Waveone系统结合一次法在乳前牙根尖周炎中的临床应用
[摘要]目的 分析Waveone结合一次根管治疗法在乳前牙慢性根尖周炎治疗中的应用效果。方法 选取2016年9月～2017年8月在我院门诊就诊的50例乳前牙慢性根尖周炎患者作为研究对象。采用电脑单纯随机抽样法将患者为观察组、对照组，每组25例。观察组采用Waveone系统，对照组给予传统不锈钢k锉进行根管预备。两组都采用一次法进行根管治疗和充填，比较两组的根管预备时间及术后疗效。结果 观察组和对照组的预备时间分别为（5.13±0.15）、（7.26±0.19）s，两组比较，差异有统计学意义（P<0.05）。观察组术后的有效率为 96%，明显高于对照组的72%，差异有统计学意义（P<0.05）。结论 Waveone结合一次根管治疗法治疗乳前牙慢性根尖周炎的效果顯著，还可有效缩短操作时间，值得临床推广。

[Abstract]Objective To analyze the application effect of waveone system combined with one-off root canal therapy in chronic periapical periodontitis of the anterior deciduous teeth.Methods From September 2016 to August 2017，50 patients with chronic periapical periodontitis of the anterior deciduous teeth treated in our outpatient clinic were selected as research objects.They were divided into the observation group （n=50） and control group （n=50） by computer random sampling method.In the observation group，Waveone system was used.In the control group，traditional stainless steel k file was used for root canal preparation.The two groups were both treated with one-off root canal therapy and filling.The time of root canal preparation and postoperative effect between the two groups were compared.Results The preparation time in the observation group and control group was （5.13±0.15） s and （7.26±0.19） s respectively with a statistical difference （P<0.05）.In the observation group，the total postoperative effectiveness rate was 96%，and 72% in the control group，which was displayed a statistical difference （P<0.05）.Conclusion For the treatment of chronic periapical periodontitis of anterior deciduous teeth，application of Waveone combined with one-off root canal therapy can obtain a remarkable effect，and effectively shorten the operation time，which is worthy of clinical promotion.

儿童乳牙的牙龈较薄弱、牙槽骨较疏松、髓腔较大、解剖结构较简单，因此牙髓和根尖周组织容易受到细菌侵害，形成根尖周炎[1]。乳牙慢性根尖周炎的发病率很高，急性期和慢性期的症状持续得不到有效的治疗，则会破坏牙体牙列的完整性和咀嚼功能的发挥，进而影响继承恒牙胚的正常发育及萌出[2]。治疗乳牙根尖周炎的关键之处是彻底清除根管内及根尖周围的感染物质，根管治疗术是治疗根尖周炎的首选方法。传统的根管治疗方式需要患儿多次就诊，增加患儿的就诊次数和操作配合时间，继而增加了患儿的痛苦。随着根管预备器械和根充材料的不断发展和改进，一次法根管治疗术的治疗效果得到越来越多口腔医生和研究者的认可[3-4]。儿童口腔医生在临床中追求更好的材料、更简便的方式、更舒服快速的临床效果来解除患儿根尖周炎的临床症状。
