Dental resorption is a physiological or pathological process that may be initiated and propagated by various mechanisms, including mechanical, surgical, thermal or chemical injury. It refers to non-bacterial destruction of dental tissue resulting from clastic cell activity. It is predominantly asymptomatic in the permanent dentition and may be misdiagnosed and/or poorly understood. This article describes the different types of dental resorption, the features of each and a guide on how to manage them. Some interesting cases are also highlighted.
CPD/Clinical Relevance: It is important to understand, identify and diagnose different types of resorption.
Article
Dental resorption refers to non-bacterial destruction of dental tissue resulting from osteoclastic cell activity.1 It is predominantly asymptomatic in the permanent dentition and may be misdiagnosed and/or poorly understood. Dental resorption can occur both internally and externally and is known to be initiated and propagated by many factors. Pulpal necrosis, trauma, periodontal treatment, orthodontic treatment and tooth whitening agents are the most commonly described causative agents.2 Root resorption in the permanent dentition is caused by osteoclast-like cells called odontoclasts. Cementum and predentine usually protect the root surface and typically do not undergo resorption as they contain potent inhibitors of resorption.3 However after an initial stimulus, the dentine can be exposed and odontoclasts can bind and initiate the resorptive process.3 Resorption will continue while the stimulus is present.
