Following previous clinical procedures, a thin K\u2010File (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 (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.05). Significant statistical differences were not identified considering gender (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.156) and age (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.793). 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 (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.009). Considering canal\/tooth, apical patency was more challenging to obtain in canals of posterior teeth (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.000). The pulpoperiapical diagnosis and canal\/tooth significantly influenced the obtaining of apical patency.<\/jats:p>","DOI":"10.1111\/aej.12737","type":"journal-article","created":{"date-parts":[[2023,2,3]],"date-time":"2023-02-03T16:53:29Z","timestamp":1675443209000},"page":"323-329","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Analysis of obtaining apical patency indexes during endodontic treatments considering gender, age, pulpoperiradicular diagnosis and canal\/tooth\u2014A clinical study"],"prefix":"10.1111","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1901-7270","authenticated-orcid":false,"given":"Ricardo","family":"Machado","sequence":"first","affiliation":[{"name":"Department of Endodontics School of Dentistry, Pontifical Catholic University of Paran\u00e1 \u2010 PUC\/PR  Curitiba Paran\u00e1 Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudemir","family":"de Souza\u00a0J\u00fanior","sequence":"additional","affiliation":[{"name":"Private Clinical Practice  Foz do Igua\u00e7\u00fa Paran\u00e1 Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaqueline","family":"Nascimento","sequence":"additional","affiliation":[{"name":"Department of Endodontics School of Dentistry, Pontifical Catholic University of Paran\u00e1 \u2010 PUC\/PR  Curitiba Paran\u00e1 Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eduardo Donato Eing","family":"Elgelke\u00a0Back","sequence":"additional","affiliation":[{"name":"Private Clinical Practice  Joinville Santa Catarina Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Comparin","sequence":"additional","affiliation":[{"name":"Department of Endodontics School of Dentistry, Paranaense University \u2010 UNIPAR  Francisco Beltr\u00e3o Paran\u00e1 Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00e9rgio Aparecido","family":"Ign\u00e1cio","sequence":"additional","affiliation":[{"name":"Department of Biostatistics School of Dentistry, Pontifical Catholic University of Paran\u00e1 \u2010 PUC\/PR  Curitiba Paran\u00e1 Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ulisses Xavier da","family":"Silva\u00a0Neto","sequence":"additional","affiliation":[{"name":"Department of Endodontics School of Dentistry, Pontifical Catholic University of Paran\u00e1 \u2010 PUC\/PR  Curitiba Paran\u00e1 Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,2,3]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(55)90303-0"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joen.2014.05.013"},{"key":"e_1_2_7_4_1","first-page":"126","article-title":"Iatrogenic errors during root canal instrumentation performed by dental students","volume":"13","author":"Hendi SS","year":"2018","journal-title":"Iran Endod J"},{"key":"e_1_2_7_5_1","first-page":"30","article-title":"Radiographic evaluation of root canal treatment performed by undergraduate students, part I;
