Comparative assessment of enamel surface remineralisation with three different dentifrices: An energy dispersion x-ray spectroscopy analysis

Abstract

Comparative assessment of remineralisation of enamel surface when treated with three different dentifrices. Sixty-six extracted upper right first premolars were demineralized to form artificial white spot lesions. The samples were divided into 3 groups: Group 1-Biomin F, Group 2- Clinpro ToothCreme, Group 3- Amflor. They were treated with three different dentifrices (22/ group) for 14 days in simulated oral conditions. Energy dispersion X-Ray Spectroscopy was done pre and post remineralistaion. The primary evaluation parameter for this study was the Ca/P ratio. As per the results, the maximum increase in Ca/P ratio was seen in Group1, followed by Group 3 and 2 respectively. The results were found to be statistically significant. (p=0.045 i.e. p<0.05) The secondary evaluation parameter for this study was the change in Fluoride content. As per the results, the maximum increase in Fluoride content was seen in Group 2 which was followed by Group 3 which is equivalent to Group 1. However, the results were found to be statistically non-significant. (p=0.219 i.e. p>0.05) Biomin F has the highest remineralisation efficiency when compared to the other 2 dentifrices. Biomin F contains an optimum combination of fluoride (600 ppm), phosphate and calcium ions, incorporated within the structure of the glass itself. The glass gradually dissolves over up to 12 hours neutralizing acids in the mouth and deposit fluorapatite. Thus, it can be used in patients undergoing orthodontic treatment to prevent or reduce the formation of white spot lesions.
