[摘要]目的:探讨Protaper镍钛器械根管预备不可复性牙髓炎后残髓与IAE的关系。方法:按Crown-down预备技术进行根管预备,约诊时记录初次预备后是否疼痛和发生时间、程度并做再次清理预备,仔细观察是否存在残髓和预备过程疼痛与否,必要时行多次清理和预备。结果:第1次预备后疼痛者往往在第2次预备时发现残髓。结论:残髓的存在是导致根管治疗期间疼痛应足够重视的原因之一,约诊期间最好行二次或以上次数的根管清理和预备。

Abstract: ObjectiveTo investigate their relationship between the residual pulp and the IAE on root canal preparation of irreversible pulpitis by Protaper nickel-titanium instruments. MethodsRoot canal preparation was made by crown-down technique .The time and extent of pain were recorded after the first root canal preparation.And then,a clear preparation was again made,to carefully observe whether there is residual pulp and pain in preparation process. If necessary,many times of cleaning and preparation were used. ResultsResidual pulp were often found at the second preparation,when the pain was found after the first preparation. ConclusionResidual pulp was lead to one of the pain reasons during root canal therapy.It should be sufficient attention.Two times and more times root canal cleaning and preparation should used during appointment.

根管治疗术是治疗牙髓病和根尖周病最有效的方法已经得到人们的公认,随着现代根管治疗学的发展,许多新的理念和器械广泛应用于实践,极大的提高了根管治疗的成功率,但根管治疗期间急症(endodonticinterappointmentemergency, IAE)一直困扰临床,是目前较为棘手的问题之一。根管治疗期间急症是指根管治疗期间的急性炎性反应,主要表现为剧烈的疼痛和肿胀,给患者造成很大痛苦并增加就诊次数,同时也给医患之间的沟通和信任带来障碍。有报道根管治疗期间疼痛大部分(65%)出现在根管治疗初诊后的第1天[1],如何预防和减少IAE的发生,学者们从不同的角度进行了研究,文献屡有报道。笔者自2005年以来以Protaper镍钛器械按Crow-down技术进行根管治疗术,通过长期的临床实践和观察,发现根管残髓的存在可能是IAE发生应引起足够重视的原因之一,彻底清理残髓对减少IAE的发生及对根管治疗成功率起着至关重要的作用,现报道如下。
1临床资料
1.1 一般资料:2005年10月～2009年11月,共收集在我科经笔者治疗的2 326颗不可复性牙髓炎病例(含外伤冠折露髓患者,活髓牙因修复需要选择性拔髓患者),符合后述样本采纳标准的有1 883颗,年龄10～81岁,男1 016例(1 085颗),女702例(798颗),其中前牙827颗,前磨牙454,磨牙602例。
1.2不可复性牙髓炎诊断标准[2]:急性牙髓炎,包括慢性牙髓炎急性发作;慢性牙髓炎,包括残髓炎;逆行性牙髓炎。
1.3样本纳入和排除标准:纳入标准:不可复性牙髓炎的病例(含外伤冠折露髓患者,活髓牙因修复需要选择性拔髓患者)经根管预备后,同一参考标志下初次测定根长和再次预备后重测根长肉眼误差在0.5mm以内,且无管壁侧穿,并经X线试尖片验证牙胶距根尖距离在0 ......
