Factors associated with uncooperative behavior by Brazilian preschool children in the dental office.

The purpose of this study was to assess the uncooperative behavior of low income preschool children receiving dental treatment and the factors associated with that behavior. The sample consisted of 177 Brazilian children of both sexes, ages from three to six years. The children were observed during their dental appointments and their behavior was categorized by the Frankl Behavioral Rating Scale. The oral health of the children was evaluated on the basis of a clinical examination and classified using the dmft index. A history taking with the child's parent or guardian provided current medical condition, dental history, and family situation. Of the children, 1 percent presented definitely positive behavior, 59 percent positive behavior, 28 percent negative behavior, and 12 percent definitely negative. A significant association was found between children with negative behavior and the variables of the child's age, parent's or guardian's education, learning or behavioral problems, parent's or guardian's anxiety, child oral health status, general health problems, history of hospitalization, and dental history.
