摘　　要：目的观察手用镍钛根管器械ProTaper在后牙根管治疗中的效果。方法220例后牙根管治疗病例随机分为PT组(镍钛根管锉组)110例,392个根管,采用ProTaper手用镍钛锉冠根向深入法预备根管;KH组110例,397个根管,采用ISO标准型不锈钢K型锉和H型锉,冠根向深入法预备根管。比较2组根管预备时间、预备后疼痛发生率、根管充填恰填率。结果PT组在根管预备时间、根管预备后疼痛发生率上均低于KH组(P<0.05),根管充填恰填率高于KH组(P<0.05),差异有显著性。结论手用ProTaper能够保持根管初形、省时省力、安全,明显提高根充效果,值得推广。Objective To observe the effects of hand ProTaper NITI instrument in the root canal treatment. Methods 220 cases who needed root canal treatment were randomly divided into two groups. The root canals were prepared with hand ProTaper（ PT group： 110 cases, 392 root canals, gradually forward method） and ISO standard stainless steel type K and H files（ KH group： 110 patients, 397 root canals, gradually forward method） , respectively. The preparing time, pain after preparation and root canal obturation effection were evaluated. Results In root canal preparation time and incidence of pain, root canal obturation rate were significantly lower in PT gronp than in KH group （ P 〈 0.05 ）. The difference was statistically significant. Conclusions The hand ProTaper instrument can maintain root canal form, save time, obviously improve the root obturation effection safely. It is worth popularizing.
