乳牙盖髓剂MTA与新型生物材料Biodentine的比较

Comparison of Biodentine and MTA as Pulpotomy Agents for Primary Teeth

目前,牙髓切断术是最常见的乳牙牙髓治疗方法之一,该治疗方法在严格无菌条件下,去除冠部感染牙髓并用盖髓剂覆盖于健康牙髓断面上,达到保留健康活髓的目的。尽管矿物质三氧化物聚集体(MTA)是乳牙牙髓切断术的常用盖髓剂,但其仍有许多缺点。近年出现的新型硅酸钙材料Biodentine(BD)有着优良的机械性能、生物相容性和较好的临床疗效,有望成为MTA的替代品。本文比较了BD和MTA作为盖髓剂的各方面性能及临床疗效等,从而探讨新型材料BD作为乳牙牙髓切断术盖髓剂的应用前景。

Pulpotomy is one of the most common therapies of primary teeth.The pulpotomy technique involves a series of sterile procedures including removal of the infected pulp and covering the remaining pulp with a pulp-capping agent.Mineral trioxide aggregate(MTA)is now commonly used as pulp-capping agent for pulpotomies in primary teeth,but it still has many disadvantages.Biodentine(BD),a new-developed calcium silicate cement with superior mechanical property,biocompatibility,and excellent clinical effect,is a promising alternative to MTA.In this review,we list and compare the characteristics and clinical efficacy of MTA with BD as pulpotomy agents for primary teeth.
