Evaluation Of Efficacy Of Arginine Calcium Carbonate Versus Potassium Nitrate Paste In The Treatment Of Dentinal Hypersensitivity

Abstract

Background and Aim:

Dentin hypersensitivity (DH) is a common oral health problem affecting one or more teeth of many adult individuals globally. It is characterized by a sharp pain which arises from exposed dentin in response to an external stimulus, and cannot be explained by any other form of dental pathology. Several agents and treatment modalities have been used in the treatment of this condition. The present study was conducted to compare the efficacy of arginine calcium carbonate paste (Test group) versus potassium nitrate (Control group) in the treatment of dentinal hypersensitivity.

Subjects and Methods: A total of 66 cases were randomly divided into two groups based on the toothpaste given: Test group - toothpaste containing 8% arginine and calcium carbonate, Control group - toothpaste containing 5% potassium nitrate. The patients’ DH scores for tactile stimuli was recorded on a visual analog scale and airblast  stimuli was recorded on a Schiff Cold Air Sensitivity scale at baseline, immediately post scaling after application of desensitizing paste, 1 month after  commencing the use of desensitizing paste, and 1 month following cessation of its use .

Statistical Analysis: The data was analyzed using Independent t test (P < 0.05).

Results: Both the toothpastes were effective in relieving dentinal hypersensitivity. However, toothpaste containing 8% arginine and calcium carbonate showed a better clinical response at the end of 2 months evaluation.

Conclusions: The desensitizing paste containing 8% arginine and calcium carbonate showed instant and long lasting reduction in the symptoms of DH.
