Mineral trioxide aggregate produces superior outcomes in vital primary molar pulpotomy.

摘要: PURPOSE The purpose of this study was to investigate the outcomes vital primary molar pulpotomy when there is no direct contact between eugenol and pulp. Four techniques were compared: (1) ferric sulfate (FS) pulpotomy; (2) eugenol-free FS (3) mineral trioxide aggregate (MTA) (4) FS/MTA pulpotomy. METHODS technique assigned each determined by random selection. Two blinded, disinterested raters classified into 1 3 radiographic outcomes: N=normal without pathologic change; Po=pathologic change present, follow-up recommended; Px=pathologic extract. RESULTS A total 92 patients with 227 pulpotomy-treated molars returned for at least recall examination. Median 24 months (range=12-38 months). MTA demonstrated significantly fewer Px than (P=.002, chi-square test). Eugenol-free more (P<.001, test) or molars. Significantly lower survival compared (P=.02, log-rank over 6 38 months. CONCLUSIONS Outcomes superior after a median 2 years.
