The early enamel lesions are reversible as it is a process involving mineral transactions between the teeth and saliva.

To evaluate the efficiency of three different tooth pastes on remineralization potential of initial enamel lesions using Vickers Micro hardness Test and Scanning electron microscopy.

Artificial carious lesions were prepared in human enamel with demineralizing solution. The treatment agents included were Colgate sensitive plus^® toothpaste, Regenerate enamel science™ toothpaste, BioRepair^® toothpaste and control as Deionized water. All the samples were subjected to treatment solutions as per the pH cycling model for 12 days to simulate the daily oral environment's acid challenge. The remineralization parameters-surface hardness and surface roughness of enamel blocks were evaluated with Vickers indenter and Scanning electron microscope respectively. Statistical Analysis: ANOVA test was used to check mean differences between the groups. Post hoc analysis was done using Tukey's post hoc test. SEM images were graded according to Bonetti et al grading criteria.

As per statistical analysis, maximum remineralization of enamel blocks occurred after applying Colgate Sensitive Plus^® tooth paste followed by BioRepair^® tooth paste and Regenerate enamel Science™ toothpaste. Least remineralization potential was shown by control group.

Colgate sensitive plus tooth paste with Pro Argin™ formula can be regarded as a potential remineralising agent. It can be concluded as a noninvasive means of managing early enamel carious lesions.
