Abstract
BACKGROUND/PURPOSE: Dental caries is one of the most common oral diseases in children worldwide, especially in Taiwan. This study investigated dental professionally topical fluoride application (PTFA) and children's dental use for dental caries under the National Health Insurance (NHI) system in Taiwan from 2008 to 2021. MATERIALS AND METHODS: The population data and medical records of the NHI system were obtained from the websites of the Ministry of the Interior and the Ministry of Health and Welfare, respectively. The dental PTFA services and dental use indicators for dental caries were analyzed from 2008 to 2021. RESULTS: The number of out-patient visits for dental PTFA services increased from 221,675 in 2008 to 1,078,099 in 2021. The total increase of the out-patient visits was 856,424 with a total increase rate of 386.34%. The one-year increase was 65,879 with a one-year increase rate of 29.72%. Among the 3 age groups of children, their dental use indicators almost presented decreasing trends from 2008 to 2021. Moreover, in general, the dental use indicators showed a negative correlation with the number of the overall out-patient visits for dental PTFA services from 2008 to 2021. CONCLUSION: In Taiwan, there is a negative correlation between the dental use indicators in NHI system and the number of the overall out-patient visits for dental PTFA services from 2008 to 2021. However, the problem of dental caries in children is still serious and there is still a space for improvement in the oral health education for child caregivers and children.
