Objective: To determine the prevalence and severity of dental fluorosis in the population aged 8-12 years old in public schools in Villavicencio, Colombia. Materials and Methods: A descriptive study, with voluntary participation and previous consent of the responsible adults, of 459 children aged 8 to 12 years, selected from a population of 32,306 students enrolled in public schools in Villavicencio, using probability sampling. This work is supported by the bioethics committee of the Universidad Cooperativa de Colombia. Clinical examination was carried out by six dentists previously calibrated by an expert in the diagnosis of dental fluorosis according Thylstrup and Fejerskov (TFI) obtaining Kappa indexes > 0.80. Exploratory data analysis (EDA), frequency distribution and inferential statistics (test partnership with Pearson Chi² a = 0.05) were performed with SPSS version 21.0. Licensed by Universidad Cooperativa de Colombia. Results: The prevalence of fluorosis (TFI ≥ 1) was 65.8% (n = 302) (95% CI = 61.5% to 68.5%). Boys presented a prevalence of 51.3% (n = 155) (95% CI = 47.3% to 55.3%) (p = 0.94). In urban areas the most affected district of origin was No. 6 with a prevalence of 70.8% (95% CI = 59.8% to 81.8%) (p = 0,84). The 31.4% of children had a TFI = 2, 23% one TFI = 1. The most affected teeth were premolars (48.2%) (40.6%), followed by lateral incisors (40.2%). Conclusion: In the population of 8-12 years old children of public Villavicencio schools a higher prevalence of fluorosis with a mild to moderate severity is present, representing a public health problem that requires intervention by the supervisory bodies.
