OBJECTIVETo investigate the relationship between the uncooperative behaviors of first-visit-dental children and correlative factors that include children's temperament, severe of dental caries and so on in order to help dentists to make personal dentistry therapy plan for each child to prevent and deal with children's uncooperative behaviors.

METHODSFrom the pediatric dentistry clinic, 195 first-visit-dental children (aged 3-7 years) from Dec. 2007 to Dec. 2008 were randomly selected to accept dental examination and accepted corresponding treatment according to personal therapy plans. Children's clinic behavior was valued during treatment. The parents were asked to complete NYLS temperament parents scale questionnaires for 3-7 years old children.

RESULTSAmong the 195 children, there were 114(58.46%) had dental fear and anxiety(DFA) and 66 (33.85%) had dental behavior management problem (DBMP). As the children's age increased, the incidence of DBMP decreased. There were no statistical relationship between genders and children's DFA/DBMP. The children's severity of dental caries was related to their dental behavior, the more serious the caries, the more incident the DFA/DBMP of children. There were no statistically significant differences for the DFA/DBMP of temperament type children. But the score of sensory threshold was higher in DFA children, while physiological rhythmicity was lower in DBMP, the differences were significant.

CONCLUSIONIn order to reduce the incidence of DFA/DBMP, we should pay more attention to children with serious caries, and provide them individual behavior management for different ages and temperament.
