The 4-week double-blind clinical trial to manage dentin hypersensitivity (DH) using different desensitizing toothpastes was conducted. 53 participants with DH were enrolled in this trial. The participants were randomized into 3 groups: Group N; no active ingredient-containing toothpaste (Pleasia fluoride-free), Group SC; a toothpaste containing strontium chloride (Sensodyne Original), and Group TP; a toothpaste containing tricalcium phosphate (Vussen S). They were instructed to brush their teeth manually for 3 min, 3 times per day for 4 weeks with the allocated toothpastes, and were assessed at baseline (0), 2, and 4 weeks, respectively. Schiff sensitivity score was recorded to 3 different stimuli (air-blast, cold, and acid) at each assessment. Overall DH was also assessed using a visual analog scale (VAS). The longer participants used the toothpastes, the greater reduction in DH in all groups to the three stimuli. Group TP demonstrated significant reduction of DH compared to group N for air-blast and cold stimuli. Group TP showed significantly lower VAS than group N and SC. Tricalcium phosphate containing toothpaste used in this trial was most useful to reduce DH. It can be one of the treatment options that alleviate DH.Dentin hypersensitivity (DH), referred to as the “common cold of dentistry,” is defined as short, sharp pain arising from the exposed dentin in response to thermal, evaporative, tactile, osmotic, or chemical stimuli that cannot be ascribed to any other form of dental defect or pathologyThe management of DH involves decreasing neural transmission and physically occluding dentinal tubules. Potassium nitrate (KNOStrontium ions have been studied as conventional active ingredients for DH relief since the 1960s and are the main active components of numerous desensitizing toothpastes. The effectiveness of the product in reducing DH appears to increase with repeated usagesThe objective of this prospective randomized clinical trial was to compare the DH-relieving efficacy of a toothpaste containing 19% (w/w) tricalcium phosphate (TP) with that of a positive control containing 10% (w/w) strontium chloride (SC) hexahydrate and a negative control toothpaste with no active ingredient against various stimuli (air, cold, or acid) using Schiff’s sensitivity score and visual analog scale (VAS).The null hypotheses tested were.The efficacy for relieving DH to air, cold, and acidic stimuli using Schiff’s sensitivity score does not differ significantly according to the type of toothpaste.The subjective VAS scores for DH the do not differ significantly between participants allocated different types of toothpastes.The duration of toothpastes use does not a significant affect DH relief.
