Persistent apical periodontitis even after nonsurgical retreatment demands for a surgical approach. This requires a thorough diagnosis and planning to eliminate the pathology and induce healing. This is sometimes challenging when the pathology is present in close relationship to the vital structures. In such cases, modern, sophisticated technology such as three-dimensional (3D) printing can come very handy in patient education as well as for planning and mock-up preparation of the surgery. In this case, a nonhealing persistent apical periodontitis in relation to 16 was surgically treated...

Invasive cervical resorption of the tooth is a relatively rare and uncommon phenomenon where the etiology remains idiopathic and unclear, and if not treated may lead to ultimate loss of tooth structure. Advancements in digital imaging have made the clinician to diagnose the pathological changes with great precision. Proper diagnosis and management of this condition is key to the successful outcome. The aim of this article was to elaborate two case reports of invasive cervical root resorption with surgical management using biocompatible restorative material...
