Abstract: Objective To explore the application effect of unique identification code in the full lifecycle management of dental handpieces. Methods Sixty newly purchased dental handpieces from August 2023 to August 2024 were selected as research objects. Among them, 30 dental handpieces were assigned to the control group and managed using traditional methods; the other 30 dental handpieces were assigned to the observation group and were coded before use with unique identification code. The differences in usage frequency, completeness of maintenance traceability, scrap rate, nursing staff management time, and healthcare provider satisfaction between the two groups were compared. Results The observation group showed higher usage frequency, higher mainenance treaceability completeness rate, lower scrap rate, lower management time of nursing staff, and higher satisfaction rate of medical staff than the control group （P<0.05）. Conclusion Unique identification code for the full lifecycle information traceability of dental handpieces can improve management quality, reduce labor costs, enhance healthcare provider satisfaction, and effectively ensure medical safety.
