The research was conducted with the objective of defining the concentration of lead in deciduous dental enamel according to gender, age, and severity. Thirty-five microbiopsies were performed on the dental enamel of 35 children from the Quichas community; the sampling was non-probabilistic and convenient. 100% of the children had lead levels in their dental enamel. The results show lead concentrations ranging from 5.65 to 12.83 μg/g in children between 4 and 6 years of age. A significant relationship was demonstrated between lead concentration and age. It was concluded that the median concentrations are higher as age increases. Regarding the severity of lead concentration, it was found that 94.3% of the children had moderate concentrations (5 μg/g-10 μg/g) and 5.7% had severe concentrations (10 μg/g or higher). However, no statistically significant differences were found according to gender. It is recommended to further study the concentration of lead in dental enamel, analyze lead levels in blood and saliva, conduct studies on permanent teeth, and compare lead concentrations in deciduous and permanent teeth.
