Dental decay is one of the most prevalent chronic diseases worldwide. A variety of factors, including microbial, genetic, immunological, behavioral and environmental, interact to contribute to dental caries onset and development. Previous studies focused on the microbial basis for dental caries have identified species associated with both dental health and disease. The purpose of the current st...

In 2002 a dental survey amongst 6- and 12-year-old schoolchildren (n = 832) in The Hague was carried out. The caries findings were compared with findings from earlier studies in The Hague. Caries prevalence (% of caries-free children) and caries experience (mean dmfs scores) among 6-year-old children had not changed significantly in the period 1996-2002. However, a significant increase of carie...

Aim. The aim of the present paper was to evaluate the genotypic diversity of S. mutans in caries-free and caries-active preschool children in Brazil. Design. Twenty-eight preschool children were examined regarding caries experience by the dmft index. DNA from 280 isolates of S. mutans was extracted. S. mutans evaluated using to the PCR method, with primers for the glucosyltransferase gene. The ...

Clinical care pathways have placed renewed emphasis on caries risk assessment and the ability to predict and prevent further disease. With diet considered a key factor in the development of caries, the level of caries risk posed by dietary habits, such as the frequency of intake and timing of free sugars is questioned. OBJECTIVE To identify reliable and simple dietary risk factors for caries ...

This study was evaluated the clonal diversity of Streptococcus mutans in caries-free and caries-active subjects using MLEE. Strains from caries-free subjects were grouped in a single taxon. Unrooted dendrogram showed that different strains clustered in four different clades, also showed that more than one clonal type can be found in a same individual.

background:   to find out if there is an association between levels of salivary mutans streptococci (ms)   materials and methods:   t -test were used to find differences between groups. p   results:   p   p   p   conclusion:   present study showed a strong association between maternal and child salivary   ms levels indicating that mother’s ms count could be an important risk indicator for ecc d...

OBJECTIVE To evaluate the genotypic diversity and some virulence traits of Streptococcus sobrinus (S. sobrinus) isolated from caries-free children and children suffering severe early childhood caries (SECC). METHODS S. sobrinus isolated from stimulated whole saliva samples of 91 caries-free children and 87 SECC children were subcultured, identified by polymerase chain reaction and genotyped b...

Background and objectives: The purpose of this study was to evaluate the relationship between the physicochemical properties of saliva such as flow rate, pH, buffering capacity, calcium level, total protein and total antioxidant levels in caries free and caries active children. Materials and methods: The present study included one hundred and twenty healthy children who were divided into two gr...

BACKGROUND Candida albicans may have cariogenic potential but its role in caries etiology has not been established. The aim of this study was to determine candida albicans in supragingival dental plaque and infected dentine of cervical and proximal in early childhood caries (ECC). METHODS This cross-sectional study was carried out on 6o children aged 2-5 years, which were divided into 3 group...
