The restorative treatment of non-vital teeth is a common problem for dentists. In pediatric dentistry, partially erupted molars with extensive coronal destruction or less coronal height have an insufficient crown height to gain retention for the full crown cast restoration, hence endocrown appears to be a suitable option for restoring the endodontically treated teeth in these situations. Although the traditional crown supported by radicular metal posts is still extensively used in dentistry, it has been heavily criticized for its invasiveness. There are currently new materials and treatment possibilities based solely on adhesion. Over the last few decades, advancements in adhesive dentistry have made significant contributions to cosmetic and restorative dentistry. The endocrown is advised for the repair of severely damaged molars, which necessitates the use of particular restoration techniques to meet biomechanical criteria. The endocrown is recommended when the pulp chamber provides suitable conditions for retention. The endocrown preserves tooth structure while being minimally invasive. Clinical investigations have demonstrated that the endocrown has a long functional life, and it has emerged as a potential option for the cosmetic and functional restoration of endodontically treated molar teeth. The current lecture will discuss endocrown for from A-Z.
