Comparative Evaluation of Commercially Available of Three Desensitizing Toothpaste On Dentinal Tubule Occlusion- An In-vitro SEM Study

Dentinal hypersensitivity is a common complaint among patients. The acute, non-spontaneous, short or long lasting nature of pain requires a therapeutic mode which would bring about a significant immediate and lasting relief from dentine hypersensitivity. This study compared the efficacy of three commercially available in occluding dentinal tubules using Scanning electron microscopy. A total of 20 dentin blocks were obtained from the roots of the single rooted teeth  and randomly divided into three groups comprising of three test groups. The dentinal occlusion are evaluated using scanning electron microscopy (SEM). All groups showed an increase in the percentage of tubular occlusion at However pro-argin group showed a significantly greater percentage of tubular occlusion as compared to the other groups after seven days. All the experimental agents were effective in occluding dentinal tubules as compared to the control group. The percentage (%) of occluded tubules was found to be highest for pro-argin as compared to the other groups over a period of 7 days. However further long term studies more studies are required to come to a conclusion.
