The greater concordance in the diagnosis of MIH among monozygotic twins indicates a genetic influence, although environmental factors, such as family income and hemorrhage during pregnancy, are also associated with the occurrence of MIH.

The objective was to evaluate the history of traumatic dental injury (TDI) among children with and without autism spectrum disorders (ASD) at the Centro Integrado de Educação Especial (CIES), in Teresina, Brazil. The dental records of 228 children, 114 with ASD (SG = study group) and 114 without ASD (CG = control group), paired by age, gender and socioeconomic characteristics between January 2007 and September 2014 were reviewed. Data were analyzed using chi-square test and multivariate logistic regression (alpha = 5.0%). Dental trauma in SG was lower than in the CG (24.6% and 41.2%, respectively, p = 0.007). The risk of trauma was lower among males in SG (OR: 0.35; 95%CI: 0.18 to 0.67). The likelihood of TDI in SG was 3.17 higher in females than that of males (p = 0.040). The prevalence of TDI was lower in ASD individuals compared to controls. Dental trauma was higher among ASD girls than ASD boys.

Background Developmental enamel defects (DDE) represent one of the prevalent oral problems in childhood; however, few studies have evaluated its impact on quality of life in the children's own perception. Aim To evaluate the DDE impact on quality of life of 5‐year‐old children. Methods This cross‐sectional observational study assessed 566 children aged 5 years old, in Teresina, Piauí, Brazil, according to their self‐perceptions. Children answered the Pediatric Quality of Life Inventory™ Version 4.0 and Oral Health Scale. The dmft index, modified DDE index and Foster and Hamilton criteria were used to diagnose dental caries, DDE and malocclusion, respectively. A single examiner performed the clinical examination. Descriptive analyses and Poisson regression with robust variance were performed. Results The prevalence of DDE was 33.7%. For children's self‐reports, the presence of DDE had a negative association with oral health‐related quality of life (OHRQoL; PR 1.09, 95% CI 1.02‐1.15). Enamel hypoplasia had a negative impact on the physical function (PR 1.05; 95% CI 1.01‐1.10) and oral health (PR 1.06, 95% CI 1.01‐1.11) domains. Diffuse opacity had a negative impact on the social aspect (PR 1.09, 95% CI 1.02‐1.18). Conclusions Enamel defects had a negative impact on OHRQoL according to the self‐reports of the children.

Resumo O objetivo do estudo foi avaliar o impacto da cárie dentária na qualidade de vida de pré-escolares. A população foi constituída por pré-escolares com idade de 5 anos, matriculados em instituições públicas e privadas de Teresina, PI, Brasil. Instrumento de qualidade de vida validado para população brasileira (Pediatric Quality of Life Inventory - PedsQL™) foi aplicado para as crianças e responsáveis, além de questionário socioeconômico-demográfico para os responsáveis. No exame dentário o índice ceod foi utilizado para avaliar a experiência de cárie. Das 566 crianças examinadas, 50,2% apresentaram experiência de cárie. Foi observada associação entre experiência de cárie e pior qualidade de vida no domínio de saúde bucal na percepção das crianças (RR= 0,981; IC95% = 0,97-0,99) e dos pais (RR= 0,955; IC95% = 0,94-0,97). De acordo com a percepção das crianças, cárie em dentes posteriores foi associada a pior qualidade de vida no domínio capacidade física (RR= 0,985; IC95% = 0,97-0,99). Concluiu-se que experiência de cárie impactou negativamente na QVRSB (qualidade de vida relacionada à saúde bucal) no domínio saúde bucal da criança de acordo com a percepção das crianças e dos pais. Cárie localizada em molares impactou negativamente na QVRSB no domínio capacidade física segundo a percepção das crianças.

The objective was to determine the prevalence of molar incisor hypomineralization (MIH) among individuals between 7 and 15 years old infected or noninfected with human immunodeficiency virus (HIV). The study was conducted with 33 HIV-infected individuals (study group; SG) and 66 non-HIV-infected schoolchildren (control group; CG), paired by gender and age. Data collection was based on medical records (SG), a questionnaire for caregivers and oral examination for diagnosis of MIH (European Academy of Pediatric Dentistry criteria) and caries (DMFT index and ICDAS). Data were analyzed with Mann-Whitney, chi-square, and Fisher's exact tests and logistic regression. In SG, MIH (45.5%) and caries (87.9%) had higher prevalence. MIH was associated with use of protease inhibitors in SG (OR: 2.14; 95% CI: 1.21 to 3.77) and incubator need in CG (OR: 2.80; 95% CI: 1.71 to 9.10). HIV-infected patients had a higher prevalence of MIH and dental caries in the permanent dentition.

Oral hairy leukoplakia (OHL) is caused by the Epstein-Barr virus (EBV), which has been related to HIV infection. In situ hybridization (ISH) is the gold-standard diagnosis of OHL, but some authors believe in the possibility of performing the diagnosis based on clinical basis. The aim of this study is diagnose incipient lesions of OHL by EBV ISH of HIV-infected patients and the possible correlations with clinical characteristics of the patients. Ninety-four patients were examined and those presenting with clinical lesions compatible to OHL were submitted to biopsy prior to EBV ISH. Twenty-eight patients had lesions clinically compatible to the diagnosis of OHL, but only 20 lesions were confirmed by EBV ISH. The patients with OHL had a mean age of 41.9 years and were HIV-infected for 11.2 years, on average, including CD4 count of 504.7 cells/mm3 and log10 viral load = 1.1. Among the quantitative variables, there was a statistically significant correlation with age only (P = 0.030). In conclusion, the presence of OHL in patients with HIV/AIDS results in changes in the epidemiological characteristics of the disease, and this fact allied with subtle clinical-morphological features makes clinical diagnosis very difficult. Therefore, EBV ISH is important for a definitive diagnosis of OHL.

INTRODUCTION: Many people suffering from mental disorders fail to adequately perform self-care, especially in relation to personal hygiene and in particular to oral hygiene. For these individuals, the prevention and ongoing clinical monitoring are essential. OBJECTIVE: To investigate the oral diseases that most affect patients with mental disorders attended in the Dental College of the Federal University of Piauí (UFPI). METHODOLOGY: Patients treated during the 2nd half of 2011 and 1st half of 2012 were examined. The DMFT index was used for evaluation of dental caries and the CPI index for periodontal evaluation. The statistical analyzes were performed with SPSS (Statistical Package for the Social Sciences), version 18.0, using a descriptive statistics to determine averages, standard deviations and frequencies. RESULT: 67.50% of the 40 patients had contact with the surgeon dentist for over one year, 95% performed their own oral hygiene and 70% did not use dental floss. The average of DMFT was 14.18. Of the patients, 49.13% needed of restorations of one surface and 60% needed dental prosthesis. Moreover, 33.75% of sextants evaluated had periodontal pockets. CONCLUSION: It can be noticed that patients with mental illness have a high risk of developing oral disorders, however, few carriers visite a dental professional regularly. In addition, the delay to seek treatment and lack of staff training, lead to solutions often crippling.
