Prevalence of and factors associated with enamel fracture and other traumas in Brazilian children 8-10 years old.

The aim of this study was to assess the prevalence and discriminate the associated factors between enamel fractures and other trauma/trauma sequelae in 8 to 10-year-old Brazilian schoolchildren. A representative sample of 1,201 children from public and private schools were enrolled in this cross-sectional study. Questionnaires about sociodemographic characteristics were answered by parents.

Impact of malocclusion on the quality of life of children aged 8 to 10 years.

Objective: The aim of the present cross-sectional study was to assess the impact of malocclusion on the quality of life of children aged 8 to 10 years attending public elementary schools in Belo Horizonte, State of Minas Gerais, Brazil.

Methods: The Brazilian version of the Child Perceptions Questionnaire 8-10 (CPQ8-10) was used to evaluate oral health-related quality of life. The children were examined for the diagnosis of malocclusion using the Dental Aesthetic Index (DAI).

Dental caries remains as the main oral condition with the greatest impact on children's quality of life.

Purpose: The objective of this study was to assess the negative impact of dental caries on the OHRQoL of 8- to 10-year-old Brazilian children.

Methods: This population-based case-control study involved 546 children (8-10 years old), 182 cases with a high negative impact on OHRQoL and 364 controls with a low negative impact on OHRQoL. Children's OHRQOL was measured using the Child Perceptions Questionnaire (CPQ8-10).

Bird and ant synergy increases the seed dispersal effectiveness of an ornithochoric shrub.

Seed dispersal may involve different vectors of dispersal in two or more sequential phases (i.e., diplochory).

Dental caries and social factors: impact on quality of life in Brazilian children.

The objective of this study was to evaluate the impact of dental caries and social determinants in the Oral Health Related Quality of Life (OHRQoL) of children in Belo Horizonte, Brazil. This is a population-based cross-sectional study with a representative sample of 1,204 children aged 8 to 10 years randomly selected from 19 public and private schools.

Base of the skull morphology and Class III malocclusion in patients with unilateral cleft lip and palate.

Objective: The aim of the present study was to determine the morphological differences in the base of the skull of individuals with cleft lip and palate and Class III malocclusion in comparison to control groups with Class I and Class III malocclusion.

Methods: A total of 89 individuals (males and females) aged between 5 and 27 years old (Class I, n = 32; Class III, n = 29; and Class III individuals with unilateral cleft lip and palate, n = 28) attending PUC-MG Dental Center and Cleft Lip/Palate Care Center of Baleia Hospital and PUC-MG (CENTRARE) were selected. Linear and angular measurements of the base of the skull, maxilla and mandible were performed and assessed by a single calibrated examiner by means of cephalometric radiographs.

Malocclusion and oral health-related quality of life in Brazilian school children.

Objective: To test the hypothesis that malocclusion and its impact on quality of life has no effect on 8- to 10-year-old Brazilian schoolchildren as measured by an oral health-related quality of life (OHRQoL) instrument.

Materials And Methods: A cross-sectional study was carried out with a population-based sample of 1204 8- to 10-year-old children attending elementary schools in Belo Horizonte, Brazil. Dental examinations were carried out by two calibrated examiners.

Orthodontic treatment of a child with Crigler-Najjar syndrome type I using tacrolimus following liver transplantation.

The present study reports the orthodontic treatment of a child with Crigler-Najjar syndrome type I following a liver transplant and administration of tacrolimus (1 mg/day). Tacrolimus (FK506) is fundamental to immunosuppression following transplantation. The child exhibited Class II division 1 malocclusion.

Prevalence and determinant factors of malocclusion in children with special needs.

Careful attention to malocclusion in children with special needs leads to a considerable improvement in the quality of life. The present study analysed the prevalence of malocclusion in children with Down syndrome (DS) and cerebral palsy (CP) as well as associations with individual, socio-economic, and behavioural factors. A cross-sectional study was carried out that included 181 mothers and their children with DS and CP (aged 3-12 years) at two institutions for individuals with special needs in Rio de Janeiro, Brazil.

Feeding and nonnutritive sucking habits and prevalence of open bite and crossbite in children/adolescents with Down syndrome.

Objective: To analyze the influence of breastfeeding, bottle feeding, and nonnutritive sucking habits on the prevalence of open bite and anterior/posterior crossbite in children with Down syndrome (DS).

Materials And Methods: A cross-sectional study was carried out in 112 pairs of mothers/children with DS between 3 and 18 years of age at a maternal/children's hospital in Rio de Janeiro, Brazil. The children with DS were clinically examined for the presence of open bite as well as anterior and posterior crossbite.

Orthodontic treatment for adults--dental displacement: a case report.

A growing number of adults are seeking orthodontic treatment. These patients require a different treatment approach than younger patients receive. Treatment of adult patients with dental-skeletal and facial abnormalities is not restricted to surgical correction alone; it also involves dental displacement.

Fruit diet of Alouatta guariba and Brachyteles arachnoides in Southeastern Brazil: comparison of fruit type, color, and seed size.

Fruit is an important food resource for neotropical primates. In this study I compare the fruit diet of sympatric brown howlers (Alouatta guariba) and southern muriquis (Brachyteles arachnoides). Feeding behavior was studied over 12 months and fruit species consumed were identified and assigned to the categories fruit type, fruit color, and seed size.
