Clinical and scanning electron microscopic features of invasive cervical resorption in a maxillary molar

External cervical resorption (ECR) is the loss of dental hard tissue as a result of odontoclastic action. It is a dynamic process that involves periodontal, dental and in later stages pulpal tissues. Over the last two decades, ECR has attracted increased interest; this is in part due to novel micro-CT and histopathological techniques for its assessment and also improved radiographic detection using CBCT. This literature review will cover the aetiology, potential predisposing factors, histopathology and diagnosis of ECR. Part 2 will cover the management of ECR.

“…4). Perforation of the root canal is prevented by a thin protective layer of inner dentin and predentin (2,52). The predentin has been shown to contain an anti-invasion factor and resorption inhibitor that prevent ECR from advancing into the root canal until the ECR is very advanced (53).…”

“…The predentin has been shown to contain an anti-invasion factor and resorption inhibitor that prevent ECR from advancing into the root canal until the ECR is very advanced (53). It has also been suggested that the outer surface of enamel might also be resistant to resorption as a result of preferential odontoclastic dissolution of interprismatic enamel (52).…”

“…It often appears as an irregular, asymmetrical radiolucency through which the root canal outline is traceable. Deposition of calcific tissue can result in a more radiopaque mottled appearance, and this may represent a reparative stage in the development of the lesion (Iqbal , Mavridou et al . 2016a).…”
