BACKGROUND One of the causative factors in development of dental caries is microorganisms. Two species of Mutans streptococci including Streptococcus mutans and Streptococcus sobrinus are associated with dental caries in human beings. The aim of this study was to investigate the frequency of S. mutans and S. sobrinus in saliva of children with different caries activity and ability to form biofi...

Background: Caries experience, oral hygiene status, and salivary sCD14 level are three essential factors to analyse individual dental caries development risk. Therefore, regular effective instruction (OHI) is for prevention. Objective: This study aims the differences in levels before after OHI. Methods: An observational with intervention was conducted on 40 samples of each group taken an accide...

Environmental influences on the development and progression of dental caries are well known; however, there is little evidence of a genetic component imparting susceptibility to dental caries. The aim of this study was to investigate the relationship between a single nucleotide polymorphism in the vitamin D receptor TaqI locus and dental caries susceptibility in a Chinese population. This case-...

Streptococcus mutans (S. mutans) is the main etiological agent in dental caries. Its virulence factors are the proteins PAc and glucosyltransferase (GTF), which are related to its physiopathogenia and have been used in research for a dental caries vaccine. It was reported that using experimental animal models, GTF-I(1301-1322) synthetic peptide from the GLU region of the GTFs has Tepitopes, ind...

OBJECTIVE To determine the prevalence and severity of dental caries and to assess treatment needs among schoolchildren aged 6 and 12 in Blumenau, Brazil, and to compare the results found for private and public schools. METHODS A schoolchildren population of Blumenau, SC, Brazil, was studied. A random sample of 1,473 schoolchildren from Blumenau, Brazil, was obtained. Four strata were studied:...

PURPOSE This study assessed the association of caries, plaque accumulation, gingival health, and antiretroviral therapy (AT) with oral lesion prevalence in human immunodeficiency virus (HIV)-infected Romanian children. METHODS A convenience sample of HIV-infected children who received dental care in 2 hospitals were evaluated for oral lesions, caries (dfs+DFS/total teeth present), plaque (PI,...
