Clinical examination revealed a defective composite restoration with ICDAS 3, 2 root caries on tooth #17. Radiographs confirmed pulp involvement associated with an extensive defect on the distal surface of the root. The diagnosis was asymptomatic irreversible pulpitis with normal apical tissues. After local anesthesia and complete caries removal, a pre-endodontic build-up was performed using a sectional matrix system (Palodent® V3, Dentsply Sirona, USA) to reconstruct coronal walls and minimize contamination risk during root canal therapy. Biomechanical preparation was done with reciprocating NiTi instruments (Reciproc Blue®, VDW, Germany) followed by single-cone obturation with a bioceramic sealer. The final restoration was digitally designed using an intraoral scanner and CAD software. An indirect lithium disilicate adhesive onlay was selected to restore occlusal function. At follow-up, the tooth showed no symptomp and functionally stable. <strong>Conclusion</strong>: The integration of pre-endodontic build-up with indirect adhesive restoration offers a conservative and effective approach for managing posterior teeth with extensive root defects, preserving structural integrity and ensuring long-term clinical success.</p> <p>&nbsp;</p> Steven Tanjung Opik Taofik Hidayat Copyright (c) 2026 SONDE (Sound of Dentistry) 2026-05-22 2026-05-22 11 1 1 12 http://114.7.153.31/index.php/sod/article/view/13568 <p><strong>Introduction:</strong> The middle mesial canal (MMC) is an anatomical variation occasionally encountered in mandibular first molars and often overlooked during endodontic treatment, potentially compromising clinical outcomes. This case report underscores the importance of recognizing and managing an MMC in five-canals mandibular molar. <strong>Methods: </strong>A 16-year-old male presented with lingering pain in the lower right posterior region. Clinical and radiographic findings led to a diagnosis of symptomatic irreversible pulpitis with symptomatic apical periodontitis in tooth #46. Canal exploration employed SLOB radiographic technique, magnification, ultrasonic troughing, and application of Krasner and Rankow’s laws. Five canal orifices were located—three in the mesial root, including a middle mesial canal, and two in the distal root. Canal preparation was achieved using Reciproc Blue instruments, coupled with passive ultrasonic irrigation for enhanced debridement. Obturation was performed with gutta-percha and a bioceramic sealer, chosen for its superior flowability and bioactivity. A full-coverage indirect overlay was placed to reinforce the remaining tooth structure. <strong>Results:</strong> At one-month follow-up, the patient reported complete resolution of symptoms, with radiographs showing well-obturated canals, intact periapical structures, and a functional restoration. <strong>Discussion:</strong> The presence of an MMC demands meticulous assessment and advanced visualization techniques. Knowledge of pulpal anatomy, effective instrumentation, and appropriate restorative choices are essential for long-term success. <strong>Conclusion</strong>: Successful endodontic outcomes depend on comprehensive canal identification, effective disinfection and obturation, and appropriate post-endodontic restoration.</p> Marita Anggaraini Irmaleny Irmaleny Copyright (c) 2026 SONDE (Sound of Dentistry) 2026-05-22 2026-05-22 11 1 13 34
