摘要: This study was concerned with the relation between technical quality of root filling seal in teeth posts and radiographic status periapical tissues. Full-mouth series from 298 randomly chosen patients were examined by two observers. Endodontic treatment had been performed 852 roots observed 424 these. Periapical radiolucencies judged to be present 16% 13% without posts. Roots which remaining shorter than 3 mm showed a statistically significant higher frequency (p less 0.01). It found that an improper more unfavorable 0.05). The findings this indicate placement post will not per se decrease probability healing. also suggests must mm.
