IMPACT OF MEDICINAL PLANTS EXTRACTS ON MI VARNISH REMINERALIZING ABILITY ON PRIMARY TEETH: IN VITRO STUDY

Background: the objective of the study is to assess the effect of methanolic plant extracts on the remineralization ability of MI varnish on extracted primary teeth.Methods: An in vitro study was conducted on the crowns of 45 extracted primary teeth. A methanolic extraction was done for both clove and cinnamon and the treatment solution was obtained by using dimethyl sulfoxide solvent. The Vickers microhardness assessment was used to assess the hardness in different intervals. The teeth underwent demineralization to develop caries-like lesions and were then treated with MI varnish. The teeth were randomly divided into three equal groups Group A: MI varnish only, Group B: MI varnish + clove and cinnamon methanolic extract + solvent, and Group C: MI varnish + solvent. In the pH cycling the treatment was repeated each day for 10 days. Each group had a different treatment.Results: The intragroup comparison revealed that group A had the highest remineralization value (269.54±28.54), and group B had the lowest (263.82±15.73). There was a statistically significant difference between the MI varnish control group and the intervention group treated with methanolic plant extract (p=0.049).Conclusion: MI varnish alone was effective in increasing the microhardness. Adding the treatment with Clove and cinnamon methanolic extract diminishes the MI varnish remineralization potential.
