“COMPARATIVE EVALUATION OF EFFECT ON DENTINAL TUBULE OCCLUSION BY THREE DIFFERENT DESENSITIZING DENTIFICES: A SEM STUDY”
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.
