HIF-1α, VEGF, and CD68 showed increased expression in PGs and RCs, suggesting an association between hypoxic conditions, enhanced angiogenic activity, and macrophage presence within the periapical inflammatory microenvironment. Future studies exploring HIF-1α and VEGF inhibitors as potential treatment modalities for periapical lesions are warranted.
Chatterjee et al. (Wed,) studied this question.
