Comparative Clinical Evaluation of Three Different Agents in Reducing Dental Hypersensitivity in Periodontal Patients
Comparative Clinical Evaluation of Three Different Agents in Reducing Dental Hypersensitivity in Periodontal Patients
The present project will compare the effect of DH reduction using three different dentifrices
 (Sensodyne Repair and Protect - NOVAMIN technology; Dentalclean Daily Regenerator - REFIX
 technology; Dentalclean Daily Regenerator - REFIX technology + potassium citrate) in
 periodontal patients. The evaluation will be in 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. Profissional assessments and patient perception data will be performed.
Periodontal patients may report dentinal hypersensitivity (DH) caused by root surface
 exposure as part of disease process or as a result of periodontal treatment. Although some
 studies evaluated DH reduction using desensitizing toothpastes, no specific chemical/physical
 agent is reported for periodontal patients. Thus, the present project will compare the effect
 of DH reduction using three different dentifrices (Sensodyne Repair and Protect - NOVAMIN
 technology; Dentalclean Daily Regenerator - REFIX technology; Dentalclean Daily Regenerator -
 REFIX technology + potassium citrate) in periodontal patients. This randomized, parallel and
 blinded clinical trial will be divided into 3 groups (SEN GROUP: Sensodyne; REG GROUP:
 Regenerator; REGK GROUP: Regenerator + Potassium Citrate) 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 assessments
 (Schiff scale) and patient perception data on DH will be performed using visual analog scales
 (VAS). The comparison between treatment groups will be done by paired T-test if normal
 distribution is observed or Wilcoxon if non-normal distribution. The significance level
 adopted will be 5% (p <0.05).
Inclusion Criteria:

 -  patients diagnosed with periodontitis

 -  18 to 70 years old

 -  systemically healthy

 -  without any allergy to the dentifrices components

 -  patients who needed scaling and root planing procedures

 -  patients who had at least 2 teeth with DH (incisors, canines or premolars).

 Exclusion Criteria:

 -  pregnancy

 -  patients in orthodontic treatment

 -  patients with oral tumors, caries, fractured teeth, suspected endodontic involvement
 or excessive mobility;

 -  patients who used medication that could mask the painful sensation or who had used
 desensitizing agents in the last 3 months.
