Impact of bone-anchored maxillary protraction on the quality of life of subjects with complete unilateral cleft lip and palate.

INTRODUCTION: This study aimed to evaluate the influence of bone-anchored maxillary protraction (BAMP) on the oral health-related quality of life (OHRQOL) in subjects with complete unilateral cleft lip and palate (UCLP) and moderate-to-severe maxillary deficiency. METHODS: A longitudinal observational study was conducted with a sample of 20 patients (13 males, 7 females) aged 10-14 years (mean age, 11.8 years) with Goslon 3, 4, and 5. To assess the patient's perception of their OHRQOL, the Quality of Life Questionnaire for Orthosurgical Patients was administered in 2 stages: after the installation of the protraction plates (T1) and 18 months after the protraction therapy started (T2). The questionnaire was composed of 4 domains, distributed over 22 questions: social aspects, facial esthetics, oral function, and awareness of facial deformity. RESULTS: The treatment protocol improved the OHRQOL in 75% of the patients who presented UCLP. The domain social aspects of the deformity were the only one that showed a significant difference from T1 to T2 and indicated an improvement in self-esteem. The girls had worse OHRQOL than boys at T1, which was statistically significant only for the domains of social aspects of deformity and awareness of deformity. After BAMP therapy, the effect size indicated a larger change in OHRQOL in girls than in boys. CONCLUSIONS: BAMP therapy positively impacted the OHRQOL and self-esteem of patients with UCLP during adolescence.

Self-perceived malocclusion of non-orthodontic patients affects oral health-related quality of life?

Purpose: This cross-sectional study evaluates the impact of self-perceived malocclusion on oral health-related quality of life (OHRQoL) and also whether aesthetic self-assessment is similar to professional evaluation. Methods : this cross- sectional study gathered 63 adults aged 18­36 years (28.68 ± 4.99), 42 women and 21 men, with no history of orthodontic treatment. OHRQoL was evaluated using the Brazilian short version of the Oral Health Impact Profile questionnaire (OHIP- 14). Perception of malocclusion was evaluated using the aesthetic component of the Index of Complexity, Outcome and Need (ICON), socioeconomic status and the Economic Classification Criteria of Brazil. Statistical analysis was conducted using the Mann­Whitney test, Spearman correlations and Wilcoxon test, with p < 0.05. Results : the overall average score and standard deviation for OHIP-14 was 5.17 (± 6.50). There was a weak correlation between the aesthetic component perceived by the participants and their evaluation of quality of life. Only the psychological domains (psychological discomfort and psychological disability) showed significant poor correlations. Gender and socioeconomic status did not affect aesthetic perception of malocclusion and OHRQoL. There was a significant difference between the professional assessments and those of participants. Conclusion : significant weak correlations between self- erceived malocclusion and OHRQoL were found in participants who were not seeking orthodontic treatment; the greatest impacts were seen in the domains of psychological discomfort and psychological disability, and aesthetic self-perceived malocclusion was significantly less relevant than the professional evaluation in this studied group.

Objetivo: Este estudo transversal teve como objetivo avaliar o impacto da má oclusão autopercebida na qualidade de vida relacionada à saúde bucal (OHRQoL) e também avaliar se a autoavaliação estética é semelhante à avaliação profissional. Métodos : Foram avaliados 63 adultos com idades entre 18 e 36 anos (28,68 ± 4,99), 42 mulheres e 21 homens, sem histórico de tratamento ortodôntico. A OHRQoL foi avaliada utilizando a versão brasileira do questionário Oral Health Impact Profile (OHIP-14). A percepção da má oclusão foi avaliada utilizando-se o componente estético do Índice de Complexidade, Resultado e Necessidade (ICON) e o nível socioeconômico foi avaliado com os Critérios de Classificação Econômica do Brasil. A análise estatística foi realizada pelo teste de Mann-Whitney, correlações de Spearman e teste de Wilcoxon, com p<0,05. Resultados : A pontuação média geral e desvio padrão para o OHIP-14 foi de 5,17 (±6,50). Houve fraca correlação entre o componente estético percebido pelos participantes e a avaliação de sua OHRQoL. Apenas os domínios psicológicos (desconforto psicológico e incapacidade psicológica) apresentaram correlações significativas, porém pobres. O sexo e o nível socioeconômico não afetaram a percepção estética da má oclusão e a OHRQoL. Houve diferença significativa entre as avaliações profissionais e dos participantes. Conclusão : Correlações fracas e significativas entre a má-oclusão autopercebida e a OHRQoL foram encontradas em participantes que não procuravam tratamento ortodôntico, onde os maiores impactos foram observados nos domínios desconforto psicológico e incapacidade psicológica. A má-oclusão estética percebida pelos participantes foi significativamente menos relevante do que a avaliação profissional neste grupo estudado.

