Abstract: ABSTRACT: Preservation of pulpal vitality is a fundamental objective of modern minimally invasive dentistry; however, the absence of an objective and real-time method for measuring remaining dentin thickness during cavity preparation frequently results in accidental pulp exposure and irreversible pulpal injury. The present invention discloses a novel electrical dental probe designed for precise, real-time assessment of remaining dentin thickness during operative dental procedures. The device comprises a miniaturized electrode integrated within a dental probe tip, an electronic signal processing unit configured to measure and analyze variations of dental tissues, and an output interface configured to provide visual and/or audio feedback corresponding to dentin thickness and proximity to the pulp. The invention operates on the principle that dentin and pulpal tissues exhibit distinct electrical properties, thereby enabling accurate estimation of dentin thickness. The probe provides immediate clinical guidance to the operator, enhances procedural safety, prevents accidental pulp exposure, and promotes conservative tooth preparation. The proposed invention represents a significant advancement in dental diagnostic instrumentation by introducing an objective, reliable, and clinically applicable solution for dentin thickness monitoring, thereby improving treatment outcomes, preserving tooth vitality, and advancing the standard of care in restorative dentistry.ural effici
