摘　　要：目的 两组镍钛锉根管预备系统对弯曲根管的成形力及术后疼痛发生率的临床对比研究,以期为临床治疗提供参考依据。方法 将安阳市第六人民医院牙体牙髓病2科2021年8月至2023年1月收治的106例成人牙髓病患者分为参照组(53例,53颗牙)、研究组(53例,53颗牙),分组方法为按照随机数字表法,参照组使用M3镍钛锉根管预备,研究组使用欧罗德卡镍钛锉根管预备,预备完成后根管内封氢氧化钙糊剂,复诊时常规根管充填。对比两组患者根管充填效果、成形能力、锉诊间疼痛、器械分离情况。结果 研究组的恰充率(96.23%)高于参照组(92.45%),但统计学比较无意义(χ^(2)=0.177,P>0.05);参照组与研究组在1-7 mm水平均发生不同程度的偏移,参照组(0.04±0.01)mm、(0.31±0.07)mm、(0.24±0.08)mm、(0.05±0.01)mm,偏移程度大于研究组(0.03±0.01)mm、(0.15±0.08)mm、(0.17±0.06)mm、(0.03±0.01)(t=5.148,10.958,5.096,10.296,P<0.05)参照组、研究组患者的锉诊间疼痛发生率为5.66%、1.89%,研究组相较于参照组降低,但经比较两组锉诊间疼痛统计学差异无意义(χ^(2)=0.260,P>0.05);研究组器械分离情况相较于参照组降低,但经比较两组器械分离情况统计学差异无意义(χ^(2)=0.000,P>0.05)。结论 成人牙髓病患者采用M3镍钛锉、欧罗德卡镍钛锉根管治疗均可提高恰充率,减轻患者疼痛,器械分离情况良好,相较于M3镍钛锉,欧罗德卡镍钛锉根管治疗成形能力好,推荐使用欧罗德卡镍钛锉进行根管预备。Objective To compare the clinical effect of the curved root canal to provide reference for clinical treatment.Methods 106 adult patients with dental pulp disease admitted to the department of cariology and endodontics(Ⅱ)at the Anyang Sixth People's Hospita from August 2021 to January 2023 were divided into a reference group(53 cases,53 teeth)and a study group(53 cases,53 teeth).The grouping method was based on a random number table.The reference group used M3 nickel titanium files for root canal preparation,while the study group used Orodka nickel titanium files for root canal preparation.After preparation,the root canal was sealed with calcium hydroxide paste,and regular root canal filling was performed during follow-up visits.Root canal filling effect,forming ability,pain in file room,and device separation were compared between the two groups.Results The filling rate of the study group(96.23%)was higher than the reference group(92.45%),However,the statistical comparisons were insignificant(χ^(2)=0.177,P>0.05);both the reference and study groups were shifted at 1-7 mm level,the reference group(0.04±0.01)mm,(0.31±0.07)mm,(0.24±0.08)mm,(0.05±0.01)mm.The degree of offset was greater than the study group(0.03±0.01)mm,(0.15±0.08)mm,(0.17±0.06)mm,(0.03±0.01)(t=5.148,10.958,5.096,10.296,P<0.05);the incidence of pain between patients in the reference group and study group was 5.66%and 1.89%,and the study group decreased compared with the reference group,but the statistical difference in pain between the two groups was insignificant(χ^(2)=0.260,P>0.05);the device separation in the study group decreased compared with the reference group,but the statistical difference between the two groups was insignificant(χ^(2)=0.000,P>0.05).Conclusion In adult patients,M3 NiTi file and Europa NiTi file can improve the filling rate and reduce the pain of patients.The device separation is good.Compared with M3 NiTi file,it is recommended to use Eurodka NiTi file for root canal preparation.
