The efficacy of 8% Arginine-CaCO3 applications on dentine hypersensitivity following periodontal therapy: a clinical and scanning electron microscopic study

subject

description

Objectives: Periodontal therapy is one of the etiological factors of dentine hypersensitivity (DH). This study aimed to evaluate the efficacy of %8Arginine-CaCO3 on DH that affects patients after periodontal treatment. Study design: Seventy-one teeth from the volunteers (n=36) with history of DH caused by periodontal therapy were included in this study, and randomly divided into two groups: group-1, who received 8%Arginine-CaCO3 and group-2, who received 1.23%NaF-gel. The clinical indices were recorded at first visit.DH was evaluated by using tactile, air-blast, and thermal stimuli. The subject’s response was recorded at baseline, immediately (Day-0) and one month after the application. Results and conclusions: The results were statistically analyzed, and it was found that 8% Arginine-CaCO3 treatment was more effective than 1.23% NaF-gel at time intervals. Sensitivity score differences between the groups were statistically significant at Day-28. The 8% Arginine-CaCO3 group exhibited statistically significant reduction in DH on three stimuli at baseline to Day-28. It was concluded that 8% Arginine-CaCO3 is more effective than 1.23% NaF-gel in reduction of patients’ pain.
