Factors associated with dental behaviour management problems in children aged 2-8 years in Beijing, China.

AIM This study determined the prevalence of children's dental behaviour management problems (BMP) in our clinic, investigated the influence of non-dental and dental background variables on BMP, and analysed the predictive power of these variables. DESIGN The study group included 209 children aged 2-8 years who received dental treatment. Interviews were conducted with accompanying guardians. Children's dental behaviour was rated by a modified Venham's clinical anxiety scale and a cooperative behaviour rating scale. Regression models were used to analyse behavioural and interview data and to calculate the power of background variables to predict children's dental behaviour. RESULTS During the first treatment, 29.7% of children displayed BMP. Four variables were found to predict BMP in 87.9% of cases. The risk factors for BMP were younger age, negative guardian expectations of the child's behaviour during treatment, anxiety or shyness around strangers, and presence of toothache. Children aged 2.5-3.5 years who attended kindergarten showed better dental behaviour than those who did not. CONCLUSIONS This study is the first to report BMP prevalence in mainland China. Our results indicate that a simple pre-treatment interview could provide data allowing the dentist to identify children with special dental behavioural needs.
