Mothers in Mosul, Iraq, did not have sufficient knowledge about the prevention and management of traumatic dental injuries. Intervention programmes should be considered to increase mothers' awareness regarding dental injuries.

Background: Children were compared to their siblings, cousins or peers regarding the eruption of their permanent teeth. Genetic and environmental factors can affect dental development and, therefore, the body mass index (BMI) could be considered as a factor that may influence dental development. Purpose: To determine any possible association between BMI and either dental caries or the eruption of permanent teeth (central incisor and molar). Methods: A cross-sectional study was completed for six-year-old school children. A total of 218 children (116 boys, 102 girls) from public elementary schools in Erbil City were entered into the study. Dental caries assessments were carried out using the WHO criteria for decayed, missing and filled primary teeth and indices (DMFT). BMI was used to classify obesity status. Results: Overall, 27.98% of the children were classified as overweight, 59.17% as normal and 12.84% as underweight. The DMFT was 5.247, while 12.39% of the children were caries-free. Conclusions: Children of normal weight had most permanent teeth erupted and a low caries index. Underweight children had fewer erupted teeth and a higher caries index. The complex relationship between body composition and oral health should be considered in paediatric patients.

Background: Dental injury and trauma are some of the most important public health concerns among school children that may require immediate management, as they could result in consequences affecting the child aesthetically, psychologically and socially. Purpose: The aim of this study was to determine the prevalence of dental trauma, the type of fracture, the most commonly affected tooth and the effect of gender on the occurrence of dental trauma. Methods: The methodology of this study was a cross-sectional survey consisting of a questionnaire and an oral examination which was conducted on 12-year-old public primary school children. Schools were selected from five different areas of Erbil city in Iraq. Results: The results indicate that 16.3% of the sample were affected with dental trauma in both genders. Maxillary central incisor was the most commonly affected tooth, and the majority of dental traumas were untreated. The most common type of dental trauma was simple enamel fracture. Conclusions: Child students are at great risk regarding dental trauma, which may affect their social activity especially within their school life.
