Methods: The study population consisted of 660 students from public schools, residents of areas supplied with fluoridated water (exposed group) or not (not exposed group). Students from both groups had access to fluoride toothpaste throughout life.

Quilombola children and adolescents show high prevalence of developmental defects of enamel.

Teeth with developmental defects of enamel (DDE) have porous and/or uneven enamel, making them more susceptible to the build-up of oral biofilm and development of caries and periodontal diseases. The aim of this cross-sectional study was to determine the prevalence of DDE and associated factors among children and adolescents living in a Quilombola community in the Northeast of Brazil. The study population was census-based and comprised individuals aged three to 14 years.

Hypomineralized Teeth Have a Higher Frequency of Dental Hypersensitivity.

The purposes of this study were to: (1) compare dental hypersensitivity (DH) between hypomineralized permanent first molars and unaffected controls molars in patients with molar-incisor hypomineralization (MIH); and (2) assess the influence of opacity, color, and subject age on DH. This cross-sectional study identified 40 children/adolescents, who were attending a children's dental clinic and had one to three first permanent molars hypomineralized (demarcated opacities). The severity and color of the hypomineralized lesions were also evaluated.

Does low-cost GIC have the same survival rate as high-viscosity GIC in atraumatic restorative treatments? A RCT.

Atraumatic Restorative Treatment (ART) is one of the strategies used to control dental caries; it involves hand instruments for removal of carious tissue, and restorations using high-viscosity Glass Ionomer Cement (GIC). The present controlled clinical trial aimed to evaluate the performance of low-cost GIC indicated for ART in primary teeth, compared with high-viscosity GIC, after one year of follow-up. Two-to six-year-old children with dentin caries lesions on one or two surfaces of anterior and posterior teeth were selected.

Pre-term birth and asthma is associated with hypomineralized second primary molars in pre-schoolers: A population-based study.

Background: Hypomineralized second primary molar (HSPM) is a developmental enamel defect that represents a caries-risk factor. There are few studies about HSPM epidemiology in representative populations.

Aim: To determine the prevalence and factors associated with HSPM in pre-schoolers.

Impact of dental caries on the quality of life of preschoolers measured by PedsQL questionnaire.

The objective of this study was to evaluate the impact of dental caries on the quality of life of preschool children. The population was made up of preschoolers aged 5 years, enrolled in public and private institutions of Teresina, PI, Brazil. The Pediatric Quality of Life Inventory (PedsQL™) was applied to children and caregivers, as well as a socioeconomic-demographic questionnaire for those responsible.

Background: Developmental enamel defects (DDE) represent one of the prevalent oral problems in childhood; however, few studies have evaluated its impact on quality of life in the children's own perception.

Aim: To evaluate the DDE impact on quality of life of 5-year-old children.

Methods: This cross-sectional observational study assessed 566 children aged 5 years old, in Teresina, Piauí, Brazil, according to their self-perceptions.

Cellular profile of primary molars with pulp necrosis after treatment with antibiotic paste.

The interradicular region of primary molars is permeated by many foramina, channels and accessories that connect the pulp cavity with the periapical tissues anatomically. Thus, pulp decomposition products or drugs used in endodontic treatment can trigger inflammatory reactions. The aim of this study was to evaluate the blood cell profile of the alveolar region after extraction of primary molars treated with CTZ paste.
