Abstract
Objective: To verify if an early tooth extraction can harm children's quality of life from 6 to 8 years old, affected by early and severe caries in childhood. Methods: Three schools participated in the survey, with children aged six to eight years. A questionnaire was designed to assess routines and the child's health history. Researchers also prepared an individual clinical record, and the ceo-d and CPO-D indexes were used to evaluate caries' experience in primary and permanent teeth, respectively. The study was approved by the Research Ethics Committee. Results: A total of 141 volunteers were evaluated. The highest prevalence of dental caries was 76.56% of volunteers from the public school, then 72.73% in those from the private school (Qui², p = 0.744). There is difficulty in speaking or social interaction in 15.62% and 7.79% of children from public and private schools, respectively. Conclusion: There was a presence of caries of early establishment in the children of the study, and such presence can interfere in the volunteers' quality of life.
