Abstract

This study aimed to evaluate the efficacy of diode laser combined with two in-office desensitizing agents 8% Arginine-CaCO3 and 1.23 NaF varnish on reducing dentine hypersensitivity (DH) in periodontitis patients.
Materials and Methods: Forty patients having stage I and Stage II periodontitis were selected according to the criteria of AAP (2017) with complaint of (DH) after routine periodontal therapy . Patients were randomly divided into two groups: group1- received NaF varnish then diode laser application at 1 W (PW) ,(CW) for 30 seconds using 320µ fiber. Group-2, treated with 8%Arginine-CaCO3 plus same laser irradiation. Each tooth received three application Dentine hypersensitivity evaluation was by tactile, air-blast, and thermal stimuli and measured using VAS scores. The patient’s response was recorded at baseline, one month and 3 month after the application.
Results and conclusions: The results were statistically analyzed, and it was found that 8% Arginine-CaCO3 plus laser treatment was more effective than 1.23% NaF-varnish plus laser at time intervals. Sensitivity score differences between the groups were statistically significant at one and three months. The 8% Arginine-CaCO3 group exhibited statistically significant reduction in dentine hypersensitivity on three stimuli at baseline to one and three months. It was concluded that 8% Arginine- CaCO3 plus laser irradiation is more effective than 1.23% NaF varnish plus laser irradiation in reduction of patients’ pain in periodontitis patients.
