Oral Health Status of Korean Students and Associated Fasting Plasma Glucose in Overweight/Obese Individuals

This study aimed to evaluate the current oral health status of Korean children and adolescents and investigate the correlation between fasting plasma glucose levels and oral health in individuals with overweight and obesity. A total of 121,682 participants were selected from the Survey of School Health Examination data provided by the Ministry of Education over the last 5 years to assess recent oral health status and related factors. Among them, 18,105 students with overweight or obesity who had their fasting plasma glucose levels measured were assessed for blood glucose-related analysis. Based on fasting blood glucose levels, the participants were categorized into normal, impaired fasting glucose, and diabetes groups. The associations of these groups with dental caries, oral hygiene, and periodontal diseases were investigated. There were significant associations between demographic factors, health-related behaviors, and blood glucose levels with oral health. Increased fasting blood glucose levels were associated with poor oral health. These results suggest that glycemic management is important in enhancing the oral health of overweight and obese children and adolescents.
