Abstract

Abstract Introduction The coronal opening is essential, during endodontic treatment, for direct access to the root canals. Usually, in the anterior teeth, endodontic access is achieved on the palatal/lingual surface, more specifically in the cingulum region. However, the lack of observation for dental positioning can lead to some accidents and complications, such as buccal perforations, causing esthetic damage and compromising the treatment. Objective To evaluate the applicability of a new approach for performing coronal opening in anterior teeth, regarding the wear caused on the tooth crown, and to evaluate the ease of performing the new technique to minimize the risk of perforation. Material and method Ten students (n=10) from the Improvement in Endodontics program participated in the present study. Twenty artificial teeth were used, which were upper, central incisors. Each participant performed two coronal openings. First, with no guidance (Group A - Conventional Technique) and afterward, a new opening, but with guidance with the spherical diamond tip placed parallel to the long axis of the tooth (Group B - Modified Technique). Result The results showed that 90% of the participants considered the Modified Technique as having lower risk of accidents, as well as being easier for locating the pulp chamber. There was a statistical difference both in the measurement of the total area of wear and in the width, while there was no statistical difference in the height. Conclusion Preliminary data collected with the survey were satisfactory for the Modified Technique. Statistically, it showed a favorable difference in relation to the area of wear and the width. However, in height there was no statistical difference.
一种前牙根管通路的新方法-一项初步研究
在根管治疗过程中,冠状口是直接进入根管的必要通道。通常,在前牙中,根管通道是在腭/舌表面实现的,更具体地说是在带区。然而,缺乏对牙位的观察会导致一些意外和并发症,如口腔穿孔,造成美观损害和影响治疗。目的探讨一种新入路在前牙冠打开术中对牙冠磨损的适用性,并评价新入路的易操作性,以降低牙穿孔的风险。材料与方法来自牙髓学改善项目的10名学生(n=10)参与了本研究。使用了20颗人工牙,分别是上门牙和中门牙。每位参与者进行两次冠状动脉切开。首先,没有引导(A组-传统技术),然后,一个新的开口,但有引导,将球形钻石尖端平行于牙齿的长轴(B组-改进技术)。结果90%的参加者认为改良技术的意外风险较低,而且更容易定位牙髓室。在磨损总面积和宽度的测量上有统计学差异,而在高度上没有统计学差异。结论本调查所收集的初步资料对改良技术是满意的。从统计上看,它与磨损面积和宽度的关系有良好的差异。然而,在身高上没有统计学差异。
