Aust Dent J 2021 Apr 17. Epub 2021 Apr 17.

Division of Endodontics, School of Dentistry, University of Minnesota, Minneapolis, MN, USA.

Cemental tear is defined as cementum fragment completely or partially detached from the root surface, and it has been associated with localized rapid periodontal breakdown. Although history of trauma and/or attrition may be risk factors, the etiopathology of cemental tear remains unknown. This case series aims to discuss the clinical, radiographic and histopathologic features of cemental tears to aid clinicians in making differential diagnosis. Read More

Cemental tear: An unusual cause for persisting endodontic periodontal lesion.

Indian J Dent Res 2019 Jan-Feb;30(1):140-143

Centre for Dental Education and Research, Division of Conservative Dentistry and Endodontics, All India Institute of Medical Sciences, New Delhi, India.

Cemental tear represents a rare form of root surface fracture which makes teeth prone to periodontal breakdown. The diagnosis of cemental tear becomes a challenge as it is usually neglected or misdiagnosed and is also underreported in the literature. Correct diagnosis and early treatment of cemental tear can prevent further periodontal breakdown and may preserve the affected tooth for a longer duration. Read More

Watanabe Dental Clinic, 1870-6 Kusabuka Numakuma Town, Fukuyama City, Hiroshima Prefecture, Japan.

A cemental tear is a pathologic condition in which a complete or incomplete separation of the cementum occurs along the root surface and is usually accompanied by a deep periodontal pocket. Past articles report that the incidence of cemental tears has usually been limited to 1 tooth per individual. We encountered a clinical case with cemental tears involving 14 teeth in 1 individual.

Severe localized periodontal destruction associated with cervical cemental separation.

Gen Dent 2005 May-Jun;53(3):212-4

US Army Dental Corps, Ft. Bragg, USA.

Cemental separations and tears are secondary etiological factors that may lead to rapid periodontal destruction if the lesion communicates with the oral cavity and allows bacterial invasion. Although many cemental tears that occur on proximal surfaces can be diagnosed radiographically, separations on the facial or lingual surface that cannot be detected on radiographs may present a diagnostic dilemma. This article describes a case of lingual cemental separation on a maxillary incisor, with subsequent successful surgical correction utilizing an osseous graft. Read More

Atypical localized deep pocket due to a cemental tear: case report.

J Contemp Dent Pract 2003 Aug 15;4(3):52-64. Epub 2003 Aug 15.

Dental Hygiene Department at the Oregon Health & Sciences University School of Dentistry in Portland, Oregon, USA.

A 71-year old patient with a history of minimal periodontal attachment loss presented with an asymptomatic, non-bleeding, isolated deep pocket on the mesio-facial of a central incisor. Such localized, deep pockets are most frequently associated with a root fracture or an abscess, but in this case an atypical ledge-like projection determined to be a cemental tear was detected at the base of the 6 mm pocket. Periodontal flap surgery revealed a partial detachment of the cementum. Read More
