title: Comparative evaluation of diode laser, stannous fluoride gel, and potassium nitrate gel in the treatment of dentinal hypersensitivity.
abstract: The aim of the present study was to compare the efficacy of diode laser (DL) with stannous fluoride and potassium nitrate gels in the treatment of dentinal hypersensitivity (DH). Fifty-four subjects, ages 25-45, having 2 adjacent teeth sensitive to air blast stimulation were included. The subjects were divided randomly into 3 groups (n= 18): Group A, subjects treated with DL; Group B, subjects treated with 0.4% stannous fluoride gel; and Group C, subjects treated with 5% potassium nitrate gel. Each group was evaluated at baseline; at weekly intervals for 2 consecutive weeks; and at 1, 3, and 6 months. All 3 groups showed decreases in the DH scores between baseline and 6 months This was more pronounced in Group A at all time intervals. When the 3 groups were compared between baseline and Week 1, there was a statistically significant decrease across all 3 groups between (P = 0.0020). The greatest difference in the DH scores between baseline and Week 1 was in Group A, compared to Groups B and C. The 940 nm DL was not only efficacious, but also brought about improved immediate relief as compared to stannous fluoride and potassium nitrate gels in the reduction of DH.
