An experimental model for cervical resorption in monkeys

Abstract

Abstract The aim of the present study was to develop an experimental model for cervical root resorption and to study the significance of the junctional epithelium for the prevention of cervical resorption. Marginal experimental cavities covered by a thin plastic foil presented a dentin surface devoid of epithelial coverage. The dentin surface displayed numerous resorption cavities containing a cell‐rich granulation tissue with a moderate chronic inflammation. Cavities to which no plastic foil had not been added, however, were all covered by a thin squamous epithelium. At no level did any of the originally denuded dentin surfaces come in contact with mucosal or periodontal connective tissue. The present study indicated that an incomplete epithelial coverage of a marginal dentin surface in combination with marginal gingivitis or periodontitis is sufficient to maintain a progressive cervical resorption.
