Pre-, Peri-, and Postnatal Risk for the Development of Enamel Defects in Permanent Dentition: A Birth Cohort in Southern Brazil.

The purpose of this study was to find potential risk factors associated with the occurrence of developmental defects of enamel (DDE) in permanent dentition of a birth cohort in Southern Brazil. This study is a 2004 birth cohort carried out in the city of Pelotas, Rio Grande do Sul, Brazil. A subsample of 996 children was clinically examined at 12 to 13 years of age.

Validity of partial protocols to evaluate the prevalence of developmental defects of enamel in permanent dentition: a birth cohort study in Southern Brazil.

Objectives: To evaluate the validity of partial protocols (PP) to assess the prevalence of developmental defects of enamel (DDE) in permanent teeth and identify the strength of the association between DDE and some risk factors, using PP compared to the full-mouth (FM) exam.

Materials And Methods: This study was conducted in a population-based birth cohort of children born in 2004 in Pelotas, Southern Brazil. Socioeconomic, demographic, pre-, per-, and post-birth variables were collected.

Incidence and prognosis of crown discoloration in traumatized primary teeth: A retrospective cohort study.

Background/aim: Knowledge of factors influencing the occurrence of crown discoloration following traumatic dental injuries in primary teeth and understanding its possible consequences can help dentists to provide appropriate care. The aim of this retrospective cohort study was to investigate the incidence of crown discoloration following trauma in primary teeth. This study also estimated the risk of pulp necrosis with subsequent infection of the root canal system and pulp canal obliteration in discolored teeth.

Comparative Study of Dental Pain Between Children With and Without a History of Maltreatment.

Aims: To assess the presence of dental pain in child abuse victims and to compare the findings to children in the same age group with no history of abuse in a Southern Brazilian city.

Methods: This cross-sectional comparative study was carried out in a convenience sample of 68 child abuse victims from a center for psychologic support and in a comparative group of 204 students from public and private schools, all aged between 8 and 12 years. Data for socioeconomic and demographic variables were collected, and information regarding dental pain in the last 6 months was obtained via interviews with the children.

Is dental trauma more prevalent in maltreated children? A comparative Study in Southern Brazil.

Background: Although a high prevalence of head and neck trauma has been reported in maltreated children and adolescents, most of these studies focused on record-based analyses, and only a few used control groups.

Aim: To assess the presence of dental trauma in maltreated children in comparison with children without a history of maltreatment.

Design: A cross-sectional study with 68 maltreated children and 204 age, sex-, and school-matched control participants was conducted in Pelotas, a Southern Brazilian city.

The role of human milk and sucrose on cariogenicity of microcosm biofilms.

This study investigated the effect of human milk, alone and associated with sucrose, in the cariogenicity of biofilms in a microcosm biofilm model and compared with the cariogenicity of sucrose and bovine milk. Microcosm biofilms were grown in enamel discs in 24-well plates. Six growth conditions were studied: DMM (chemically defined artificial saliva - negative control), DMM with 1% of sucrose (DMM+s) (positive control), human milk with DMM, human milk with DMM+s, bovine milk with DMM, and bovine milk with DMM+s.

Health-related quality of life of maltreated children and adolescents who attended a service center in Brazil.

Purpose: This study's aim was to evaluate the health-related quality of life (HRQoL) and associated factors of maltreated children and adolescents.

Methods: This cross-sectional study consisted of individuals between 8 and 17 years of age who were victims of maltreatment. The KIDSCREEN-52 was used to measure their HRQoL.

Oral health-related quality of life in Brazilian child abuse victims: A comparative study.

This study aims to assess and compare Oral Health-Related Quality of Life (OHRQoL) in child abuse victims and non-abused children in a Southern Brazilian city. The study compared two independent samples of children aged 8-10 years: 48 child abuse victims recruited from a centre for Child and Adolescent Psychological Support (NACA) for abused children, and 144 public and private school students. Data collection consisted of administration of the Child Perceptions Questionnaire 8-10 (CPQ) to measure OHRQoL (dependent variable), clinical examination (dental caries), and collection of socioeconomic and demographic information (age, sex, skin colour, family income, and type of school).
