Purpose: This study aimed to compare the anti-collagenolytic effect of Green tea, Aloe vera and chlorhexidine on artificial erosion in human dentin using microhardness test and environmental scanning electron microscope (ESEM). Materials and Methods: For this study, 60 extracted sound human maxillary premolars were subjected to artificial erosion and randomly divided into three equal groups (20 premolars each) according to immersion in the tested anti-collagenolytic agents; group (A1) Green tea, (A2) Aloe vera and group (A3) Chlorhexidine (CHX). The microhardness analysis and (ESEM) photomicrographs were taken for the surface of dentin specimens three times, at base line, after the artificial erosion and after immersion in each treatment solution. Bonferroni’s post-hoc test was used for pair-wise comparisons. Statistical analysis was performed with IBM SPSS Statistics for Windows. Results: Results showed no statistically significant difference in microhardness mean values between Aloe vera and (CHX), However, both showed statistically significant increase in microhardness values than Green tea. These results were also supported by (ESEM) photomicrographs. Conclusion: Chemical gold standard CHX could be substituted by natural safe herbal sources and hence Aloe vera opens a new perspective in management of dental erosion.
