Abstract: Successful root canal treatment requires management of the bacterial infection within the root canal space and protection of residual tooth structure with direct/indirect restorations. Long-term success depends upon prevention of re-infection of the root canal space as well as ensuring favourable distribution of the occlusal forces throughout the residual tooth structure. Appropriate planning and design of the final restoration prior to initiating root canal treatment is paramount in achieving this objective. This article describes simultaneous restorability assessment and access cavity preparation to optimize outcome of both endodontic and prosthodontic treatment of the endodontically involved tooth.

Clinical relevance: This paper proposes a method to improve visibility and reduce iatrogenic errors whilst simultaneously facilitating effective design of the definitive restoration based on the quantity and distribution of residual tooth structure.
