Abstract

Background: Pulpitis can occur because the deep cavity preparation and it causes increasing of NO levels. Perforated teeth require direct pulp capping (DPC) treatment. The current standard DPC material is calcium hydroxide. However, several studies have found weaknesses of calcium hydroxide that can affect the success of DPC treatment and new, more biocompatible materials are needed. Epigallocatechin-3-gallate (EGCG) in green tea has many benefits, including antioxidant, anticolagenase, anticancer, anti-inflammatory and has the ability of radical scavenging to clean NO so that pulp healing can occur better by increasing the number of fibroblast cells that play a role in wound healing. Purpose: To determine the concentration of hydrogel EGCGs that are effective in increasing the number of fibroblast cell proliferation in the dental pulp perforation of Wistar rats. Method: This research is a laboratory experimental study with a randomized post test only control group design. Samples used in the study were 24 male Wistar rats which were divided into four groups, namely the negative control group and the treatment group were given EGCG 60 ppm, 90 ppm, and 120 ppm and were decapitated on the 7th day after treatment. The maxilla and the 1st molar were taken and decalcified, to process the HPA reading with HE staining. Observations were made using a microscope with a magnification of 400x. Results: There were significant differences in the treatment groups with 60 ppm and 90 ppm hydrogel hydrogels on the results of the Oneway ANOVA difference test (p <0.05). Conclusion: The concentration of hydrogel EGCG which is effective in increasing fibroblast cell proliferation is 90 ppm.

Abstract

Background: Pulpitis is an inflammatory pulp that can occur due to mechanical trauma that causes perforation of the pulp. Treatment of pulpitis Emergency frequently using Eugenol. High concentrations of Eugenol have a cytotoxic effect that causes local necrosis and inhibits the recovery process. An alternative consideration with Epigallocatechin 3-gallate (EGCG) which has good antioxidant properties and increases the complexity of inflammation by inhibiting the production of inducible nitric oxide synthase (iNOS) and nitric oxide so that levels migration of inflammatory cells to the area of injury will decrease and inflammation will occur shorter then initiates the proliferation so the recovery process and tissue repair will be more rapidly occurring. One of the cells that support tissue repair is macrophages. Purpose: this study aims to explain the effect of EGCG on the number of macrophage cells in pulp inflammation with mechanical injury. Methods: The study used 24 Wistar rats teeth divided into four groups, namely control (C), and 3 treatment groups T1, T2, and T3. Each group consisted of 6 rats prepared, then T1 was named EGCG hydrogel 60 ppm, T2 was given EGCG hydrogel 90 ppm, while T3 was given EGCG hydrogel 120 ppm. On the 3rd day, Wistar rats were decapitated to continue making HPA preparations. Results:This study showed a significant difference in each group (p< 0.05) using One-Way Anova analysis. Conclusion: EGCG hydrogel 90 ppm  is effectivein increasing the number of macrophage cells.
