| Abstract | ||||
| Purpose: The study was established to compare the remineralization effect ofnatural agents versus bioadhesive polymers with or without PH cycling using amicrohardness test. Materials and Methods: Forty extracted premolars were used.The roots of the teeth were removed, then the crowns of teeth were cut in mesiodistaldirection to expose the labial and lingual portion using a diamond disc so that 80specimens were obtained. Each tooth-half was fixed with superglue on the custom madeacrylic block. The enamel surfaces were polished to produce flat enamel surfaces. 80specimens were divided into four groups (A) according to the remineralizing agentused. Group A1 for eggshell nanoparticles, Group A2 for clove extract, and Group A3for carbopol, and Group A4 for carboxymethyl cellulose (20 each). Each group wassubdivided into two subgroups (10 each) according to PH cycling either with (B1) orwithout (B2). Then, the specimens were examined before and after demineralizationand after treatment agent with Digital Display Vicker Microhardness Tester.Results: The results showed that the highest microhardness mean values were foundwith eggshell nanoparticles followed by carbopol, and then carboxymethyle cellulosethen clove extract. Conclusion: Natural materials have remineralizing potentials andcould successfully replace synthetic products. | ||||
