Fluoridated water impact on tooth decay and fluorosis in 17-20-year-olds exposed to fluoride toothpaste.

Objective: To determine the impact of water fluoridation on the prevalence and severity of dental caries and fluorosis in individuals aged 17-20 years exposed to fluoride toothpaste.

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.

Enamel of Premolars whose Predecessors Presented Rupture of the Follicle Bone Crypt from Periapical Infections.

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.

Functional and esthetic rehabilitation of a child with amelogenesis imperfecta: a case report.

Amelogenesis imperfecta (AI) is a tooth disorder characterized by the abnormal development of the enamel in response to mutations in the genes involved in amelogenesis. The objective of this article is to present the clinical case of a child with AI in the primary dentition phase. A 4-year-old boy was presented to a clinic by his mother, who complained that her son's smile esthetics were compromised by "weak and yellow teeth.

Caries, Toothbrushing Habits, and Fluoride Intake From Toothpaste by Brazilian Children According to Socioeconomic Status.

Purpose: The purpose of this study was to evaluate the prevalence of dental caries, toothbrushing habits, fluoride intake, and factors associated with the use of toothpaste in Brazilian children according to socioeconomic status (SES).

Methods: A cross-sectional observational study was conducted with 148 three- to four-year-olds of both low and high socioeconomic status. Data collection consisted of administering a questionnaire to guardians, brushing to determine fluoride intake, and examining the children's teeth to evaluate dental caries.

Does Leishmaniasis disease alter the parenchyma and protein expression in salivary glands?

Leishmaniasis is considered a serious public health problem in several regions in Brazil and worldwide. This research aimed to perform a histopathological and proteomic study of parotid, submandibular and sublingual glands of BALB/c mice infected by Leishmania (L) infantum chagasi using histological, immunohistochemical and epifluorescence techniques. Twelve isogenic BALB/c male mice, around six- to eight-weeks old, were separated into two groups: the animals of the control group were injected with 0.

Restorative management of severely ankylosed primary molars.

Severe dentoalveolar ankylosis is an etiological factor for malocclusion. When infraocclusion occurs early, it progresses with time, leading to severe consequences in young children because of compensatory supra-eruption of the antagonist tooth and mesialization of adjacent teeth. Early diagnosis allows for interception of the problem and may prevent orthodontic treatment.
