“…The presence of extensive periradicular lesions, an incompletely formed apex, apical foramen diameter, the diameter of the file used for measurement, the presence of exudate, anatomical variations such as the presence of lateral foramen, and apical foramen blockage can compromise the effectiveness of EALs (4,9,22,23). However, these parameters were not evaluated in the present study, as it was a laboratory study.…”

“…Thus, from a biological point of view, chemical–mechanical preparation must be performed along the entire length of the root canal. In this context, the precise determination of the true length of the root canal is extremely important during endodontic treatment (1,4,5). Accurate working length may avoid unwanted complications such as step formation, iatrogenic damage to the periapical tissues, and postoperative symptoms.…”

“…Accurate working length may avoid unwanted complications such as step formation, iatrogenic damage to the periapical tissues, and postoperative symptoms. Furthermore, inaccurate measurement can lead to incomplete and inadequate instrumentation and filling of the root canal, and consequently the persistence of infection that is associated with failure of endodontic treatment (2,4,6).…”

“…The effectiveness and accuracy of EALs have been assessed through different in vitro and in vivo studies, and have demonstrated accuracy of 75%–97% (1–4,13–18). The differences in these studies are mainly related to the methods, the types of EALs and the sample evaluated.…”

This study aimed to determine the accuracy of four electronic apex locators (EALs) (I‐Root, Propex Pixi, Novapex and Bassi iRoot Apex), using artificial mandibular and maxillary permanent molars. The root length (RL) from 40 artificial teeth was initially determined with Kerr hand files. Then, the electronic RL were obtained for the same root canals with each EAL, and the results were compared with those obtained using hand files. The accuracy of the EALs was determined through analysis of the divergences observed in relation to the lengths obtained with files. All EALs were effective for determining the RL in the artificial teeth, showing results similar to those obtained by hand. The Bassi iRoot Apex had higher accuracy (96.7%) than the Propex Pixi (89.1%) and Novapex (85.8%) (P < 0.05). Based on the results, all EALs tested had a similar performance, and artificial teeth may be used to determine the accuracy of these devices.

Determining the apical limit of root canal preparation has proved to be a matter of continuous debate. During root canal instrumentation, soft tissue or debris get impacted in the apical region causing canal blockage. This can be avoided if apical patency is maintained. A major concern over apical patency is extrusion causing periapical tissue irritation and delaying or hindering periapical healing. The aim of this review was to evaluate the literature regarding the influence of apical patency on success of root canal treatment. A search of the literature was conducted via PubMed using the terms "apical patency" OR "patency file". Inclusion criteria were: articles published in English, between the years 2000 and 2020, and were neither case reports nor reviews. A total of 32 articles were selected. Clinical studies directly investigating the influence of apical patency on root canal treatment outcome are limited. In-vitro and in-vivo studies were found evaluating amount of extrusion, canal cleanliness, and shaping associated with apical patency examined this influence indirectly. According to the available literature, there is little evidence to contraindicate the use of apical patency or suggest it has a negative effect on root canal treatment outcome. However, more evidence of high quality is required to confirm this.
