Abstract

Abstract Objective A retreatment is a conservative approach than periapical surgery in case of failed root canal treatment. Retreatment techniques that are efficient and faster should be the main concern to treat endodontic failure. This study aimed to compare the time required by various hand and rotary retreatment systems for the retrieval of gutta-percha (GP) from root canals. Materials and Methods A total of 120 extracted single-rooted premolar teeth with straight canals were chosen. Biomechanical preparation was completed using the Step-Back approach keeping the master apical file size 35. Then, teeth were down-packed and back-filled with System B device, along with AH Plus sealer. The teeth were categorized into six groups ( n = 20) at random as per techniques applied for retrieval of GP: group I hand instrumentation (Hedstrom files and Gates-Glidden drills); group II ProTaper Universal Retreatment (PTUR) system; group III Mtwo Retreatment (Mtwo R) system; group IV D-RaCe; group V R-Endo; and group VI Mani Gutta Percha Remover (NRT-GPR). A chronometer was used to measure the time required for retrieval of GP. Data were examined by comparative evaluation of one-way analysis of variance and chi-square test. Results Among all the retreatment techniques used, D-RaCe was faster in GP retrieval than other groups. NRT-GPR system also took less time than other groups except for the D-RaCe system. The Mtwo R system was the slowest among all groups. Conclusion D-RaCe retreatment instruments required extensively less time for retrieval of GP than other groups ( p < 0.001).

六种不同复治技术对鲈鱼回治所需时间的比较：一项体外研究

【摘要】目的在根管治疗失败的情况下，再治疗比根尖周手术更保守。有效和快速的再治疗技术应该是治疗牙髓衰竭的主要关注点。本研究旨在比较不同的手持式和旋转式再处理系统从根管中取出杜仲胶(GP)所需的时间。材料与方法选择拔除的直管单根前磨牙120颗。采用Step-Back方法完成生物力学准备，保持主根尖文件大小为35。然后，用系统B设备和AH Plus封口机对牙齿进行下填充和回填。根据拔牙方法随机分为6组(n = 20): 1组手工器械(Hedstrom锉和Gates-Glidden钻);II组ProTaper通用再处理(PTUR)系统;Mtwo Retreatment (Mtwo R)系统;IV组D-RaCe;V组R-Endo;第六组马尼古塔芭尔茶去除剂(NRT-GPR)。用计时器测量提取GP所需的时间。资料采用单因素方差分析和卡方检验比较评价。结果在所有的再处理技术中，D-RaCe的GP检索速度比其他组快。除D-RaCe系统外，NRT-GPR系统所需的时间也比其他组短。m2r系统是所有组中最慢的。结论D-RaCe再治疗器械的GP检索时间明显少于其他组(p < 0.001)。

期刊介绍： European Journal of General Dentistry (EJGD) is one of the leading open-access international dental journal within the field of Dentistry. The aim of EJGD is publishing novel and high-quality research papers, as well as to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. EJGD publishes articles on all disciplines of dentistry including the cariology, orthodontics, oral surgery, preventive dentistry, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research.Moreover, EJGD also publish the scientific researches evaluating the use of new biomaterials, new drugs and new methods for treatment of patients with different kinds of oral and maxillofacial diseases or defects, the diagnosis of oral and maxillofacial diseases with new methods, etc. Moreover, researches on the quality of life, psychological interventions, improving disease treatment outcomes, the prevention, diagnosis and management of cancer therapeutic complications, rehabilitation, palliative and end of life care, and support teamwork for cancer care and oral health care for old patients are also welcome. EJGD publishes research articles, case reports, reviews and comparison studies evaluating materials and methods in the all fields of related to dentistry.
