| 摘 要： | 目的：比较冷牙胶侧加压充填技术与高温热塑充填技术根尖封闭效果。方法：选取离体颌牙40颗，随机分为A组（16颗牙）、B组（16颗牙）、实验阳性组（4颗牙）、实验阴性组（4颗牙），A组采用冷牙胶侧加压充填技术，B组采用高温热塑充填技术，比较分析不同组剐渗漏现象、顺应性、封闭性能。结果：高温热塑充填技术组渗入长度[（1．01±0．16）mm]明显少于冷牙胶侧方加压充填组；1．5、3．5mm横截面封闭能力、顺应性（0．9448±0．0221、0．9543±0．0200；0．9558±0．0164、0．9722±0．0142）、1．5、3．5mm横截面100～250封闭能力（0．9496±0．0168、0．95884-0．0176）、≥250封闭能力（0．9421±0．0165、0．9516±0．0214）明显高于冷牙胶侧方充填技术（P均〈0．05）。结论：高温热塑充填技术可以增强填充材料的顺应性，减少渗漏现象，提高封闲效果。

| Abstract: | Objective： To evaluate and compare apical sealing ability by cold lateral condensation of gutta-percha and high-tempetature thermoplasticized gutta-perch. Methods： A total of 40 jaw teeth were randomly divided into group A （16 teeh） ,group B （16 teeth）, the positive group （4 teeth）, the negative group （4 teeth）. Group A were given cold lateral condensation of gutta-percha, group B were given high tempetature thermoplasticized gutta-pereh. Leakage phenomenon, compliance, sealing ability between dif- ferent groups were compared. Result：Infiltration length of high-tempetature thermoplasticized gutta-perch groupE（1.01 0. 16） mm was significantly less than that of cold lateral condensation of gutta-percha group Under cross section in 1.5 mm or 3.5 mm sealing ability （0. 944 80. 022 1 vs. 0. 954 30. 020 0）, compliance （0.955 80.016 4 v.s. 0.972 20. 014 2）, sealing ability at 100250（0.949 6-0. 016 8 vsO. 958 8-＋0. 017 6）, 250 0. 942 1＋0. 016 5 v.. 0. 951 60. 021 4）were significantly higher than cold lateral condensation of gutta-percha（all P〈0.05）. Conclusions： High-tempetature thermoplasticized gutta-perch c bility. EK ability an enhance the compliance of fill material, reduce the leakage phenomenon, and improve sealing |
