Efficacy of Remineralizing Potential of β-Tricalcium Phosphate Nanoparticles Versus Functionalizedβ-Tricalcium Phosphate Nanoparticles

The study involves collecting Sixty non carious sound human permanent premolars from an outpatient clinic at Tanta University's maxillofacial surgery department. The teeth are selected for their absence of caries, hypocalcification restoration, fracture fluorosis, and cracks. The teeth are cleaned and prepared for the study, including demineralization and artificial incipient enamel carious lesion preparation. The teeth are randomly assigned into four groups: functionalized Nano ᵦ tricalcium phosphate particles, Nano ᵦ tricalcium phosphate particles, sodium fluoride mouth wash, and artificial saliva. The pH of all groups is adjusted at 7. The specimens are treated in a daily pH cycling regime, with daily solution replacements. The specimens are then dried and analyzed using an Energy Dispersive X-Ray (EDX) analysis scanning electron microscope. The element content distribution of calcium and phosphorus elements is measured, and the specimens are evaluated at base line, after demineralization, and after 2, 4, and 6 weeks. Surface micro-hardness is determined using a Digital Display Vickers Micro-hardness Tester.

Data will be collected, presented, and statistically analyzed using SPSS software package system using ANOVA at a significance level of 0.05.
