Permanent teeth with an indication for endodontic treatment can be treated via the truss access cavity design rather than traditional access cavity protocol using copious irrigation. The teeth were then given post-endodontic restorations. Endodontically treated teeth did not show any post-operative symptoms or any presence of post-operative periapical radiolucency or flare-up. The main objective of Orifice oriented access/truss access approach mainly stresses on the preservation of the healthy tooth structure with the minimally invasive approach. This minimal invasive approach in truss access designs avoids the need for conventionally placed crowns. Thus, the aim of this case report was to strategically plan truss access cavity designs on premolars. 8 25 2020 52 56 10.31254/dentistry.2020.5205 http://www.dentistryscience.com/IJDR_202052_05.pdf
