Abstract

This article describes the process of establishing the ‘National Child Oral Health Improvement Programmes for Chile database’ via request, collation and linkage of national, regional and municipality level aggregated data (2008–19) of: child oral health programmes, interventions and activities; corresponding child dental caries outcomes; water fluoridation coverage; and area-based socioeconomic deprivation levels, to conduct a comprehensive evaluation of oral health complex interventions. The cohort consists of aggregated electronic dental health care routine data from all the 346 Chilean Municipalities from the year 2008 to 2019, including dental examinations of 4 117 537 children aged 0 to 6 years and primary care and child oral health programmes, activities and interventions linked to non-health data including population, community water fluoridation levels and coverage, and area-based deprivation indexes. Researchers who require access to the database linked to routine health information in conjunction with non-health information from the municipalities can download it from the ‘Enlighten: Research Data’ repository of the University of Glasgow: doi: 10.5525/gla.researchdata.1331.
