Investigation of Dentinal Tubule Occlusion by a Desensitizing Dentifrice: an in-Vitro Sem Analysis

The purpose of this study was to compare patent dentin tubules to in vitro dentin tubules in order to assess the dentin tubule occluding impact of a dentifrice incorporating Pro-Argin Technology (Colgate Sensitive Plus). Methods: The diameter of the dentine tubule was measured using scanning electron microscopy (SEM) on 20 produced dentin discs that were either left untreated or treated with the dentifrice. To evaluate tubule patency, microphotographs were obtained at a 2000x magnification. The dentifrice covered the treated sample, filling the dentinal tubule and decreasing or closing the tubule opening, according to SEM imaging results. Conclusion: According to pertinent statistical analysis, Pro-argin technology efficiently blocked dentinal tubules, making it suitable for use as a dental anti-sensitivity agent.