Craniofacial characteristics of patients with heart disease.

INTRODUCTION: Children with congenital heart disease commonly experience delayed growth. Studies comparing growth and development of these children generally found that they have decreased height and weight, but with no information on craniofacial growth. The aim of this study was to evaluate the craniofacial characteristics of patients with heart disease. METHODS: We used lateral head cephalograms of 131 patients, aged 8 to 12, attending the Department of Pediatrics of the Hospital of the State University of Rio de Janeiro in Brazil on a routine basis. The study group comprised 50 boys and 38 girls with congenital heart disease. The control group included 20 boys and 23 girls with no heart disease. The skeletal, dental, growth, esthetic, and vertical patterns were analyzed with several cephalometric measurements. The chi-square test was applied to verify a possible association between sex and heart disease, and the Student t test was used to verify differences between the groups of patients with and without heart disease. RESULTS: Heart disease is not sex-related (chi-square = 0.267). But some measurements had sex differences in the groups with and without heart diseases. The Student t test showed significant differences between the groups in the SNA angle measurement in male patients (P = 0.032), and in ANB angle (P = 0.002) and the relationship of the lower lip to the Steiner line (P = 0.034) in the girls. CONCLUSIONS: Skeletal patterns were characterized by maxillary protrusion in the boys with heart disease and by increased ANB angles in the girls without heart disease. The esthetic pattern showed a more pronounced lower lip in the girls without heart disease. However, from a clinical point of view, these were slight and irrelevant alterations. The results suggest that patients suffering from heart disease have similar craniofacial characteristics to those without this condition.

Influência do pré-estiramento nas forças geradas por elásticos ortodônticos em cadeia / Influence of pre-stretch in the forces generated by orthodontic elastic chains

O objetivo deste estudo foi avaliar a influência dos procedimentos de estiramento de forma única e múltiplanas velocidades de 5,0 mm/minuto e 50,0 mm/minuto no grau de de gradação da força gerada por elásticos em cadeia na cor cinza da marca comercial American Orthodontics . Os elásticos foram estirados em umamáquina de ensaios de tração e pelo método manual com pinça de separação e mantidos imersos em águadestilada, onde permaneceram distendidos em 50% de seus comprimentos por 48 horas. Tiveram suas forças medidas em uma máquina de ensaios de tração (EMIC-DL 500 MF célula 1 Kgf) e os resultados foram gerados por um computador conectado à máquina de tração e foram submetidos a testes estatísticos (ANOVAe GLIM) com p < 0,05. Os resultados demonstraram que não houve diferença estatisticamente significativaem relação ao método de estiramento realizado de forma única e múltipla e em relação à velocidade de estiramentorealizada de forma lenta e rápida. Foram encontradas diferenças significativas com maior degradação da força para os elásticos estirados em máquina de ensaio de tração em relação aos estirados pelo método manual com pinça de separação com p < 0,001. Concluiu-se que em termos práticos, o procedimento de pré-estiramento dos elásticos em cadeia poderá ser realizado de forma única e na velocidade rápida e que o método de estiramento manual com pinça de separação mostrou-se efetivo, liberando forças nos níveisaceitáveis clinicamente para a movimentação dentária.
