Observation on efficacy of endodontically treated teeth supported by fiber posts-cores

Objective: To discuss the effect of of endodontically treated teeth supported by fiber posts-cores. Methods: 168 residual teeth of 112 patients were endodontically treated, their periodontal tissue were heathy and their roots were long enough. Among them wear type wedge shape defencts were teeth 10 star, adjacent surface defent 7 star due to special reason not to do crown and a residual roots and residual crowns reppair form post-core crown in 144 cases. Results: After two years, 161 teeth were succeeded and 7 teeth were failed. Among failed teeth lingual restorative of one tooth was cast; dentine of two teeth were broken and fiber posts-cores were good; cervical hard tissues of 3 teeth were broken; fiber post of one tooth drop and root were good. Successful rate of restoring was 95.8%, fiber posts-cores crown was 97.1%, fiber posts-cores was 88.8%.
