Methods: A retrospective analysis was performed on 55 patients receiving antiresorptive therapy, categorized into a tooth-extraction group (n = 20) and an MRONJ group (n = 35). Standardized panoramic radiographs obtained at baseline (T0) and during the 6-month follow-up (T1) were evaluated for lamina dura thickness, trabecular bone alteration, osteosclerosis, cancellous bone loss, sequestration, and periosteal response. Statistical analyses were conducted on associations involving drug type, administration route, therapy duration, smoking, diabetes, hypertension, gender, and serum C-terminal telopeptide (CTX) levels. Results: The incidence of sequestrum development and cancellous bone loss was considerably higher in the MRONJ group. Sequestration demonstrated significant associations with both the duration of antiresorptive therapy (&gt;3 years) and intermediate-risk CTX levels. No significant correlations were found between CTX and other radiographic parameters. Lamina dura thickening, trabecular alterations, osteosclerosis, and periosteal reaction exhibited no differences across groups or in relation to smoking, diabetes, age, or gender; periosteal reaction was an uncommon and variable finding. Conclusions: Panoramic radiography provides clinically useful information in the evaluation of MRONJ, particularly for identifying sequestration and cancellous bone degradation. The formation of sequestrum appears to be the most indicative radiographic indicator, representing both the duration of treatment and biochemical risk.<\/jats:p>","DOI":"10.3390\/jcm15020698","type":"journal-article","created":{"date-parts":[[2026,1,15]],"date-time":"2026-01-15T11:13:21Z","timestamp":1768475601000},"page":"698","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Radiographic Patterns and Clinical Correlates of Medication-Related Osteonecrosis of the Jaw (MRONJ): A Retrospective Analysis"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0592-6235","authenticated-orcid":false,"given":"Mehmet Altay","family":"Sevimay","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Gazi University, 06490 Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8377-0155","authenticated-orcid":false,"given":"Sedat","family":"\u00c7etiner","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Gazi University, 06490 Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"102","DOI":"10.1016\/j.bjorl.2017.05.008","article-title":"Osteonecrosis of the jaws: A review and update in etiology and treatment","volume":"84","author":"Ribeiro","year":"2018","journal-title":"Braz.
