Clinically, there were no complaints, no percussion pain or sinus tract. Radiologically, the tooth had an obliterated canal with an apical radiolucency. The tooth was diagnosed with asymptomatic apical periodontitis. Microguided Endodontic treatment was performed with the help of a 3D\u2010printed guide. The root canal was localized initially with the aid of the 3D\u2010printed guide using a round carbide bur with a head diameter of 0.8\u00a0mm. Then, the canal was shaped and cleaned using mechanical rotary files under copious irrigation with 5% NaOCl, 17% EDTA and passive ultrasonic activation. A completely healed apical area of tooth 22 was visible after 6\u00a0months on periapical radiographs and small field of view CBCT.<\/jats:p><\/jats:sec><jats:sec><jats:title>Key learning points<\/jats:title><jats:p>\n<jats:list list-type=\"bullet\">\n\n<jats:list-item><jats:p>Using the Microguided Endodontics concept, a minimally invasive access was achieved up to the middle of the root, in a maxillary lateral incisor with pulp canal obliteration (PCO) and apical periodontitis.<\/jats:p><\/jats:list-item>\n\n<jats:list-item><jats:p>This technique is a valuable tool for the negotiation of PCO, reducing chair time and risk of iatrogenic damage to the root.<\/jats:p><\/jats:list-item>\n<\/jats:list>\n<\/jats:p><\/jats:sec>","DOI":"10.1111\/iej.13031","type":"journal-article","created":{"date-parts":[[2018,10,20]],"date-time":"2018-10-20T05:14:18Z","timestamp":1540012458000},"page":"540-549","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":83,"title":["Microguided Endodontics: a case report of a maxillary lateral incisor with pulp canal obliteration and apical periodontitis"],"prefix":"10.1111","volume":"52","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8233-3025","authenticated-orcid":false,"given":"A.","family":"Torres","sequence":"first","affiliation":[{"name":"Department of Oral Health Sciences University Hospitals Leuven, Endodontology KU Leuven Leuven Belgium"},{"name":"OMFS IMPATH Research Group Department of Imaging and Pathology Faculty of Medicine KU Leuven Leuven Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Shaheen","sequence":"additional","affiliation":[{"name":"OMFS IMPATH Research Group Department of Imaging and Pathology Faculty of Medicine KU Leuven Leuven Belgium"},{"name":"Department of Oral and Maxillofacial Surgery University Hospitals Leuven Leuven Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Lambrechts","sequence":"additional","affiliation":[{"name":"Department of Oral Health Sciences University Hospitals Leuven, Endodontology KU Leuven Leuven Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Politis","sequence":"additional","affiliation":[{"name":"OMFS IMPATH Research Group Department of Imaging and Pathology Faculty of Medicine KU Leuven Leuven Belgium"},{"name":"Department of Oral and Maxillofacial Surgery University Hospitals Leuven Leuven Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Jacobs","sequence":"additional","affiliation":[{"name":"OMFS IMPATH Research Group Department of Imaging and Pathology Faculty of Medicine KU Leuven Leuven Belgium"},{"name":"Department of Oral and Maxillofacial Surgery University Hospitals Leuven Leuven Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,11,8]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.joen.2017.12.009"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1741-2358.2004.00039.x"},{"key":"e_1_2_7_4_1","unstructured":"American Association of Endodontists(2005)Endodontic Case Difficulty Assessment and Referral.https:\/\/www.aae.org\/specialty\/wp-content\/uploads\/sites\/2\/2017\/07\/ss05ecfe.pdf.
