Abstract:Objective: To determine the prevalence of dental anxiety (DA) in children between 6-10 years of age treated at public health services (PHS) in Valdivia, Chile.Materials and Methods: An observational cross-sectional study was designed. The prevalence of DA before dental treatment was measured using the Facial Image Scale (FIS) in children between 6-10 years of age treated at public health services (PHS) of Valdivia, Chile, from March to June 2015.Results: Of the 200 children surveyed, 22.5% had dental anxiety; 51% were girls (n=102); average age 7.9 ± 1.45. Conclusion:The prevalence of DA in Valdivia is higher than that observed in a similar study conducted in Santiago, Chile. We suggest the implementation of FIS in pediatric dental care, to ensure better adaptation and adherence to the dental treatment.
