PubMed\/MEDLINE, Scopus, Web of Science and Embase were searched up to November 2025 without year restrictions; studies in any language were eligible, provided that an English abstract was available for screening. Cross\u2010sectional radiographic studies reporting the prevalence of hypercementosis in humans using periapical radiographs, panoramic radiographs or cone\u2010beam computed tomography (CBCT) were included. Pooled prevalence estimates were calculated at the patient and tooth levels using a DerSimonian\u2013Laird random\u2010effects model with logit transformation. Risk of bias was assessed using an adapted Newcastle\u2013Ottawa Scale, and the certainty of evidence was appraised using the GRADE approach.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Ten observational studies (14\u2009881 participants) were included. At the patient level, the pooled prevalence of hypercementosis was 3.9% (95% CI: 2.0%\u20137.3%), with very high heterogeneity (I\n                      <jats:sup>2<\/jats:sup>\n                      \u2009=\u200998%). Tooth\u2010level meta\u2010analysis, based on three studies evaluating 52\u2009666 teeth, showed a pooled prevalence of 0.25% (95% CI: 0.06%\u20131%), also with substantial heterogeneity (I\n                      <jats:sup>2<\/jats:sup>\n                      \u2009=\u200998%).

However, extreme heterogeneity and very low certainty of evidence limit the precision of prevalence estimates. Standardized diagnostic criteria and harmonized imaging protocols are needed to improve reproducibility. Within contemporary CBCT\u2010based prognostic frameworks, hypercementosis may be considered a potential modifier of anatomical complexity, warranting further outcome\u2010oriented investigation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/iej.70147","type":"journal-article","created":{"date-parts":[[2026,3,23]],"date-time":"2026-03-23T10:46:08Z","timestamp":1774262768000},"page":"1537-1556","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Prevalence of Hypercementosis in Radiographic Studies: A Systematic Review and Meta\u2010Analysis With Clinical Implications for Endodontic Assessment"],"prefix":"10.1111","volume":"59","author":[{"given":"Carlos","family":"Segura\u2010Raya","sequence":"first","affiliation":[{"name":"Department of Pre\u2010Clinical Dentistry, Faculty of Biomedical and Health Sciences Universidad Europea de Madrid  Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6141-0546","authenticated-orcid":false,"given":"V\u00edctor","family":"Diaz\u2010Flores","sequence":"additional","affiliation":[{"name":"Department of Pre\u2010Clinical Dentistry, Faculty of Biomedical and Health Sciences Universidad Europea de Madrid  Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Milagros","family":"Mart\u00edn\u2010Jim\u00e9nez","sequence":"additional","affiliation":[{"name":"Department of Stomatology (Endodontic Section), School of Dentistry University of Sevilla  Sevilla Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0427-9059","authenticated-orcid":false,"given":"Juan J.","family":"Segura\u2010Egea","sequence":"additional","affiliation":[{"name":"Department of Stomatology (Endodontic Section), School of Dentistry University of Sevilla  Sevilla Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,3,23]]},"reference":[{"key":"e_1_2_9_2_1","article-title":"Saving a Mandibular Molar With Distal Root Resorption: A Case Report","volume":"17","author":"AlHelal A.
