Pathological root resorptions of dental hard tissues is a perplexing phenomenon which is often resembled as a “puzzle” to be solved by dentists in their daily clinical practice. Resorptions can appear with different clinical and radiographical characteristics and they can occur either at the inner aspect of the root canal (Ιnternal Resorptions) or the outer aspect of the root (External Resorptions). Regardless of their location, root resorptions are irreversible and may result in discomfort and symptoms for the patient, requiring management in some cases, whilst if left untreated they may result in premature loss of the affected tooth. To ensure prevention or early detection and optimal treatment of root resorptions it is essential to understand the underlying pathophysiological processes and to know when it is indicated to intervene and how to approach and treat them. The aim of this presentation is to update clinicians with the most recent literature with regards to etiology of different types of root resorptions and provide a practical clinical guide and tips for optimal diagnosis and endodontic management, ultimately aiding in solving the “puzzle” of root resorptions.
