title: The leakage resistance of endodontic fiber obturators.
abstract: Fiber obturators have been introduced into endodontics but few reports exist regarding their efficacy compared to standard obturation materials. This study evaluated the leakage resistance of fiber obturators compared with other obturation materials. All specimens showed a progressive increase in leakage with time. The data indicate that fiber obturation and a new cone/sealer system provide the best canal obturation as evidenced by the leakage behavior.
