A total of 400 mandibular molars (200 first and 200 second molars) were analyzed. Only teeth with fully developed roots and no prior endodontic treatment were included. Morphological features were assessed in axial, sagittal, and coronal CBCT views. The number of roots, number of canals per root, and canal configurations were recorded based on Vertucci\u2019s classification. The presence of radixentomolaris and radix paramolaris was also noted. Statistical analysis was performed using the Chi-square test (p \u2264 0.05).Results: Mandibular first molars exhibited predominantly two-rooted anatomy (98%), with 2% presenting a third distolingual root (radix entomolaris). Second molars displayed more variation, with 5% showing a single root, 4% with three roots, and 1% with four roots. Canal configuration analysis revealed that the mesial root of first molars most commonly exhibited Vertucci Type IV (83.7%), while distal roots showed a predominance of TypeI (60.2%). In second molars, mesial roots also frequently presented Type IV (51.1%), whereas distal roots overwhelmingly exhibited Type I (94.4%). Three- and four-rooted molars were more commonly found in second molars. ....( abstract truncated at 250 words)<\/jats:p>","DOI":"10.62438\/tunismed.v104i02.6316","type":"journal-article","created":{"date-parts":[[2026,5,6]],"date-time":"2026-05-06T21:27:09Z","timestamp":1778102829000},"source":"Crossref","is-referenced-by-count":0,"title":["Cone-Beam Computed Tomography Assessment of Mandibular Molar Root and Canal Morphology in a North African Population"],"prefix":"10.62438","volume":"104","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5080-4179","authenticated-orcid":false,"given":"Aymen","family":"Ben Hadj Khalifa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ghada","family":"Ayari","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Malek","family":"Abidi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hana","family":"Moalla","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rim","family":"Kallala","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Soumaya","family":"Touzi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chiraz","family":"Baccouche","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"31112","published-online":{"date-parts":[[2026,4,1]]},"container-title":["La Tunisie M\u00e9dicale"],"original-title":[],"deposited":{"date-parts":[[2026,5,6]],"date-time":"2026-05-06T21:27:10Z","timestamp":1778102830000},"score":1,"resource":{"primary":{"URL":"https:\/\/latunisiemedicale.com\/index.php\/tunismed\/article\/view\/6316"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,4,1]]},"references-count":0,"journal-issue":{"issue":"02","published-online":{"date-parts":[[2026,4,1]]}},"URL":"https:\/\/doi.org\/10.62438\/tunismed.v104i02.6316","relation":{},"ISSN":["2724-7031","0041-4131"],"issn-type":[{"value":"2724-7031","type":"electronic"},{"value":"0041-4131","type":"print"}],"subject":[],"published":{"date-parts":[[2026,4,1]]}}}
