Abstract Background: Parental factors have an important role in the behavior of the child in the dental clinic. These factors include parent-child relationship, parental dental anxiety, attitudes and perceptions regarding child’s behavior in the dental clinic, past dental experiences, presence in the dental operatory during treatment. Understanding the ways in which parents influence behavior will help the dentist in behavior guidance of the child during dental treatment. Aim: To investigate the relationship of the child's behavior and parenting styles during simple dental treatment. Study design: A crosssectional observational study was conducted in a private dental college. Parents of seventy seven children aged 4-12 years visiting a dental setting for restorative visits were asked to fill the questionnaire. The questionnaire consisted of demographic details (age, gender) and a Parenting Styles and Dimensions Questionnaire (PSDQ) followed by Frankl behaviour rating scale. The actual behaviour of the child was also recorded during the treatment session by a silent observer. Descriptive statistics along with chi square test were done to analyze the data and to know the level of significance of determinate which was set at less than 0.05. Results: There were 29 (37.66%), 22 (28.57%) and 23 (29.87%) children who had authoritative, authoritarian and permissive parents respectively. We observed significant differences in children’s behavior, according to the parenting styles. The authoritative parents had 2 and 14 children with definitely positive and positive behavior respectively while the authoritarian and permissive parenting styles had same number of children with definitely positive and positive behavior (n=1 and 10, respectively, in each) Conclusion: The evidence supports a relationship between parenting style and children’s dental behavior. However, this association was limited to children with no dental experience. Overall, regarding children’s behavior, we found that children with authoritative parents exhibited slightly more positive behavior compared to other parenting styles.
