A survey was distributed to third- and fourth-year dental students (n = 467) assessing usage of institutional and external resources, perceived preparedness for clinical procedures, and frequency of fact-checking supplemental content. 94 students responded (20.1%). YouTube was the most commonly used non-curricular resource (77.7%), with significantly higher usage among third-year students (85.5%) compared to fourth-years (66.7%; p = 0.031). Only 41.5% of students reported fact-checking external content. A significant proportion of dental students rely on external resources to supplement their endodontic education.

Cone-beam computed tomography (CBCT) was used with the Ahmed classification system. A retrospective descriptive cross-sectional study analysed 388 maxillary premolars from CBCT scans of 97 participants obtained from participating private dental practices in Swakopmund and Windhoek and from the University of Namibia dental clinic. The root number and canal configuration were classified by the Ahmed system. Associations were assessed by comparing identical tooth types in the right and left maxilla. First premolars were mostly two-rooted (56.2%), and second premolars were mostly single-rooted (88.1%), with key configurations of 1MP1, 1MP1-2 and 2MP B1P1. Age-related changes showed increased 2MP B1P1 in first premolars and 1MP1-2-1 in second premolars. The dominant configurations in this Namibian sample align with other populations, emphasising the importance of population-specific data for endodontic treatment and supporting the relevance of the Ahmed classification.","PeriodicalId":55581,"journal":{"name":"Australian Endodontic Journal","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147846840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
