Abstract
Introduction This case highlights the management of acute pulpitis in a fused mandibular molar using minimally invasive endodontic access, ultrasonic-activated chemomechanical preparation, and bioceramic material. Case description A 23-year-old female presented with a 6-month history of thermal sensitivity in tooth 37(lower left second molar), progressing to spontaneous and radiating nocturnal pain. Intraoral examination revealed a supernumerary cusp fused to the mesiobuccal surface of 37 with grayish discoloration at the fusion line. The tooth had positive percussion tenderness but no thermal sensitivity, mobility or periodontal pocketing. Cone-beam computed tomography (CBCT) revealed a fused supernumerary cusp with pulpal communication, a radiolucent area involving the pulp, apical radiolucency, and a distobuccally merged single root canal near the inferior alveolar nerve canal. A customized access cavity was made through the fused cusp to preserve marginal ridge and occlusal surface, followed by chemomechanical preparation using 3% sodium hypochlorite with ultrasonic activation. The canal system was obturated with iRoot SP (Innovative BioCeramix, Canada), activated ultrasonically to eliminate voids. Postoperative radiographs confirmed a compact filling, with minimal extrusion that did not affect the inferior alveolar nerve canal. Three days later, composite resin restoration was applied. Discussion Preoperative CBCT imaging, minimally invasive endodontic access and ultrasonic-activated chemomechanical preparationin were crucial in managing this case. iRoot SP demonstrated excellent adaptability to canal irregularities. Care must be taken to avoid overextension into critical anatomical structures. Conclusion/clinical significance The integration of CBCT diagnostics, ultrasonic disinfection, and bioactive sealers enhances precision endodontics.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
