No association between periodontitis, preterm birth, or intrauterine growth restriction: experimental study in Wistar rats.

Background: The biologic plausibility of the possible association between periodontitis and adverse pregnancy outcomes has been assessed with the use of different experimental models. However, most experimental studies did not induce periodontitis in the animals but promoted an acute microbial challenge with selected periodontal pathogens or their products subcutaneous or intravenous or intraamniotic. The present study was then conducted to verify the biologic plausibility of such association by experimentally inducing periodontitis in Wistar rats.

[Sociodemographic and clinical aspects of quality of life related to oral health in adolescents].

Objective: To estimate the prevalence and to identify sociodemographic and oral health factors associated with the negative impact of oral health conditions on the quality of life in adolescents.

The objective of this study was to assess whether there were differences in oral health related quality of life (OHRQoL) between women connected to either predominantly home-based and work-based social networks.

Methods: A follow-up prevalence study was conducted on 1403 pregnant and post-partum women (mean age of 25.

Initial assessment of responsiveness of the P-CPQ (Brazilian Version) to describe the changes in quality of life after treatment for traumatic dental injury.

This study aimed to assess the responsiveness of the Brazilian version of the Parental-Caregiver Perception Questionnaire (B-P-CPQ) to describe changes in quality of life (QoL) after treatment for traumatic dental injury (TDI). After eligibility criteria were applied, 42 of 255 patients who went to a dental trauma center for TDI treatment were included. QoL was evaluated in two different appointments: A1 (after TDI) and A2 (after TDI treatment).

Evaluation of the subgingival microbiota of alcoholic and non-alcoholic individuals.

Objectives: The aim of this study was to evaluate the composition of the subgingival microbiota of alcoholic and non-alcoholic individuals.

Methods: The study was conducted with 49 alcoholic and 49 non-alcoholic males of the Philippe Pinel Institute, Rio de Janeiro, Brazil. The subjects were selected by convenience and two criteria were used to diagnose alcohol dependence: the CAGE (cut-down, annoyed, guilt, eyes-opener) questionnaire and the International Statistical Classification of Diseases, 10th edition (WHO).

Psychometric properties of the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS).

Background: Oral disorders can have a negative impact on the functional, social and psychological wellbeing of young children and their families and cause pain/discomfort for the child. Oral health-related quality of life (OHRQoL) has emerged as an important health outcome in clinical trials and healthcare research. The Early Childhood Oral Health Impact Scale (ECOHIS) is a proxy measure of children's OHRQoL designed to assess the negative impact of oral disorders on the quality of life of preschool children.

Oral health-related quality of life of 11- and 12-year-old public school children in Rio de Janeiro.

Objectives: The objective of this study was to assess the association between oral health-related quality of life (OHRQoL), measured through the Child-OIDP, and demographic characteristics, self-reported oral problems, and clinical oral health measures, among 11- to 12-year-old school children in the city of Rio de Janeiro, Brazil.

Methods: A cross-sectional study was conducted, having as its target population 11- and 12-year-old students of both sexes, formally enrolled in 6- and 7-year school classes at public schools. A probabilistic sample with complex design was used.

Periodontal bacterial load: a proposed new epidemiological method for periodontal disease assessment.

Aim: The purpose of this study was to identify a periodontal clinical measure that correlates with red complex bacteria usually associated with periodontal disease.

Methods And Materials: Periodontal clinical parameters were recorded in 116 postpartum women at six sites per tooth for all teeth excluding third molars. Two subgingival plaque samples per subject were collected and analyzed for 39 bacterial species using the Checkerboard DNA-DNA hybridization technique.

Child-OIDP index in Brazil: cross-cultural adaptation and validation.

Background: Oral health-related quality of life (OHRQoL) measures are being increasingly used to introduce dimensions excluded by normative measures. Consequently, there is a need for an index which evaluates children's OHRQoL validated for Brazilian population, useful for oral health needs assessments and for the evaluation of oral health programs, services and technologies. The aim of this study was to do a cross-cultural adaptation of the Child Oral Impacts on Daily Performances (Child-OIDP) index, and assess its reliability and validity for application among Brazilian children between the ages of eleven and fourteen.
