Previous studies have demonstrated that the presence of lactic acid bacteria (LAB), especially those classified into the genus Lactobacillus, is associated with the progression of dental caries in preschool children. Nevertheless, the kinds of species of LAB and the characteristics that are important for dental caries have been unclear. The aims of this study were: (1) to investigate the distri...

Aim: To estimate the prevalence and severity of dental caries in schoolchildren from the city of Florianópolis, SC, Brazil, in 2009 and to compare these results with data from previous studies carried out in the same institution since 1971. Methods: All 145 12and 13-year-old schoolchildren enrolled in a public school were eligible for the study. Dental caries was assessed with the DMFS/ DMFT in...

Th e infl uence of the diff erent extracts of propolis and chlorhexidine on mutans streptococci and the development of dental caries in rats was examined in this study. Specifi cally, the antimicrobial eff ects of propolis extracts (including ethanol, methanol, chloroform, hexane, propylene glycol, and ethyl acetate) on Streptococcus mutans UA159 and Streptococcus sobrinus 6715 were studied. Mi...

BACKGROUND Early childhood caries (ECC) is an aggressive condition that can affect teeth of young children. This study aimed to evaluate genotypic diversity and phenotypic traits of S. mutans isolated from dental biofilms of children with different caries status in comparison with caries free (CF) children. METHODS Streptococcus mutans strains were isolated from supragingival biofilm samples ...

PURPOSE The purpose of this investigation was to obtain information from practicing pediatric dentists about how they manage caries in children three years of age and younger and the problems they are encountering. METHODS A survey mailed to a randomly selected sample of 1,000 members of the American Academy of Pediatric Dentists (AAPD) in January of 1997 asked them to: identify the types and...

The aim of this study was to examine the colonization of Streptococcus mutans and Streptococcus sanguinis in the oral cavity and the association with severe early childhood caries (S-ECC). Saliva and plaque samples were collected from 14 S-ECC children and 8 caries-free (CF) children. All S-ECC children were S. mutans positive; 100% of CF children and 93% of S-ECC children were S. sanguinis pos...

The purpose of this study was to evaluate the 12-month clinical performance of glass ionomer restorations in teeth with MIH. First permanent molars affected by MIH (48) were restored with glass ionomer cement (GIC) and evaluated at baseline, at 6 and at 12 months, by assessing tooth enamel breakdown, GIC breakdown and caries lesion associations. The data were analyzed using the chi-square test ...

Dental caries declined in prevalence and severity among schoolchildren in the United States during the 1970s, although it still remains a problem in some areas. The decline could have started well before the 1970s, even though it was only recently identified. Caries should continue to decline as long as fluoride use remains around current levels. Use of fluoride toothpaste seems to be increasin...

Background: Hemophilic children must be thought of as special patients. Although there have been number of studies regarding with oral surgical, periodontal management of hemophilia there is paucity for the dental caries and its severity in hemophiliac children. The objective of this study is to assess prevalence of dental caries and treatment needs among hemophilic children attending Rajasthan...

Background: Dental caries appears long time ago and attracts great attention in the paleopathological research all over the world. However, few reports presented the status of dental caries in Chinese ancient people. Aim: To describe the prevalence of dental caries in 104 skulls about 2,200 years ago. Materials and Methods: This cross-sectional study was performed using 104 skulls which were ex...
