Association between psychosocial determinants of adverse childhood experiences and severe early childhood caries among First Nations children.

Aim: To determine whether psychosocial determinants of adverse childhood experiences (ACE), from pregnancy to 2 years old, are associated with severe early childhood caries (S-ECC) in Indigenous children.

Design: Secondary data analyses from an ECC prevention trial among 344 First Nations mother-child dyads living on- and off-reserve in Ontario and Manitoba, Canada. Stratified (on-/off-reserve) logistic regression, controlling for mother's age and income source, assessed three categories of psychosocial ACE determinants: alcohol/drug misuse, household financial hardship (overcrowding and food insecurity) and emotional/social well-being (Perceived Stress Scale (PSS-14), sense of personal control (SOC), social support, subjective social status).

Oral health literacy and oral health outcomes in an adult population in Brazil.

Background: To investigate the association between critical and communicative oral health literacy (OHL) and oral health outcomes (status, oral health-related quality of life and practices) in adults.

Methods: This cross-sectional study examined a household probability sample of 248 adults, representing 149,635 residents (20-64 years old) in Piracicaba-SP, Brazil. Clinical oral health and socioeconomic and demographic data, as well as data on oral health-related quality of life (OHIP-14) and health practices were collected.

[Tooth loss classification: factors associated with a new classification in an adult population group].

This study evaluated tooth loss and factors associated with a new classification, which considers not only the number of teeth lost, but also the number and position that they occupied in the mouth. In Piracicaba, State of São Paulo, Brazil, 248 adults (20-64 year-olds) were examined using a household probability sample. The oral examinations followed the WHO criteria for caries and periodontal disease.

Impact of tooth loss related to number and position on oral health quality of life among adults.

Background: The objective of this study was to evaluate the impact of tooth loss on oral health-related quality of life (OHRQoL) in adults with emphasis on the number of teeth lost and their relative position in the mouth.

Methods: The study population was a cross-sectional household probability sample of 248, representing 149,635 20-64 year-old residents in Piracicaba-SP, Brazil. OHRQoL was measured using the OHIP-14.
