Supporting data for "Impact of kindergarten dental outreach service in primary school students"

The Faculty of Dentistry, University of Hong Kong, has been providing kindergarten outreach dental services (KDOS), comprising oral examination, oral health education, and silver diamine fluoride application. This retrospective observational study was conducted to evaluate the association between KDOS and various oral health-related outcomes, including dental caries experience, treatment received, and oral health-related quality of life (OHRQoL) in primary school students. Grade 3 or 4 primary school students participating in the School Dental Care Service (SDCS) were recruited from four school dental clinics in 2022. A cross-sectional questionnaire survey was administered to children and their parents to collect self-reported data. Children's clinical examination and treatment records were provided by the Hong Kong SAR government Department of Health. Children’s OHRQoL was assessed using two Child Perceptions Questionnaire (CPQ) short forms.
