment on health-related quality of life. Data will be collected and appropriate statistical tests will be applied.

Outcome Measures

Primary Outcomes (1)

  • Dentin sensitivity

    Evaluation of pain (dentin sensitivity) by applying tactile (exploratory probe pressure) and evaporative (air blast) stimuli on exposed dentin. Sensitivity will be measured using the Thomas Schiff scale from 0 to 3. Zero means absent dentin sensitivity and three means severe dentin sensitivity.

Secondary Outcomes (1)

  • Dentin hypersensitivity experience questionnaire
