Comparative Efficacy Of Diode Laser Vs Iontophoresis Along With Desensitizing Agent In The Treatment Of Dentinal Hypersensitivity: A Randomized Clinical Trial

Aims: The aim of this randomized clinical trial was to evaluate and compare the clinical efficacy of diode laser using with topical Potassium nitrate (KNO3) gel and Iontophoresis with NaF gel in the treatment of dentinal Hypersensitivity. Methods and Material: 20 systemically healthy patients with Dentinal Hypersensitivity were enrolled in the randomized clinical trial. The patients with dentinal hypersensitivity were randomly allocated into 2 groups: Group I was treated with diode laser and KNO3 gel; Group II with Iontophoresis unit. Sensitivity was recorded using the verbal rating scale before treatment, 10 min after treatment and 7, 15 and 21 days post therapy. Statistical analysis used: The statistical analysis was carried out using Descriptive Statistics at different times between the Groups. The data were entered in Microsoft Excel and analyzed using statistical package for social science (SPSS) version 22 software. The results were averaged (mean ± standard deviation) for continuous data. P < 0.05 was considered as statistically significant. Results: After 10 min ,7th day and 15th day, levels of hypersensitivity were statistically significant among both groups. Conclusions: The present study concluded that Diode Lasers associated with 5%KNO3 topical gel showed significantly greater reduction of DH than Iontophoresis unit.
