Objective: To investigate the influence of sociodemographic factors and characteristics attributed to the host, substrate and potential microorganisms in risk of early childhood caries on 2-to-5 years-old infants from a rural community of the Peruvian Amazon. Methods: Cross-sectional study in 155 pre-school children between 2-5 years old, from the district of Picha­naki. A clinical examination and questionnaire were carried out. For risk analysis, univariate and multivariate logistic regression models, corrected using the Holm-Bonferroni method and a bootstrapping with 10000 sam­pling cycles were used. Results: The prevalence of dental caries was 83.3%. Factors associated with dental caries were a history of urinary tract infections during pregnancy (p = 0.005), poor oral hygiene (p = 0.001), sharing utensils with their main caregiver (p = 0.018), and having older siblings with cavitie...
