Estimation of toothpaste fluoride intake in preschool children.

The objective of this study was to estimate the intake of toothpaste fluoride used by children aged 2 to 6 years (n=87) treated at a hospital of a medium-sized city (Campina Grande, PB) in the Northeastern region of Brazil. Data regarding sociodemographic characteristics of families and children's toothbrushing were collected from questionnaire-based interviews with parents/guardians, and the amount of fluoride used during toothbrushing was estimated using a precision scale for assessment of the risk of dental fluorosis, considering a cutoff value of 0.07 mgF/kg body weight/day.

Use of glass ionomer cement containing antibiotics to seal off infected dentin: a randomized clinical trial.

Dental materials with antibacterial properties can prevent the harmful effects caused by oral cariogenic bacteria. This double-blind controlled clinical trial evaluated the performance of a glass ionomer cement (GIC) added with antibiotics for sealing infected dentin in atraumatic restorations of primary molars. The study enrolled 45 children (45 teeth) between 5 and 8 years of age, of both genders, divided into two groups: GC (n=22), where cavities were lined with a conventional GIC (Vidrion F) and GA (n=23), with cavities lined with Vidrion F added with 1% each of metronidazole, ciprofloxacin and cefaclor antibiotic.

Caries removal in primary teeth--a systematic review.

Objective: This systematic review addressed what the ideal limit is for removing carious tissue to address a caries lesion.

Method And Materials: The Medline, Cochrane, and PubMed databases were searched for abstracts of English-language articles published between 2000 and 2010 as well as randomized clinical trials about the total, partial, and/or nonmechanical removal of carious tissue in primary teeth. The analysis of the abstracts was performed individually by two reviewers.

Therapeutic potential of Brazilian fluoride varnishes: an in vivo study.

The aim of this study was to assess in vivo the therapeutic effect of three fluoride varnishes available in the Brazilian market on the performance of white spot lesions (WSL). The sample included 36 children aged 7 to 13 years old, with a total of 67 active WSL in permanent anterior teeth. The children were randomly divided into 3 groups, according to fluoride varnish used: FL- Fluorniz (n=24), DUO - Duofluorid XII (n=22) and DF - Durafluor (n=21).

[Prevalence of anterior open bite and overjet preschoolers in the city of Recife (PE, Brazil)].

The objective of this work was to verify the prevalence of malocclusions (anterior open bite, overjet) and its association with age, gender and type of school with a sample of 2,651 preschool children in the city of Recife, PE, Brazil. The children were seated in school chairs in the room of the day care/school for the clinical exam, children aging two years or less were assisted in the system knee-knee, through natural and artificial illumination. The dental protrusion was verified when the overjet was larger than 3 mm through periodontal probe in millimeters.

Therapeutic effect of two fluoride varnishes on white spot lesions: a randomized clinical trial.

The aim of this randomized clinical trial study was to evaluate the therapeutic effect of two varnish formulations (G1 = 5% NaF, G2 = 6% NaF + 6% CaF(2)) on the remineralization of white spot lesions (WSL). The sample was composed of 15 (7- to 12-year-old) children with 45 active WSL in anterior permanent teeth. The children were randomly divided into two groups providing 22 lesions for G1 and 23 for G2.

Prevalence of dental trauma in deciduous teeth of Brazilian children.

The aim of this study was to assess the prevalence of dental trauma as compared to the prevalence of dental caries in children aged 3-59 months. A cross-sectional study was carried out during the National Immunization Day for Polio in Recife, northeast Brazil. The sample comprised 3489 children under the age of 5.

Evaluation of different methods for monitoring incipient carious lesions in smooth surfaces under fluoride varnish therapy.

Background: There are only a few studies relating visual inspection methods and laser fluorescence when monitoring regression of incipient carious lesions.

Aim: The purpose of this study was to monitor incipient carious lesions in smooth surfaces under varnish fluoride therapy using visual inspection methods and laser fluorescence (LF).

Design: Active white spot lesions (n = 111) in upper front teeth of 36 children were selected.
