Objective:The purpose of this study was to perform a clinical retrospective analysis of the etiology, incidence and treatment of selected oral and maxillofacial injuries in Brazilian children and adolescents.Materials and Methods:This study was conducted during a 14-year period between 1986 and 2000. All patients were admitted to Hospital XV in the city of Curitiba, State of Paraná. Age, gender, monthly distribution, etiology, soft injuries, associated injuries, site of fractures and methods of treatment were reviewed.Results:Of the total of 350 patients of all ages treated for facial injuries, 29.42% were within the age range of the study (0 to 18 years). Mean age was 10.61. Of the patients, 63.1% were male. The most common cause of injury was accidental falls (37.87%), followed by bicycle and motorcycle accidents (21.36%). Of the 103 patients, 88.34% had single injuries. Mandibular fractures were the most common and the condylar region was particularly affected.Conclusion:Facial trauma is a relatively common occurrence in children. The study indicates that fractures in children and adolescents differ quite considerably from an adult population.

Background/Aim Sleep quality exerts an influence on attention level and motor skills and is associated with accidental injuries in children. The aim of this study was to evaluate the association between traumatic dental injury and sleep behaviour in children. Material and Methods A cross‐sectional study was conducted in a small city in southern Brazil with a representative sample of schoolchildren aged 8‐10 years (n = 537). Weight and height were measured, and examinations were performed for the determination of clinical occlusion and traumatic dental injury. The parents answered the Sleep Behaviour Questionnaire and questions addressing socio‐demographic characteristics. Results The prevalence of traumatic dental injury was 22% (95% CI: 19‐26) and was higher among children who woke three to four times per night (PR = 3.30; 95% CI: 2.47‐4.39), those who fell asleep in the parental bed (PR = 1.41; 95% CI: 1.09‐1.83), those who were not in a good mood on waking up in the morning (PR = 1.30; 95% CI: 1.02‐1.65), those who became sleepy while sitting and/or studying (PR = 1.57; 95% CI: 1.09‐2.24) and while watching TV (PR = 1.41; 95% CI: 1.0005‐1.97) and those who had bad dreams (PR = 1.35; 95% CI: 1.04‐1.76). The Poisson multiple regression model with a multilevel approach revealed that the prevalence of traumatic dental injury was 1.51‐fold higher among children with daytime drowsiness (PR = 1.51; 95% CI: 1.11‐2.04) after adjusting for socio‐demographic, occlusal and anthropometric variables. Conclusion Sleep problems were associated with a higher prevalence of traumatic dental injury among the children analysed.

The aim of this study was to report two rare cases of ectopic tooth into the nasal cavity. The first case reports a 32-year-old female patient with the main complaint of having a tooth inside her nose. According to her, this condition causes pain and sporadic nosebleed. The patient had a facial trauma when she was 6 years old. The second case refers to an 8-year-old girl with left incomplete unilateral cleft lip and palate. The main complaint was left-sided nasal obstruction by a white hard mass. The treatment for both cases was surgical removal of the ectopic erupted tooth under general anesthesia. In conclusion, we can state that the surgical removal of intranasal tooth is a safe procedure and improves patient’s quality of life.
