Successful root canal treatment requires a thorough understanding of the normal root canal anatomy and possible variations for each tooth. Variations in the root canal anatomy are frequently associated with complex orientations of pulp tissues and complicating mechanical and chemical debridement. Inability to manage such complications may result in endodontic failure. Mandibular first premolars often exhibit a wide range of anatomic variations, complicating clinicians' treatment. This clinical case report discusses the cone-beam computed tomography (CBCT) diagnosis and nonsurgical management of a taurodontic mandibular first premolar with two roots and four canals under a dental operating microscope (DOM). In endodontically challenging cases, using a DOM and CBCT imaging can help the clinician gain a better understanding of the complex root canal anatomy, allowing the clinician to more efficiently explore, clean, shape, and obturate the root canal system.

This study aimed to evaluate the performance of a deep learning-based segmentation model for predicting outcomes of non-surgical endodontic treatment. Preoperative and 3-year postoperative periapical radiographic images of each tooth from routine root canal treatments performed by endodontists from 2015 to 2021 were obtained retrospectively from Thammasat University hospital. Preoperative radiographic images of 1200 teeth with 3-year follow-up results (440 healed, 400 healing, and 360 disease) were collected.

Background: Regenerative endodontics' primary objective is to establish a favorable environment in the root canal by removing infection, providing a sturdy scaffold, and sealing the apical end of the tooth tightly. These actions should promote pulp regeneration and root development.
Aim: This study evaluated histologically the regenerative potential of injectable hyaluronic acid (HA) hydrogel or collagen with blood clot as scaffolds during revascularization of immature necrotic dog's teeth.
