Longitudinal microbiological examinations have been made of dental plaque from a site approximal to the upper central incisors of 10 8-year-old children living in an area with water fluoridation. Differential counts of viable bacteria, made using a selective medium containing various levels of fluoride (0 to 100 mug/ml) at pH levels of 7.0 to 5.5, demonstrated an effect of both pH and fluoride ...

Dental caries remains a significant public health problem and is considered pandemic worldwide. The prediction of dental caries based on profiling of microbial species involved in disease and equally important, the identification of species conferring dental health has proven more difficult than anticipated due to high interpersonal and geographical variability of dental plaque microbiota. We h...

Oral diseases, including dental caries, periodontal disease, and tooth loss, affect the majority of the population and can affect a person's overall health. Raisins contain polyphenols, flavonoids, and high levels of iron that may benefit human health. However, their oral health benefits are less well understood. We hypothesized that raisins contain antimicrobial phytochemicals capable of suppr...

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...

OBJECTIVE This study evaluated whether Quantitative Light-induced Fluorescence-Digital (QLF-D) can detect the levels of cariogenicity of dental microcosm biofilms by assessing the red fluorescence intensity. METHODS Dental microcosm biofilms were initiated from human saliva on bovine enamel discs. Biofilms with various levels of cariogenicity were then grown in artificial saliva supplemented ...

In Romania, bronchial asthma represents a major public health problem. SCOPE: The study discusses the effects of bacterial plaque control upon the quality of respiration in a group of ashtmatic children previously subjected to professional dental scaling and brushing, comparatively with a similar group, whose habits of oral hygiene had not been influenced. In both groups, the indices of bacteri...

Dental caries and periodontal diseases, the two arch criminals of oral cavity, are essentially caused by the micro-organisms present in dental plaque [1]. In India, nearly 60-65% of the child population is affected by dental caries and 10% has periodontitis [2,3]. Dental plaque plays an important role in the development of dental caries and periodontal disease, which results in both dysfunction...

In previous studies, the abundance and diversity of methanogenic archaea in the dental microbiota have been analysed by the detection of specific DNA sequences by PCR-based investigations and metagenomic studies. Few data issued regarding methanogens actually living in dental plaque. We collected dental plaque specimens in 15 control individuals and 65 periodontitis patients. Dental plaque spec...
