Conclusion
CBCT and clinical examinations including pulp vital testing and PPD are very important tools for periodontitis and/or endodontic lesions with a cemental tear located at labial/buccal and lingual/palatal sites. Complete removal of cemental fragments and periodontal regenerative treatment are indispensable clinical treatments for cemental tears with severe periodontal tissue destruction, although the size of the defect on root dentin after removal of cemental fragments and root planing in addition to the categories of class and stage (Lee et al., 2021) might be key factors that affect periodontal tissue regeneration.
