Influence of active versus passive parental presence on the behavior of preschoolers with different intelligence levels in the dental operatory: a randomized controlled clinical trial.

Background: Dental fear and anxiety still pose the most common factors proposed for the child's negative behavior in the dental operatory. Intelligence has an impact on the children's communication, feelings, and responsiveness to dental situations. The benefits of parental presence on reinforcing the child's behavior during dental treatment are still debatable.
