Patients (<jats:italic>N<\/jats:italic>\u00a0=\u00a0106) with pulpitis or pulp necrosis, with or without apical periodontitis, were included. During the first appointment, glide path was performed with ProGlider and shaping with ProTaper Next. Working length was detected four times. Working length was then re\u2010recorded prior to filling during the second appointment and a 0.5\u2009mm threshold was selected as the minimum clinically meaningful variation. A logistic regression model was used to evaluate the impact of tooth anatomy, preoperative pulp status, apical periodontitis and lesions of endodontic origin on working length variation. Working length varied between first and second appointments in 34% of patients. The presence of apical periodontitis was the only variable significantly associated with variation in working length (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.011). These data suggest that working length should be re\u2010checked prior to root canal filling to prevent procedural errors.<\/jats:p>","DOI":"10.1111\/aej.12703","type":"journal-article","created":{"date-parts":[[2022,10,25]],"date-time":"2022-10-25T10:19:07Z","timestamp":1666693147000},"page":"107-112","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Working
