Cone-beam computed tomography (CBCT) images proved to be a reference diagnostic aid for detecting the etiological relationship between chronic apical periodontitis and maxillary sinusitis. There were retrospectively evaluated a total of 109 CBCT images (47 males and 62 females) from a pool of CBCT scans taken for routine diagnosis and treatment planning in consecutive 353 patients. The CBCT images were acquired with Veraviewepocs 3D P (R100) equipment (J. Morita MFG Corp., Kyoto, Japan). The scan parameters were 90 kV, 5 mA, 9.4 s exposure time, 125 \u03bcm spatial resolution and 40\u00d740 mm field of view (FoV). The aim of this CBCT study was to find out the influence of space separating apical lesions and sinus floor on subsequent EAS. There were observed four categories of anatomical rapports, such as tangent contact, protruding contact, 1\u20132 mm separating interval, and over 2 mm separating interval. The highest incidence was recorded in molars for tangent contact (47.69%) and in premolars when the apical lesions were situated at 1\u20132 mm distance from sinus floor (7.69%). The abnormalities revealed on CBCT scans of maxillary sinus have been mucosal hyperplasia, dome-shaped opacification, periostitis, and sinus opacification with air-bubbles. A four class classification related to the anatomical distance between the chronic apical lesions and sinus floor was suggested.<\/jats:p>","DOI":"10.47162\/rjme.65.3.13","type":"journal-article","created":{"date-parts":[[2024,11,28]],"date-time":"2024-11-28T11:43:48Z","timestamp":1732794228000},"page":"507-515","source":"Crossref","is-referenced-by-count":2,"title":["Odontogenic maxillary sinus disease: a cone-beam computed tomography surveillance"],"prefix":"10.47162","volume":"65","author":[{"name":"Department of Endodontics, Faculty of Dental Medicine, Carol Davila University of Medicine and Pharmacy, Bucharest, Romania","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paula","family":"Perlea","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristina Coralia","family":"Nistor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Endodontics, Faculty of Dental Medicine, Carol Davila University of Medicine and Pharmacy, Bucharest, Romania","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristina Teodora","family":"Preoteasa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Scientific Research Methodology, Faculty of Dental Medicine, Carol Davila University of Medicine and Pharmacy, Bucharest, Romania","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Irina Maria","family":"Gheorghiu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Odontotherapy, Faculty of Dental Medicine, Carol Davila University of Medicine and Pharmacy, Bucharest, Romania","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oana Alexandra","family":"Mladin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Family Medicine, Faculty of Medicine, Carol Davila University of Medicine and Pharmacy, Bucharest, Romania","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandru Andrei","family":"Iliescu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Oral Rehabilitation, Faculty of Dental Medicine, University of Medicine and Pharmacy of Craiova, Romania","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"26736","published-online":{"date-parts":[[2024,11,8]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"\"[1] Radman WP.
