The phenomenon is believed to be elicited by overloading or acute trauma from occlusion. In this case report a patient, with a history of periodontal health, presented with an acute periodontal lesion on the distal aspect of a bridge abutment tooth. Periapical radiographs demonstrated an extensive vertical intrabony defect adjacent to the vital abutment tooth containing a radiopaque \u201cforeign body.\u201d Histological examination of the surgically removed \u201cforeign body\u201d revealed a piece of dental cementum with some attached soft tissue. The lesion responded well to a surgical approach. Healing was uneventful and periodontal health was restored. This case illustrates that cemental tear should be considered as a differential diagnostic entity in isolated sites with rapid periodontal breakdown. <jats:italic>J Periodontol 1992;63:220\u2013224<\/jats:italic>.<\/jats:p>","DOI":"10.1902\/jop.1992.63.3.220","type":"journal-article","created":{"date-parts":[[2012,3,21]],"date-time":"2012-03-21T03:00:49Z","timestamp":1332298849000},"page":"220-224","source":"Crossref","is-referenced-by-count":39,"title":["Cementai Tear Related to Rapid Periodontal Breakdown: A Case Report"],"prefix":"10.1002","volume":"63","author":[{"given":"J.
