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).

Professional evaluation of Dentin Hypersensitivity
Air blast sensitivity evaluated by an experienced dentist (Schiff scale) Score 0 = Tooth/Subject does not show sensitivity in response to air stimulation; 1 = Tooth/Subject responds to air stimulus, but does not request discontinuation of stimulus; 2 = Tooth/Subject responds to air stimulus, and requests discontinuation or moves from stimulus; 3 = Tooth/Subject responds to stimulus, considers stimulus to be painful, and requests discontinuation of the stimulus.
Time frame: T1- immediately before scaling and root planing procedures (SRP)

Patient's perception of DH
Patient's perception of DH was also evaluated with visual analogue scale (VAS), being 0 without any painful sensation and 100 the most painful scenario.
