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).

A population-based study on the impact of orofacial dysfunction on oral health-related quality of life among Brazilian schoolchildren.

Objective: The aim of the present study was to assess the impact of orofacial dysfunction on oral health-related quality of life (OHRQoL) among Brazilian schoolchildren.

Material And Methods: A population-based study was conducted with 531 children aged eight to 10 years at schools in the city of Campo Magro, Brazil. The Brazilian version of the Child Perceptions Questionnaire (CPQ) was the outcome variable used to measure the impact on OHRQoL.

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. The children were clinically examined at school by two trained and calibrated examiners (Kappa = 0.

Oral Health-Related Quality of Life and Traumatic Dental Injuries in Young Permanent Incisors in Brazilian Schoolchildren: A Multilevel Approach.

Background: Traumatic dental injury (TDI) during childhood may negatively impact the quality of life of children.

Objective: To describe the association of oral health-related quality of life (OHRQoL) and domains (oral symptons, functional limitation, emotional- and social-well-being) of children with individual and contextual variables.

Methods: A cross-sectional study was performed using a representative sample of 1,201 schoolchildren, 8-10 years-old, from public and private schools of Belo Horizonte, Brazil.

Validity and Reliability of the Brazilian Version of the Rapid Estimate of Adult Literacy in Dentistry--BREALD-30.

Objective: The aim of the present study was to translate, perform the cross-cultural adaptation of the Rapid Estimate of Adult Literacy in Dentistry to Brazilian-Portuguese language and test the reliability and validity of this version.

Methods: After translation and cross-cultural adaptation, interviews were conducted with 258 parents/caregivers of children in treatment at the pediatric dentistry clinics and health units in Curitiba, Brazil. To test the instrument's validity, the scores of Brazilian Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) were compared based on occupation, monthly household income, educational attainment, general literacy, use of dental services and three dental outcomes.

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.

Oral manifestations and treatment of a child with Sjögren's syndrome.

Sjögren's syndrome (SS) is a chronic inflammatory systemic autoimmune disease affecting the exocrine, salivary and lacrimal glands. The condition occurs more often in adults and is rare in childhood. SS should be considered in the differential diagnosis of recurrent parotitis and keratoconjunctivitis sicca.

Validity and reliability of the Brazilian version of the psychosocial impact of dental aesthetics questionnaire.

Oral health-related quality of life (OHRQoL) is an important aspect of health outcomes and its assessment should be made using validated instruments. The psychosocial impact of dental aesthetics questionnaire (PIDAQ) is an OHRQoL instrument that assesses the psychosocial impact of dental aesthetics was developed and validated for use on young adults. The aim of the present study was to assess the reliability, validity, and applicability of the PIDAQ for young adults in Brazil.

Horizontal root fracture with displacement in the primary dentition.

Root fractures in the primary dentition are uncommon and little information is available concerning adequate treatment and prognosis. The most recently published guidelines recommend more invasive approaches but also discuss the need for further studies. This article examines how a horizontal root fracture in the primary dentition of a 3-year-old girl was treated by reducing the coronal fragment, followed by semi-rigid containment for 21 days.

Microleakage of an adhesive system used as a fissure sealant.

Aim: The aim of this study was to investigate the microleakage of pit and fissure sealants in primary teeth and to determine if multi-step methods should produce better results in terms of microleakage prevention.

Methods And Materials: A total of 40 intact primary molars were randomly assigned to one of four sealant groups: resin based sealant Ultraseal XT (US - Ultradent) (Group 1, n=10); adhesive system Scotchbond Multi Purpose Plus (SBMP - 3M/ESPE) used as a sealant (Group 2, n=10); primer (SBMP) and US (Group 3, n=10); and primer, bond (SBMP) and US (Group 4, n=10). After thermocycling (x700, 5-55 degrees C) all teeth surfaces were made impermeable with the exception of the occlusal surface.

Evaluation of the dental structure loss produced during maintenance and replacement of occlusal amalgam restorations.

The aim of this in vitro study was to evaluate four different approaches to the decision of changing or not defective amalgam restorations in first primary molar teeth concerning the loss of dental structure. Ditched amalgam restorations (n = 11) were submitted to four different treatments, as follows: Control group - polishing and finishing of the restorations were carried out; Amalgam group - the ditched amalgam restorations were replaced by new amalgam restorations; Composite resin group - the initial amalgam restorations were replaced by composite resin restorations; Flowable resin group - the ditching around the amalgam restorations was filled with flowable resin. Images of the sectioned teeth were made and the area of the cavities before and after the procedures was determined by image analysis software to assess structural loss.

Academic trajectories of dental researchers receiving CNPq's productivity grants.

The present study analyzed the profile of dental researchers receiving grants related to their productivity in research from the Brazilian National Research and Development Council (CNPq). Data collection was carried out in March 2008, using the Brazilian database for curriculum vitae (Lattes Format). There were 144 researchers registered in the database and linked to 25 institutions.
