Objective: To identify factors associated with the quality of oral hygiene in children with mental disabilities. Methods: A cross-sectional study was conducted with a sample of 181 mentally disabled children aged three to 12 years and their mothers. The study was conducted in two public hospitals of medical care for special children in the city of Rio de Janeiro, southeastern Brazil. The children were examined on the quality of oral hygiene and presence of caries lesions. The examiner was previously calibrated and were obtained kappa values of 0.90 to 0.87 for tooth decay and oral hygiene. The mothers answered a questionnaire addressing individual characteristics, behavioral and medical history of children. The study was approved by the Ethics Committee of UFMG. Data were analyzed using the chi-square test and multivariate logistic regression, considered to be a significant 90.0%. Results: Most of the children had mild intellectual disability (56.4%) and 43.6% had moderate mental disability. The quality of oral hygiene was considered adequate in 84.0% of children. A total of 172 mothers said that her son's teeth were brushed daily (95.0%). Among them, the majority reported difficulties in this task (53.0%). Those children diagnosed with mild intellectual disability {OR=2.82 [90% CI (1.15 to 6.86)]} and the absence of decay {OR=7.68 [90% CI (3:03 to 19:45)]} were more likely they belong to the group of children identified with an adequate oral hygiene. Conclusion:The quality of oral hygiene was associated with tooth decay and the degree of mental disability of children.

Objective: To evaluate whether individuals with osteogenesis imperfecta (OI) are more affected by malocclusion than individuals without OI. Materials and Methods: Searches in PubMed, Ovid, Web of Science, Scopus, Lilacs and gray literature were performed. Data extraction was conducted by two researchers. Risk of bias assessment employing the Newcastle-Ottawa Scale and meta-analysis were conducted. Results were provided with mean difference (MD), odds ratio (OR) and 95% confidence interval (CI). Strength of evidence was determined. Results: Six cross-sectional studies were included. In comparison with individuals without OI, the group with OI had 19.69-fold greater chance of exhibiting Angle Class III malocclusion (OR = 19.69, CI: 9.00-43.09) and presenting anterior crossbite greater (MD = 6.08, CI: 2.40-9.77). Individuals without OI had a significantly greater ANB angle (MD = 3.88, CI: 1.15-6.61) and SNA angle (MD = 2.11, CI: 0.24-3.98) in comparison with those with OI. No difference between groups was found for SNB (MD = −0.50, CI: −2.21 to 1.21) and open bite (MD = 0.98, CI: −0.29 to 2.25). Most studies included had moderate methodological quality. Strength of evidence was low or very low. Conclusions: The occurrence of Angle Class III malocclusion and anterior crossbite was greater among individuals with OI compared to those without OI. These findings can assist stakeholders about the occlusal abnormalities affecting OI individuals.

School health promotion programs can reduce common health problems like obesity, diabetes and respiratory complications. This qualitative study aimed to investigate the perceptions of a group of teachers regarding issues related to the promotion of health in school. The 15 teachers sampled were from public primary schools in a city in southeastern Brazil. Interviews with teachers were conducted and data was analyzed employing content. Teacher practices regarding the promotion of health appeared to be aimed at their students and their daily habits and their practices. Teachers described approaching health promotion through their lesson content and suggested that the school should seek help from other institutions in their health promotion activities like prevention activities, monitoring of improvements in student and teacher health. Teachers mentioned a strong relationship between knowledge and the pursuit of good health. The need to identify major determinants of the disease/health process was highlighted and the connection between lifestyle, socio-economic status and the disease/health process was described. Awareness of the influence concerning both the environment and the school surroundings was demonstrated. It is important that the teachers are aware of the environment that surrounds them as well as the reality of the lives of all those involved with the school.

Objective: While the process of social inclusion have promoted respect for the person with mental disability, the stigma against this individual is still very present in society, so that individual identified from their difference, now identified as being a weak, fragile and sometimes abnormal and identified as someone with a determination that can break barriers, even the difference. Considering that the social integration of individuals with disabilities still means a great challenge for society, this study sought to discuss issues related to targeted assistance to the population with mental disabilities within this integration process. The way society perceives and relates to people with disabilities is a repetition of the speech and behavior of its own professionals and programs involved in social integration and rehabilitation of these individuals.Conclusion: The educational institutions of human resources, and assistance programs aimed at the disabled, need to promote reflections on the densest kind of discourse and practices used in everyday life of these people and their families. They should not act based on rejudice.

Osteogenesis imperfecta is a rare genetic disorder involving abnormal type I collagen composition that compromises bone and collagen-rich tissues. Individuals with Osteogenesis imperfecta exhibit oral and systemic abnormalities, including dentinogenesis imperfect. The purpose of the review is to report a clinical case of a nine-year-old boy diagnosed with Osteogenesis Imperfecta type III, focusing on dental and occlusal aspects. The case report was developed at the outpatient clinic at the School of Dentistry of the Federal University of Minas Gerais, in Southeastern of Brazil. The clinical oral examination revealed Angle Class III malocclusion and anterior crossbite. It was also observed the presence of dentinogenesis imperfect in both primary and permanent teeth. Radiographic analysis showed the presence of completed obliterated pulp chambers in both dentitions. Dental treatment included oral hygiene counseling, dental extraction, fluoride therapy and restorations. The child was followed up for a period of six years and then referred to the orthodontic outpatient clinic at the same university for the treatment of malocclusion. Early dental care is important to the prevention or interception of oral diseases, such as dentinogenesis imperfect and malocclusion, as well as the improvement of dental esthetics in cases of Osteogenesis Imperfecta.
