Aim: This study aims to calculate the prevalence of parenting style in a group of children with primary dentition in their first dental visit. Materials and methods: This study was performed on 180 parents and their children who attended the diagnostic dental clinic in Pediatric Dentistry and Dental Public Health Department, Faculty of Dentistry, Cairo University, Egypt. Each parent filled out the Parenting style and dimension questionnaire (PSDQ). Each child was video-recorded during his first dental visit and later on, these videos were rated by two different examiners to determine their behavior according to Frankl scale. Results: From a group of parents with preschool children with a mean age of (4.43 ± 1.23) years, 121(67.2%) parents exhibited the authoritative parenting style, 53(29.4%) parents exhibited the permissive parenting style, and 6(3.3%) parents exhibited authoritarian parenting style. 52(43%) kids with authoritative parents showed definitely positive behavior while 27(50.9%) kids with permissive parents showed positive behavior. Conclusion: The prevalence of the authoritative parenting style was the highest while the authoritarian was the lowest. There was a significant influence of parenting style on child behavior in the dental office but there's no significant influence of parenting style on caries experience.
