Remineralization activities of toothpastes with and without aloe vera with different ratios of fluoride on demineralized enamel: An In-vitro study

Abstract

AIM and Background: The aim of this in-vitro  study was to evaluate and compare the efficacy of both pure aloe vera and commercially available toothpastes with different fluoride compounds and different fluoride amounts on artificial initial enamel lesions by Vicker's microhardness values. In the study, 72 extracted human molar teeth were divided into mesiodistal and 144 specimens were prepared using the vestibule and palatal/lingual surfaces of the teeth. After the surface treatments and initial microhardness measurements, all the specimens were placed in a demineralizing solution (pH: 4.5) for 7 days, resulting in artificial initial enamel lesion, and were randomly assigned to eight groups (n = 18). After the teeth were subjected to pH cycle for 14 days, microhardness measurements were repeated and the data were recorded. Materials and Methods: Statistical analyzes were performed using MedCalc Statistical Software version 12.7.7. The significance level was determined to be 0.05. Results: In the statistical results, when the microhardness values after demineralization and post-cycle were compared, Groups B1 and A2 showed the lowest values, while Groups A3 and B3 did not show a significant difference in terms of microhardness values after demineralization and post-cycle, and only Group B4 showed statistically significantly higher values. Conclusions: This study emphasized the remineralization effects of fluoride on initial enamel lesions. It can be said that toothpaste containing 1450 ppm fluoride and aloe vera provides an effective remineralization and sodium monofluorophosphate formulation may have a synergistic effect with aloe vera.
