Conclusion
Based on the results of this study, topical application of 75 ppm EGCG hydrogels to the tooth cavities with six hours of pulpal inflammation has the optimal result in reducing the expression of TNF-α and CGRP, but not of MDA.
Results
The T1 and T2 groups showed a significant decrease in TNF-α and CGRP expression compared to the control group, but there was no significant decrease in MDA in either group (P<0.05).
