Long-term outcomes of primary molar ferric sulfate pulpotomy and root canal therapy

摘要: Purpose The purpose of this study was to compare long-term outcomes of ferric sulfate pulpotomy (FS) and primary tooth root canal therapy (RCT) in vital pulps of deciduous molars exposed to caries lesions. Methods A total of 291 molars were treated in 130 children. One hundred and eighty-two molars received FS and 109 received RCT by random selection. Results At 3-year re-assessment, 29 molars (15 FS, 14 RCT) were available for clinical and radiographic examination. Two independent pediatric dentists evaluated periapical radiographs of the treated molars. Molars were classified 1 of 4 outcomes: (1) N=normal treated molar; (2) H=nonpathologic radiographic change present; (3) PO=pathologic change present, follow-up in 6 months; (4) PX=pathologic change present extract immediately. Survival analysis was applied. A good level of agreement between raters was found for molars with outcome PX(=0 …
