This study aimed to perform an analysis of obtaining apical patency indexes during endodontic treatments considering gender, age, pulpoperiradicular diagnosis and canal/tooth (n. 639/383). Following previous clinical procedures, a thin K-File (No. 20, 15, 10 or 08) was used to achieve apical patency. These specific data and some demographic and clinical information were submitted to the statistical analysis (p < 0.05). Significant statistical differences were not identified considering gender (p = 0.156) and age (p = 0.793). However, in 14.6% of the canals of vital teeth and 14.1% of the canals of necrotic teeth without periapical lesions, apical patency could not be achieved, which occurred in only 7% of the canals of necrotic teeth with periradicular disease (p = 0.009). Considering canal/tooth, apical patency was more challenging to obtain in canals of posterior teeth (p = 0.000). The pulpoperiapical diagnosis and canal/tooth significantly influenced the obtaining of apical patency.
本研究旨在分析在牙髓治疗中获得根尖通畅指数，考虑性别、年龄、牙髓-根尖诊断和根管/牙（n=639/383）。按照先前的临床程序，使用细 K 锉（20、15、10 或 08 号）来实现根尖通畅。这些具体数据以及一些人口统计学和临床信息被提交给统计分析（p<0.05）。考虑到性别（p=0.156）和年龄（p=0.793），没有发现显著的统计学差异。然而，在 14.6%的活髓牙根管和 14.1%的无根尖病变的坏死牙根管中，无法达到根尖通畅，而在有根尖病变的坏死牙根管中仅发生 7%（p=0.009）。考虑到根管/牙，后牙根管获得根尖通畅更加困难（p=0.000）。牙髓-根尖诊断和根管/牙显著影响根尖通畅的获得。
