“Comparative Evaluation of Effect on Dentinal Tubule Occlusion by Three Different Desensitizing Dentifices: A Sem Study”

Abstract

Introduction: Dentine hypersensitivity (DH) occurs on exposed dentine and is dependent on the patency of dentinal tubules. This study compared the effectiveness of toothpaste containing Strontium Chloride, Novamine, Pro-Arginine in occluding dentine tubules along with comparision of those.
 Materials and Method: 45 freshly extracted teeth were randomly divided (15 each) into 3 groups:
 Group 1 15 Teeth treated with toothpaste containing Strontium Chloride.
 Group 2 15 Teeth treated with toothpaste containing Novamine
 Group 3 15 Teeth treated with toothpaste containing Pro-Arginine.
 Each specimen was brushed with the dentifrice slurries and examined under SCM.
 Result: The mean of occluded dentinal tubules on the dentin surface after brushing with three dentifrices were significant among them Pro-arginine group showed maximum occlusion.
 Conclusion: The present in vitro SEM study results revealed that: All the experimental agents– Strontium chloride, novamin, Pro- Argenine were effective in occluding dentinal tubules & the percentage (%) of occluded tubules was found to be highest for Pro- Argenine as compared to the other groups.
