Relative decrease in corporeal movements, escalating inactive lifestyles, and changes in dietary factors are strongly linked with the increasing incidence of overweight and obesity. Furthermore, obesity increases the risk of chronic disease and dental caries that significantly affects the quality of life of young children. The present study intends to explore the relationship between dental caries and obesity in children in Al-Kharj city, Kingdom of Saudi Arabia. Materials and methods The present descriptive study was designed as a cross-sectional study in which a total of 386 children in the age range of 6 to 12 years from elementary schools of Al-Kharj city and pediatric dental clinics in Prince Sattam Dental College were included. Results Mean decayed filled teeth (DFT) score was found to be considerably higher among obese children. Also, incidence of dental caries in deciduous dentition was found to be notably higher among obese children. Conclusion Obesity has a considerable outcome on prevalence of dental caries among primary schoolchildren in Al-Kharj city, Kingdom of Saudi Arabia. The importance of obesity is limited not only to systemic disorders but also in relation to carious lesions. Hence, educating primary schoolchildren about caries and its related factors is very important. Clinical significance High intake of free sugar is a wellestablished risk factor for dental caries and also for obesity.
