Ankyloglossia and Breastfeeding Duration: A Multicenter Birth Cohort Study.

The prevalence of ankyloglossia and its impact on breastfeeding practices may be overestimated, leading to surgical overtreatment in newborns. The study was conducted to estimate the prevalence of ankyloglossia in the first year of life and investigate the association with exclusive and total breastfeeding duration in different regions of Brazil. This multicenter prospective cohort study involved the recruitment of mother-infant pairs soon after childbirth in public hospitals in three state capitals in Brazil.

Primary Dentition Caries Patterns as Predictors of Permanent Dentition Caries: A Prospective Cohort Study.

The aims of this study were to estimate the risk of caries in the permanent teeth at 12 years of age and to describe the diagnostic accuracy of caries patterns in the primary dentition at age 4 years to predict caries at age 12 years. A prospective cohort study followed children from birth to age 12 years in the city of São Leopoldo, Brazil. Sociodemographic variables were collected at birth, and dental caries was measured at 4 and 12 years of age (n = 204).

Exploring the risk factors for early-life sugar consumption: A birth cohort study.

Background: Sugar consumption in early childhood is the primary cause of negative health outcomes, including early childhood caries.

Aim: To investigate risk factors associated with early-life sugar consumption.

Design: Explanatory variables were collected at baseline of a birth cohort in Porto Alegre, Southern Brazil.

Feeding frequency in infancy and dental caries in childhood: a prospective cohort study.

Objectives: Feeding patterns in infancy are plausible contributors to dental caries later in childhood, yet relatively few cohort studies have examined potential dietary risk factors at this age. This study aimed to investigate the associations between feeding frequency at age 12 months and caries prevalence at age 3 years.

Methods: In this prospective birth cohort of 345 Brazilian children, all foods and drinks consumed at age 12 months, including bottle-use and breastfeeding, were recorded using two 24-hour infant dietary recalls with mothers.

Oral health-related quality-of-life scores differ by socioeconomic status and caries experience.

Objectives: (i) Quantify the relative association between child dental caries experience and maternal-reported child oral health-related quality of life (OHRQoL); (ii) examine whether that association differed according to family socioeconomic status (SES); and (iii) explore whether absolute OHRQoL varied by family SES at similar levels of child caries experience.

Methods: This study was a cross-sectional analysis of children in southern Brazil (n=456, mean age: 38 months) participating in an existing health centre-based intervention study. OHRQoL impact was quantified as mean score on the Brazilian Early Childhood Oral Health Impact Scale (ECOHIS) and compared over categories of caries experience (dmft: 0, dmft: 1-4, dmft: ≥5).

Feeding practices in infancy associated with caries incidence in early childhood.

Background: Early-life feeding behaviors foretell later dietary habits and health outcomes. Few studies have examined infant dietary patterns and caries occurrence prospectively.

Objective: Assess whether patterns in food and drink consumption before age 12 months are associated with caries incidence by preschool age.

Exploring the impact of oral diseases and disorders on quality of life of preschool children.

Objective: To assess the impact of oral health outcomes on Oral Health-Related Quality of Life (OHRQoL) in a school-based sample of Brazilian preschool children and their families.

Methods: A cross-sectional study was conducted in 1036 children aged 2-5 years attending all the public nurseries in Canoas, Brazil. Caregivers were asked to complete questionnaire on socioeconomic status and the Early Childhood Oral Health Impact Scale (ECOHIS) on their perception of the children's OHRQoL.
