摘要/Abstract

摘要： 目的: 探讨不同根管冲洗液与根充糊剂对牙根抗折力的影响,为临床材料选择提供实验依据。方法: 选取170颗符合标准的下颌单根管前磨牙,随机分为5个实验组[A~E组分别使用生理盐水、1%NaClO、3%NaClO、5.25%NaClO及濡康诺牌口腔抗菌冲洗剂(Ultra Clean,UC)]和2个对照组(F组:不预备不充填;G组:预备不充填)。所有实验组根管预备采用M3 Pro 2016机用镍钛锉系统,并进一步按充填糊剂分为AH-Plus、C-root SP和Vitapex 3个亚组。根管预备后行标准冲洗与单尖法充填,样本经X线筛选、包埋模拟牙周膜后,通过万能试验机测定其抗折强度。结果: 根管机械预备显著降低牙根抗折力[G组:(254.30±26.74) N vs. F组:(673.16±29.06) N,P<0.05]。次氯酸钠类冲洗液显著削弱牙根抗折力,且呈浓度依赖性,其中5.25%NaClO组影响最为显著。在充填材料中,生物陶瓷类糊剂(C-root SP)所获得的牙根抗折强度高于树脂类(AH-Plus)与氢氧化钙类(Vitapex)。结论: 根管治疗中机械预备与化学冲洗均会降低牙根抗折强度,而生物陶瓷类根充糊剂有助于提升根管治疗后牙体的结构抗力性能。

Abstract: Objective: To evaluate the effects of different root canal irrigants and obturation sealers on the fracture resistance of tooth roots. Methods: A total of 170 mandibular single-rooted premolars meeting the criteria were selected and randomly divided into five experimental groups (Groups A-E, irrigated with normal saline, 1% NaClO, 3%NaClO, 5.25%NaClO, and Ultra Clean) and two control groups (Group F: no instrumentation or obturation; Group G: instrumentation only). All experimental groups were instrumented using the M3 Pro 2016 rotary nickel-titanium file system and further subdivided into three subgroups based on the obturation sealer used: AH-Plus, C-root SP, and Vitapex. After standardized irrigation and single-cone obturation, the samples were screened via X-ray, embedded to simulate the periodontal ligament, and subjected to fracture resistance testing using a universal testing machine. Results: Root canal instrumentation significantly reduced fracture resistance [Group G: (254.30±26.74) N vs. Group F: (673.16±29.06) N, P<0.05]. Sodium hypochlorite irrigants significantly weakened root fracture resistance in a concentration-dependent manner, with the 5.25% NaClO group showing the most pronounced effect. Among the obturation materials, the bioceramic sealer (C-root SP) resulted in higher fracture resistance compared to resin-based (AH-Plus) and calcium hydroxide-based (Vitapex) sealers. Conclusion: Both mechanical instrumentation and chemical irrigation reduce root fracture resistance, while the use of bioceramic sealers can enhance the structural integrity of teeth after root canal treatment. Clinical material selection should comprehensively consider material properties to optimize treatment outcomes.
