The role of polymorphism of the IL6 gene in tooth replantation.

The absence or presence of root resorption on the root surface of a replanted tooth indicates an immune-inflammatory reaction. Since interleukin-6 (IL-6) is considered an inflammatory marker in bone resorption, this study aimed to investigate the association between clinical variables and polymorphisms in IL6, with the outcome of replanted teeth at 1-year follow-up. Altogether, 127 avulsed teeth that were replanted and had their root canals treated were selected for this study.
