[Advances in root canal filling materials used in primary teeth].

Root canal treatment of primary teeth is the most common treatment method for pulpitis and periapical periodontitis in pediatric dentistry. Effective root canal treatment could prevent the teeth from occurring of periapical infection or promote the healing of periapical lesions of teeth with periodontitis for preserving the decayed tooth, preventing early loss of primary teeth and inducing the formation of normal permanent dentition. The material selection for root canal filling is one of the most important factors influencing the treatment outcome of root canal treatment. So far, there has been various root canal filling materials used in clinic. This paper summarized the characteristics and clinical applications of currently used root canal filling materials in treatment of primary teeth.乳牙根管治疗术是治疗乳牙牙髓炎和根尖周炎最常用的方法。有效的根管治疗能防止发生根尖周病或促进根尖周组织愈合，从而保留患牙，避免乳牙早失，诱导正常恒牙列形成。根管充填材料的选择是影响乳牙根管治疗效果的重要因素之一。目前，可用于临床的乳牙根管充填材料种类繁多，本文就目前常用的乳牙根管充填材料性能及其临床应用情况作一综述。.
