Efficient Management of Necrotic Mandibular Molar Using Single-Visit Endodontics and Endocrown: A Case Report

Introduction: Single visit endodontic treatment has become a practical and efficient approach, especially for patients seeking faster and more convenient dental care. This method reduces chair time, minimizes the risk of inter-appointment contamination, and improves overall patient satisfaction. In cases involving lower molars with extensive coronal damage, immediate restoration is essential to prevent reinfection and restore function. Endocrowns offer a conservative restorative option by utilizing the pulp chamber for retention, eliminating the need for post placement, reducing the risk of root fracture, providing a durable, esthetic, and time-efficient solution for structurally compromised posterior teeth. 

Description of Case: A 21-year-old female presented with a symptomatic, cariously exposed mandibular first molar, which caused throbbing pain, especially at night. This tooth was diagnosed with pulpal necrosis and normal apical tissues. Endodontic therapy was performed in a single visit then restored with a lithium disilicate endocrown one week later, following adhesive bonding protocols and proper surface conditioning. The final restoration was evaluated clinically and radiographically. 

Discussion: Recent evidence supports single-visit endodontics as a safe and effective option when proper disinfection protocols and case selection are followed. Endocrowns preserve remaining tooth structure while achieving high fracture resistance, especially when bonded using dual-cure resin cement. The combination of both techniques minimizes clinical time and maximizes long-term success. 

Conclusion: This case illustrates that combining single-visit endodontic treatment with lithium disilicate endocrown restoration provides a conservative, efficient, and durable treatment strategy for nonvital posterior teeth.
