O-11 Invasive Cervical Resorption Outcomes

CE Hours: 1.5

Description: The objective of ECR treatment is to remove the lesion, firmly seal the cavity, while maintaining a strong functional tooth. Up to date, treatment of ECR was based solely on the extent of resorption (class). However, new research has indicated that ECR is far more complex as multiple factors can affect its progression. Thus, our treatment approach should be updated. In this presentation we propose a step-wise treatment approach strategy on how to treat ECR cases. The criteria for choosing the most appropriate treatment were based not only on the ECR class but on additional factors such as: the existence of bone-ingrowth, patient symptoms, size, number and position of the portal(s) of entry, oral hygiene level, occlusion, existence of parafunctional habits and the probing feasibility. Based on these criteria, different treatment options were selected such as: 1) monitoring 2) extraction or 3) treatment by internal, external or a combination approach. To asses this proposed approach we evaluated the 10 year outcome of the overall and individual treatment options.

Learning Objectives:  

• Describe the complexity of ECR and how it affects the treatment decision.
• Design ECR treatment strategy.
• Define how each treatment affects the outcome.
