摘　　要：本研究通过根尖渗漏试验和可见光分光光度法比较热侧压充填法和传统侧压充填法的根尖封闭能力。结果表明：加用封闭剂热侧压充填法的根尖封闭能力最佳，优于单纯热侧压充填法（Ｐ＜０．０５）及传统侧压充填法（Ｐ＜０．０１）。但由于国产牙胶尖易粘至热充填器上带出，操作不便，目前推广应用热侧压法尚有困难。An apical leakage test and a visible light spectrophotmetric analysis were performed to compare the apical sealability of warm lateral condensation and conventional lateral condensation technipues.The results showed that warm lateral with sealer delivered best sealability. It was superior to warm lateral without sealer (P< 0. 05)and conventional lateral condensation technique (P<0. 01) Because of its unconvenient operation causing by native-made putta-percha,it is difficult to use warm lateral condensation technique widely in our country.
