Patient and Staff Safety Incidents in Korean Dental Practice: Implications for Quality of Care and Safer Healthcare Delivery

Objectives: Patient safety is central to healthcare quality, yet dental practice also involves occupational risks for professionals. This study examined the lifetime prevalence and types of patient- and staff-safety incidents among Korean dental professionals and explored associated demographic, professional, and institutional factors. Methods: A cross-sectional survey was conducted among 439 dental professionals in South Korea. Participants reported lifetime experience of predefined safety incidents, institutional safety factors, and demographic and occupational characteristics. Descriptive statistics, profession-based comparisons, and multivariable logistic regression were applied. Results: Overall, 89.1% of respondents reported at least one safety incident. The most common patient-safety events were aspiration or ingestion of teeth or prosthetic materials and instrument-related injury, whereas sharps injuries and verbal abuse were the leading staff-safety issues. Dentists and dental hygienists differed significantly in response knowledge, liability insurance coverage, and safety education. The presence of institutional safety protocols was associated with higher reported incident experience, which may reflect greater recognition and reporting rather than a causal increase in harm. Conclusions: Safety incidents are highly prevalent in Korean dental practice and represent an underrecognized quality-of-care and workforce-safety issue. Integrated strategies including occupational-hygiene measures, structured safety education, non-punitive reporting, and stronger organizational preparedness are needed to improve dental healthcare delivery.
