Present status and future directions: Root resorption.

Root resorption is the loss of dental hard tissue because of odontoclastic action. In permanent teeth, it is undesirable and pathological in nature. Root resorption may occur on the inner aspect of the root canal (internal root resorption) or on the outer aspect of the root (external root resorption). Regardless of its location, root resorption is irreversible, and may result in discomfort for the patient, requires management and/or, in some cases, results in the premature loss of the affected tooth. Root resorption is often challenging to accurately diagnose and manage. The aim of this narrative review is to present the relevant literature on the aetiology, pathogenesis, diagnosis and management, as well as discuss the future directions of diagnosis and management of root resorption.

The ins and outs of root resorption.

Root resorption is a poorly understood phenomenon and is often misdiagnosed and, as a result, inappropriately treated. The aim of this paper is to provide a practical guide for diagnosis of root resorption lesions using a simple classification, and to describe the principles of management of these resorptive defects in everyday practice.

External cervical resorption associated with the use of bisphosphonates: a case series.

Although the pathogenesis and etiology of external cervical resorption (ECR) are not well understood, several predisposing factors have been reported to potentially contribute toward the initiation of ECR. However, a potential link between systemic medication and ECR has not been reported. Bisphosphonates (BSPs) are 1 group of these medications (the amino-containing BSP), which are associated with an acute-phase response and the release of proinflammatory cytokines, which could be associated with the initiation of ECR. Therefore, a possible causal link between BSPs and ECR could be drawn.
