Evaluation of the Antibacterial Activity and the Remineralizing Potentiality of Two Natural Extracts and Their Mixture (In Vitro Study)

AIM: This study aimed to assess the antibacterial activity against cariogenic Streptococcus mutans (ATCC 25175) and commensal Actinomyces viscous (1300 EMCCN) oral bacteria determine remineralizing effect of previously demineralized bovine enamel lesion ginger extract, eggshell extract as well their mixture. METHODS: The two different extracts; were prepared mixture in an equal volume. Their S. A. was assessed by diffusion test clear zones diameters measurement (mm). Chlorhexidine Dimethyl sulfoxide solution utilized positive negative control, respectively. Thirty-six anterior teeth subjected artificial caries pH cycling regimen including alternate demineralization remineralization for 5 days. Then they randomly divided into three groups (G) (n = 12): G1: Ginger, G2: Eggshell, G3: Mixture. Specimens each group separately immersed 50 ml tested 12 h seven successive Vickers Microhardness Energy Dispersive X-ray (EDX) Analysis at baseline, after remineralization. RESULTS: Both extracts had profile growth mutants. However, showed highest statistically significant mean inhibition zone (mm), followed with no difference between them. Regarding efficacy; G1:(Ginger) microhardness G3:(Mixture) group, then treated specimens; which least values. EDIX analysis results, a increase F (wt%) both specimens. CONCLUSION: Ginger not only have but also strong ability enamel.
