Abstract

Background: White spot lesion is a demineralization process indicated by the increased of enamel microporosity. A tegillarca granosa shell contains 98.7% calcium and Vitis vinifera contains phytochemical compounds with fluoride, which has a potential to stimulate remineralization. Purpose: To analyze the Tegillarca granosa shell combination with Vitis vinifera and fluoride in decreasing enamel microporosity. Methods: The cream was prepared by combining 10% and 20% Tegillarca granosa shell with 10 grams of Vitis vinifera extract and 100 mg of fluoride. The cream was tested beforehand for viscocity and pH. Furthermore, 16 premolars were etched and divided into four groups. Group 1 was smeared with placebo (negative control) and Group 2 was smeared with casein phosphopeptide-amorphous calcium phosphate (positive control). The other groups were smeared with cream 10% (Group 3) and 20% (Group 4) Tegillarca granosa shell combination with Vitis vinifera and fluoride. Teeth were treated three times a day for 30 minutes and soaked in artificial saliva. After 14 days, the enamel microporosity was carried out using a scanning electron microscope. The data was analyzed with one-way analysis of variance (ANOVA) test followed by post-hoc least significant difference (LSD). Results: The enamel microporosity showed significant difference between Group 1 and the other groups. There was no significant difference between Groups 2, 3, and 4 (p<0.05). Although there was no significant difference between Group 3 and 4, the lowest one was in Group 4 (p>0.05). Conclusion: The cream, prepared by combining Tegillarca granosa shell with Vitis vinifera and fluoride, is effective in decreasing the enamel microporosity.

Abstract

Background: Glass ionomer cement (GIC) is widely recognized as the prevailing direct esthetic restorative material. In order for a restoration material to be considered effective, possess favorable physical and mechanical properties. Incorporating with hydroxyapatite (HA) can provide these properties. This research is to investigate the impact of integrating HA into GIC on the flexural strength and scanning electron microscopy (SEM) of the fractured surfaces. Methods: The study consisted of 28 samples of GIC, which are fabricated in the shape of rectangular prisms (25x2x2mm). The samples were divided into four groups n=7. Group 1 is a control group (GIC), Group 2 GIC+2%HA, group 3 GIC+2%HA, and GIC+4%HA. The flexural strength of the sample was evaluated by a Universal testing machine, followed by an examination of the fracture surface using SEM. Result: The Brown-Forsythe was used as data analysis to examine the flexural strength values across all groups, resulting in a statistically significant p-value of less than 0.05. The addition of HA does not result in a significant increase in the flexural strength value of the glass ionomer cement (GIC). The integration of microstructure based on scanning electron microscopy (SEM) pictures demonstrates improved visual quality following the incorporation of HA. Conclusion: The addition of HA to GIC did not result in a significant change in flexural strength compared to the control group. However, GIC group with 2% HA exhibited the highest average flexural strength value among all the groups
