Blocking Tubules Technologies for Periodontal Patients Dentin Hipersensitivity - Preliminary Results
Objectives: Periodontal patients may report dentinal hypersensitivity (DH) caused by root surface exposure as part of disease process or as a result of periodontal treatment. Blocking tubules technologies contained on toothpastes are one of the most effective tooth pain relief products used on daily application, but no specific chemical/physical agent is reported for periodontal patients. Thus, the present preliminary, randomized, blind and parallel clinical trial compared the effect of three different technologies (NovaMin, REFIX and REFIX enriched with potassium salt) for reduction of DH in periodontal patients.
Methods: Patients were randomly divided in groups: SEN- Sensodyne Repair and Protect - NOVAMIN technology; REG- Dentalclean Daily Regenerator - REFIX technology; REGP -Dentalclean Daily Regenerator - REFIX technology + potassium citrate. Periodontal patients with at least 2 teeth presenting DH were included and evaluated at 6 moments: T1 and T2- immediately before and after scaling and root planing (SRP) procedures; T3-after polishing sensitive areas with rubbers cups and the dentifrice determined for each group of patients and T4, 5, 6- After 2, 4 and 8 weeks of SRP. Air blast sensitivity evaluation by an experienced dentist (Schiff scale) and patients’ perception of DH using visual analog scales (VAS) were performed. Data were analyzed by two way repeated measures ANOVA complemented by Tukey test with significance level of 5% (p <0.05).
Results: Preliminary outcomes evaluated by dentist and patients demonstrated that SEN, REG and REGP reduced DH in periodontal patients (n=18) without statistical difference between groups. All patients initially presented moderate to severe pain (64.3) and after treatments reported mild pain (21.3). Similarly, dentist evaluation showed significant reduction in DH with the use of three technologies (2.26 to 0.56). According to VAS data, SEN and REG presented DH reduction on T4, T5 and T6 compared to T1 (p<0.05). REGP presented statistical difference on T6 compared to T1. Based on dentist evaluation, the three technologies presented DH reduction after T4 (p<0.05).
Conclusions: According to these preliminary outcomes, the three different technologies reduced DH in periodontal patients.
