Background: Patient safety climate constitutes an important element for quality improvement. Its current evidence base has been generated in hospital settings in developed countries. Studies in dentistry are limited., Objective: To systematically explore the evidence regarding assessing patient safety climate in dentistry., Methods: We developed a search strategy to explore MEDLINE, SCOPUS, and Web of Science databases from January 1st, 2002, to December 31st, 2022, to include observational studies on patient safety culture or patient safety climate assessment. Methodological features and item data concerning the dimensions employed for assessment were extracted and thematically analyzed. Reported scores were also collected., Results: Nine articles out of 5584 were included in this study. Most studies were generated from high-income economies. Our analysis revealed methodological variations. Non-randomized samples were employed (ranging from 139 to 656 participants), and response rates varied from 28% to 93.7%. Three types of measurement instruments have been adapted to assess patient safety climate. These mainly consisted of replacing words or rewording sentences. Only one study employed an instrument previously validated through psychometric methods. In general, patient safety climate levels were either low or neutral. Only one study reported scores equal to or greater than 75., Discussion: Despite diverse assessment tools, our two-decade analysis reveals a lag compared with medicine, resulting in methodological variations for assessing patient safety climate. Collaboration is vital to elevate standards, prioritize patient safety across oral healthcare services, and advocate for integrating safety climate into local and national quality and patient safety strategies., (© 2024 American Association of Public Health Dentistry.)
