Abstract (original English)
This study investigated the influence of ethylenediaminetetraacetic acid (EDTA) irrigation on cementum-like tissue formation and TGF-β1, FGF-2, and VEGF immunolabeling during regenerative endodontic procedures (REPs) in immature rat molars. The lower first molars of 12 four-week-old male rats (80 g) underwent pulpectomy in the mesial canal and were randomly categorized into two experimental groups (n = 6): sodium hypochlorite (NaOCl) - irrigated for 5 min with 2.5% NaOCl; and NaOCl-EDTA - irrigated with 2.5% NaOCl, followed by 5 min of 17% EDTA. After inducing bleeding with a size 10 K-file, the cavities were sealed. Untreated molars served as control-15d (n = 3) and immediate control (n = 3). Either immediately or after 15 days, the animals were euthanized, and the teeth were collected for histomorphometric and immunohistochemical (TGF-β1, FGF-2, and VEGF) analysis. The results were analyzed by the Mann-Whitney U-test (p 0.05). In conclusion, the use of EDTA in REPs positively affected the formation of cementum-like tissue and TGF-β1 and VEGF in the apical region but did not influence FGF-2.
What this study does not prove
