Reduction Of Dentine Hypersensitivity By Strontium Acetate : Clinical Trial

Method: 44 volunteers were divided into 2 groups. The first group was introduced to brush their teeth with Strontium acetate containing tooth paste and the second group was introduced to brush their teeth with Fluoride containing tooth paste twice a day. They were recalled for estimated hypersensitivity score 2, 4 and 8 week after using toothpaste. Visual analog score (VAS score) was used to recorded hypersensitivity score after applying tactile force and dental unit air stimulation and then estimated personal perception. Kruskal Willist’s test was use to statistic analysis.

Result: This study shown that strontium acetate containing tooth paste significantly reduce sensitivity score at week 2, 4 and 8 when use tactile stimulation and volunteer’s personal perception compared to baseline visit (p<0.05), for dental unit air stimulation Strontium acetate containing tooth paste reduce sensitivity score at week 4 and 8 compared with baseline visit significantly (p<0.05). Strontium acetate containing tooth paste reduce sensitivity score more than Fluoride containing tooth paste at week 2, 4 and 8 for all stimulation (p<0.05).

Conclusion: Our data shown that Strontium acetate containing tooth paste can reduce sensitivity score more than fluoride containing tooth paste for all stimulation.
