BACKGROUND Bacteria affect oral health, but few studies have systematically examined the role of bacterial communities in oral diseases. We examined this relationship in a large population-based Chinese cancer screening cohort. METHODS Human Oral Microbe Identification Microarrays were used to test for the presence of 272 human oral bacterial species (97 genera) in upper digestive tract (UDT)...

BACKGROUND Dental caries develops as a result of the metabolism of carbohydrates by cariogenic bacteria present in a complex biofilm. The present study aimed to examine if bacteria in pooled supragingival plaque samples quantified using a "checkerboard DNA-DNA hybridization" based panel of caries-related bacteria, could reflect the caries experience in a manner similar to saliva samples analyse...

Previous studies have indicated that there may be a relationship between the salivary fluoride concentrations and dental caries while the emphasis was on dental caries in permanent teeth. The aim of this study was to assess the prevalence of dental caries and its predictors in 3-6 year-old children in Tehran, Iran. The other objective of this investigation was to clarify a relationship between ...

In this study we describe the dental status and oral hygiene practices in institutionalized older people and identify factors associated with poor dental status. A cross-sectional study was performed in a nursing home in Fortaleza, the capital of Ceará State (northeast Brazil). The number of decayed, missing, and filled teeth (DMFT) was assessed in the residents of the nursing home (n = 167; me...

BACKGROUND The aim of this study was to analyse the prevalence and severity of dental caries among Korean children aged 8 and 12 years over a period of 12 years by determining the number of decayed, missing, and filled teeth (DMFT) and the Significant Caries index (SiC index). METHODS Stratified cluster-sampled data from the National Oral Health Survey conducted from 2000 to 2012 were analyse...

conclusions the dental health status of hiv-positive patients in this region was almost inappropriate. most social, behavioral, and medical factors had no influence on dental health; only a correlation between dental health, age, and duration of hiv involvement was observed. results the mean value of dmft index was 11.87 ± 8.08, where the mean values of decayed and missing teeth were 8.42 ± 5.4...

OBJECTIVE The purpose of this study was to assess the prevalence of dental caries, developmental defects of enamel, and related factors in children with clefts. DESIGN This cross-sectional prevalence study used standard dental indices for assessment. SETTING Children underwent a dental examination under standard conditions of seating and lighting in the outpatient department of a dental hos...
