Oral and Maxillofacial Surgery:  The root of the cause: a clinical case report of the surgical removal of a retained root via an extra-oral approach

Feedback:  0 comments, 0 ratings


Abstract: Retained roots are commonly seen as an incidental finding in general practice following radiographic examination, many being asymptomatic. However, over time they may migrate, develop pathological change and become symptomatic for the patient. This article illustrates root migration using an interesting clinical case to demonstrate how it can present, and the surgical techniques required in its removal. In this particular case, the retained root of a lower right second molar migrated to below the right side of the inferior alveolar nerve.

Clinical relevance: It is important to recognize when referral for a specialist opinion is appropriate.
