Authors: Dr. Swapna Mahale, Dr. Alisha Panjwani et al. Aim: To evaluate the effects of different desensitizing dentifrices on dentinal tubule occlusion by scanning electron microscopy (SEM). Methods and materials: Thirty dentine blocks were prepared and divided into three groups of ten specimens each. The groups corresponded to the following treatments: Arginine, strontium chloride, and novamin.
The toothpaste was applied twice a day for fourteen days. The dentinal tubule occlusion was assessed using scanning electron microscope (SEM), at baseline i.e. before application of the toothpaste, at seven, and fourteen-day application, respectively. Results: Arginine and strontium chloride almost completely occluded the dentinal tubules at seven and fourteen day treatment as compared to novamin. Conclusion: As Arginine and Strontium chloride containing toothpaste occluded the dentinal…
