DAMASCENO, Leonardo Silveira et al. Cemental tear: a case report with nonsurgical periodontal therapy. Rev. odonto ciênc. [online]. 2012, vol.27, n.1, pp.74-77. ISSN 1980-6523. http://dx.doi.org/10.1590/S1980-65232012000100014.
PURPOSE: To report a case of cemental tear, a rare periodontal condition characterized by total or partial separation of the dental cementum, mainly addressing issues related to its diagnosis and treatment. CASE DESCRIPTION: A 50 years-old man sought dental assistance complaining of pain located in the mandibular left second premolar that showed a 4 mm probing depth with the presence of a foreign body in the distal gingival sulcus. Radiographic examination demonstrated a slight radiopaque fragment detached from the root. The fragment was removed without a periodontal flap. Histopathological examination was performed and evidenced the presence of a cementum fragment with cementum lamellae, cementocytes, and adhered periodontal ligament fibers, confirming the diagnosis of cemental tear. CONCLUSION: After a follow-up of 2 years, the nonsurgical periodontal therapy showed satisfactory clinical and radiographic outcome. Therefore, this approach should be a suitable and predictable treatment modality for the cemental tear.
