Cervical Cemental Tears in Older Patients With Adult Periodontitis. Case Reports

Abstract

This communication reports 5 cases of cervical and 1 apical cemental tears. The diagnosis of the cervical tears was made by a characteristic feature which presented radiographically as a prickle-like body. The fragment of cementum could be detached by root planing or during periodontal surgery and uneventful healing was obtained following these procedures. The process of aging in addition to continuous occlusal strain may lead to this phenomenon. Cervical cemental tear may be one of the contributing factors in the progress of adult periodontitis.

Cemental tear on a mandibular second molar: a case report

“…Only one case occurring in the mandibular left fi rst molar has been heretofore reported. 5 This report describes clinical aspects, diagnosis, and treatment of cemental tears in the mandibular second molar. Clinically, a number of diagnostic procedures such as patient history, clinical symptoms, periodontal examination, pulp test, radiographic examination, and exploratory surgery should be used.…”

“…Clinically, a number of diagnostic procedures such as patient history, clinical symptoms, periodontal examination, pulp test, radiographic examination, and exploratory surgery should be used. [1][2][3][4][5] However, early diagnosis of cemental tears is often diffi cult because the clinical signs precede the radiographic changes. Only when the fractured fragment detaches from the root surface does it become discernible on a radiograph, as with the second molar of this case.…”

“…4 Only one previous report demonstrated a cemental tear on the mandibular fi rst molar. 5 To date, no cemental tear on the second molar has been reported. [1][2][3][4][5][6][7][8][9] Separations of cementum at an early stage cannot be detected solely by radiographs.…”

“…Cemental tears are usually accompanied by marked periodontal or periapical destruction. [1][2][3][4][5] Previous studies have found that they affect mainly single-rooted teeth, particularly the incisors and premolars. 4 Only one previous report demonstrated a cemental tear on the mandibular fi rst molar.…”

Histological assessment of root cementum at periodontally healthy and diseased human teeth.

“…The cementum, which is continuously deposited and rarely remodeled, is an important component of periodontium and also contains various proteins which facilitate cell migration, attachment, differentiation and proliferation (1)(2)(3). Progression of plaque-induced chronic inflammatory periodontal disease leads to continuous loss of periodontal attachment and exposure of the root cementum to the oral environment.…”
