Children infected with COVID-19 have a critical part in community-based viral transmission. This study aimed to evaluate knowledge, awareness, attitudes, and behaviors of parents of pediatric dental patients on COVID-19 and to present required actions to prevent its spreading. A total of 524 parents took part in this cross-sectional study. A self-administered questionnaire was prepared for determining sociodemographic characteristics and socioeconomic status of parents, along with their COVID-19-related knowledge, awareness, attitudes, and behaviors. In total, 90.6% of parents were unaware that disease may show no symptoms; 61.1% and 32.6% did not know roles of "close contact with asymptomatic patients" and "dentistry practices" in transmission, respectively; 30.2% thought it could be transmitted to their children at dental clinics, and only 16.4% stated their children as carriers. Parents need to be informed on COVID-19 transmission through contact with asymptomatic individuals, risks associated with dentistry practices, and role of children in transmission.
