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.

| 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. | Immediately after the intervention |
