An association was also observed between lesion height and periodontal condition (<i>p</i> = 0.043). In conclusion, ECR performed a significant correlation with ABL in the studied population (<i>p</i>  < 0.05). Three-dimensional characterization of ECR lesions and their relationship with bone loss patterns and periodontal status underscores the critical role of imaging in the early detection of potentially progressive lesions.</p>","PeriodicalId":13947,"journal":{"name":"International Journal of Dentistry","volume":"2026 ","pages":"5186337"},"PeriodicalIF":2.2,"publicationDate":"2026-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13570412/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148955825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
