BACKGROUND/AIMS Severe early childhood caries is a microbial infection that severely compromises the dentition of young children. The aim of this study was to characterize the microbiota of severe early childhood caries. METHODS Dental plaque samples from 2- to 6-year-old children were analyzed using 16S rRNA gene cloning and sequencing, and by specific PCR amplification for Streptococcus mut...
In Germany, caries of young people has been declining since the late 1980s, while the prevalence of early childhood caries has remained steady. Data from a number of regional studies suggest a current prevalence between 10% and 15%. However, there is a dearth of longitudinal observational study data on the risk of caries in the permanent teeth of persons who as children had to undergo comprehen...
background: knowledge of existing situation in each region plays great role in order to prevent oral and dental diseases in people. meanwhile, dmft index is one of the best epidemiological indices in dentistry representing oral hygiene situation in society. so, this study was conducted in order to evaluate dmft index in 12- years-old students of zarand city at 2011. methods: this descriptive st...
Varsio S. Caries-preventive treatment approaches for child and youth at two extremes of dental health in Helsinki, Finland. Department of Oral Public Health, University of Helsinki, Finland, 1999. 65 pp. ISBN 952-91-1150-9. This study determined the prevalence and distribution of dental caries among young populations during the last two decades in Helsinki, Finland, and evaluated dentists’ cari...
This study compared salivary bacterial profiles in two groups having a 10-fold difference in levels of caries experience, as it was hypothesized that the composition of the salivary microbiota might associate with the levels of caries experience. Bacterial profiles in stimulated saliva samples from 85 individuals with low levels of caries experience (healthy group) and 79 individuals with high ...
OBJECTIVE The aim of this study was to investigate the correlation between the demineralization depth measured by dental computed tomography (CT) and the measured value from a non-destructive dental caries diagnosis with a laser. METHODS Optimal cut-off points were obtained for enamel and dentin caries, from the measured levels from a dental caries diagnosis with a laser, to investigate the c...
Background: Varnish, when brushed onto the teeth, provides a highly concentrated dose of fluoride and maintains prolonged contact with enamel to inhibit caries. Objective: Our study aims to evaluate the effect of mineralizing fluorine varnish on the progression of initial caries of enamel in temporary dentition by laser fluorescence. Material and Methods: Object of observation. 1 group 100 chil...
The rate of dental caries and periodontal diseases in the world is still high, regardless of progress in the oral and dental hygiene. The natural toothbrush or chewing stick called “Miswak” has been used since ancient history. In this research the efficacy of Miswak in preventing dental caries was investigated and compared with the efficacy of toothbrush and toothpaste. The analytical and clini...
Dental caries in very young children may be severe, result in serious infection, and require general anesthesia for treatment. Dental caries results from a shift within the biofilm community specific to the tooth surface, and acidogenic species are responsible for caries. Streptococcus mutans, the most common acid producer in caries, is not always present and occurs as part of a complex microbi...
Peptide constructs from the catalytic (CAT) and glucan-binding (GLU) regions of the mutans streptococcal glucosyltransferase enzymes (GTF) can provide immunity to dental caries infection. A strategy of coimmunization was tested to determine whether protection could be enhanced. Rats were immunized with one of the previously described peptide constructs from the CAT or GLU region of the GTF of m...
