[Application status and prospect of single-cone obturation technique with bioceramic sealers].

Compared with cold lateral condensation and continuous wave of condensation which are classically used in clinical, newly emerging single-cone obturation technique is easy-to-operate as well as time-saving. Especially when combined with bioceramic root canal sealers of improved physicochemical and biological properties, single-cone obturation technique showed satisfactory short-term outcomes in clinical observations. However, difficulties still exist in avoiding the root canal overfilling and in operating the retreatment. Besides, the long-term effects of single-cone obturation with bioceramic sealers still remain unclear. This article makes an overview on the history and development of single-cone obturation ,and provides analysis of its pros and corns. Furthermore, we would also like to summarize its clinical application and look into its future improvements.冷侧压充填技术和热牙胶连续波充填技术是临床经典的根管充填方法。单尖法根管充填技术具有操作简便省时的特点，近年来结合具有优良理化和生物学性能的生物陶瓷根管封闭剂，取得了较好的短期临床效果。但目前针对生物陶瓷封闭剂单尖充填后根管超填、根管再治疗困难，以及长期临床疗效不明确等情况尚缺乏合理的规避及解决办法。本文回顾单尖法根管充填的起源与发展，解析其优缺点和临床应用现状，并对该技术的改良及临床应用前景进行展望。.
