Abstract	Introduction: Conservative endodontics aims to preserve dental tissues as much as possible while ensuring adequate access to the root canal system. Conservative access cavities (CACs) represent an approach designed to minimize dentin removal during endodontic treatment. Methods: This experimental study was conducted on 30 mandibular molars. CACs were prepared using a protocol combining CBCT imaging, optical magnification, and ultrasonic tips to ensure accurate planning and controlled preparation. Residual dentin preservation and procedural complications were evaluated. Results: Volumetric analysis demonstrated good preservation of dental tissues, with slight over-preparation observed in only 5 cases. No instrument fracture was reported during the study. Discussion: The results confirm the potential of CACs to reduce tissue loss while maintaining adequate endodontic access. CBCT plays an essential role in three-dimensional anatomical analysis and preoperative planning, whereas optical magnification and ultrasonic tips improve operative precision. This approach may contribute to optimizing clinical outcomes in minimally invasive endodontics.
