Abstract

Aim and objective:The aim of this research is to analyze the effect of calcium hydroxide combinations with green tea extract and the combination of calcium hydroxide with cocoa pod husk extract on the activation of p38 MAPK and wide area of reparative dentin in mice dental. Materials and methods: This study used 36 rats that were randomly divided into three treatment groups: positive control group was applied calcium hydroxide and aquades (group I), the test group was applied calcium hydroxide combined with cocoa pod husk extract (group II), and the next test group was applied using calcium hydroxide combined with green tea extract (group III); all the cavities were restored with RMGIC. On day 7 and 28, experimental animals from each treatment group were killed by peritoneal injection to see the activation of p38 MAPK, while reparative dentin was only seen on day 28. Results: The result of data analysis using Multiple Comparison Tukey HSD test showed significant difference between the positive control group and the test groups for the average p38 MAPK activation value on day 7 and 28. But there was no significant difference between two test groups. The same thing was obtained in the calculation of the average area of reparative dentin, where group I had the lowest value compared to groups II and III on day 28 with a significant difference. There was no significant difference between groups II and III. Conclusion: The use of combination calcium hydroxide with green tea extract and combination calcium hydroxide with cocoa pod husk extract have significant effect on p38 MAPK activation and wide area of reparative dentin in mice dental. Clinical significance: The use of combination calcium hydroxide with green tea extract and combination calcium hydroxide with cocoa pod husk extract have been proven to activate more p38 and form a wider reparative dentin
