Caries lesion transition patterns of schoolchildren in a fluoridated community in Brazil.

Objective: To describe the caries lesion transition pattern in permanent tooth surfaces over 2 years among a convenience sample of children in a fluoridated (0.8 ppm F) low-socioeconomic community of Brazil.

Material And Methods: One hundred forty-nine schoolchildren (7-12 years) were examined for caries using Nyvad criteria at baseline and after 2 years.

Reliability and validity of a new classification of MIH based on severity.

Objectives: To describe a new molar-incisor hypomineralization (MIH) severity scoring system (MIH-SSS) that focuses on the defects' severity and to assess the system's validity and reliability over 3 years.

Materials And Methods: One hundred eighty-one children diagnosed with MIH were examined by MIH-SSS. For reliability assessment, 15-20 children were examined twice, and analyses were performed at the tooth level at four different cutoff points.

Mechanical and optical properties of conventional restorative glass-ionomer cements - a systematic review.

Objectives: To perform a systematic review of test methodologies on conventional restorative glass-ionomer cement (GIC) materials for mechanical and optical properties to compare the results between different GICs.

Material And Methods: Screening of titles and abstracts, data extraction, and quality assessments of full-texts were conducted in search for in vitro studies on conventional GICs that follow the relevant specifications of ISO standards regarding the following mechanical and optical properties: compressive strength, flexural strength, color, opacity and radiopacity.

Sources: The Latin American and Caribbean Health Sciences (LILACS), Brazilian Bibliography of Dentistry (BBO) databases from Latin-American and Caribbean System on Health Sciences Information (BIREME) and PubMed/Medline (US National Library of Medicine - National Institutes of Health) databases were searched regardless of language.

Dental caries lesions in primary teeth without obvious cavitation: Treatment decision-making process.

Background: Dental caries diagnosis and management have changed over time.

Aim: To identify the treatment decision-making process performed by paediatric dentists, after caries detection using CAST instrument (Caries Assessment Spectrum and Treatment), for enamel (CAST 3) and non-cavitated dentin caries lesions (CAST 4) before and after analysing radiographic images.

Design: Seventy-four paediatric dentists were invited to participate.

Glass hybrid restorations as an alternative for restoring hypomineralized molars in the ART model.

Background: This study aimed to evaluate the survival rate of glass hybrid restorations placed under the atraumatic restorative treatment (ART) technique in first permanent molars affected by molar incisor hypomineralization (MIH).

Methods: Sixty teeth with severe MIH associated to carious dentin lesions without pulp involvement were included. Treatments were performed by one trained dentist using the ART approach and restored with a glass hybrid restorative system (Equia Forte, GC®) on school premises.

Retention rates and caries-preventive effects of two different sealant materials: a randomised clinical trial.

Objectives: The aim of this study was to compare the caries-preventive effect and the retention rates of sealants prepared with a new modified and a high-viscosity glass-ionomer cement (GIC) in recently erupted first permanent molars.  MATERIALS AND METHODS: Fifty-six children (224 teeth) were included in a split-mouth randomised clinical trial. All children had their four first permanent molars sealed with either Clinpro XT Varnish (CXT) or Fuji IX GP FAST (FJ).

Are Hypomineralized Primary Molars and Canines Associated with Molar-Incisor Hypomineralization?

Purpose: The purpose of this study was to evaluate the prevalence of and relationship between hypomineralized second primary molars (HSPM) and hypomineralized primary canines (HPC) with molar-incisor hypomineralization (MIH) in 1,963 schoolchildren.

Methods: The European Academy of Paediatric Dentistry (EAPD) criterion was used for scoring HSPM/HPC and MIH. Only children with four permanent first molars and eight incisors were considered in calculating MIH prevalence (n equals 858); for HSPM/HPC prevalence, only children with four primary second molars (n equals 1,590) and four primary canines (n equals 1,442) were considered.

Caries Experience in Children with and without Molar-Incisor Hypomineralisation: A Case-Control Study.

Aim: The aim of this study was to compare the caries experience of children with and without molar-incisor hypomineralisation (MIH).

Methods: A case-control study was designed in which 130 children aged between 7 and 13 years with MIH (cases) were matched with 130 children without the condition (controls) according to age, sex, and school. Dental caries and MIH were assessed using the Caries Assessment Spectrum and Treatment (CAST) and European Academy of Paediatric Dentistry (EAPD) criteria, respectively, by three examiners.

Caries risk assessment in schoolchildren--a form based on Cariogram software.

Unlabelled: Identifying caries risk factors is an important measure which contributes to best understanding of the cariogenic profile of the patient. The Cariogram software provides this analysis, and protocols simplifying the method were suggested.

Objectives: The aim of this study was to determine whether a newly developed Caries Risk Assessment (CRA) form based on the Cariogram software could classify schoolchildren according to their caries risk and to evaluate relationships between caries risk and the variables in the form.
