Oral habits, dental trauma, and occlusal characteristics among 4- to 12-year-old institutionalized orphan children in Riyadh, Saudi Arabia.

Abstract

The aim of this study was to assess the oral habit practices, dental trauma, and occlusal characteristics of 4- to 12-year-old orphans living in governmental orphanages in Riyadh. This cross-sectional study was conducted in three government orphanages and three ordinary schools. All 90 orphans, residing in the orphanage, were included. Ninety schoolchildren were selected to serve as the controls. Demographic data, oral habit history, and dental trauma history were obtained through a questionnaire. All children were examined to confirm the presence of signs of oral habits, dental trauma, and associated occlusal characteristics. Pearson chi-square was used for statistical analysis. Orphans were found to have more digit sucking and oral self-mutilation habits; however, the control children were found to have more nail biting habit. Nearly 21% of the orphans had dental trauma compared to 10% of the control group. About 70% of the dental trauma affected permanent teeth among orphans, whereas, 85% affected primary teeth in the control children. Dental trauma increased as the orphans got older; however, it decreased significantly as the control children got older. Orphans were found to have more cross-bite, increased over-jet, and open-bite. Digit sucking habit was positively associated with class II molar relation, presence of posterior cross-bite, and open-bite. Orphans had increased prevalence of digit sucking habit, self-mutilation, dental trauma, and malocclusion.
