OBJECTIVE To evaluate the role of socioeconomic variables and self-perceived oral health in the polarization of caries among adolescents in Santa Bárbara D'Oeste, Brazil. MATERIAL AND METHODS Cross-sectional study. Sampling was randomized and sample size was defined according to WHO criteria. Two hundred and seventy seven adolescents (15 to 18 year-old) were examined by five trained examiners...

BACKGROUND Data on epidemiology of dental caries of adults in rural India appear to be sparse. OBJECTIVE The purpose of the study was to assess the oral health status and dental treatment needs of a rural Indian population. MATERIALS AND METHODS The study population consisted of 189 volunteer subjects with a mean age of 34.9 ± 14.2 years and 54% males. Decayed, missing due to caries and fil...

We evaluated the DMFT (decayed, missing and filled teeth) index and the prevalence of candidiasis, linear gingival erythema, oral hairy leukoplakia, herpes simplex, aphthous ulcers, Kaposi's sarcoma and lymphoma, as well as the association with TCD4 count, viral load (VL) and antiretroviral therapy (ART) in 140 HIV-infected adult individuals. A standardized examination to determine the DMFT ind...

This study compared the caries index (dmft), presence of sucking habits and facial alterations in children attended by the preventive program for infants and children assisted by spontaneous demand, at the same age, at the public sector of Maringá, PR. A total of 100 children were evaluated (1-6 years), who were divided into 2 groups: GI - children attended by the infant program with educationa...

A cross-sectional study was performed with the aim to investigate the caries prevalence and associated factors in 6 to 15 year old school children living in a village outside Cluj-Napoca, Romania. All children were offered to be included and examined for dental caries according to World Health Organisation (WHO) criteria. Caries was scored at the tooth and surface levels D/d=decayed, M/m=missin...

Since 1995 the Department of Community Dentistry of the University of Pretoria has been involved in the rendering of mobile primary oral health care services to children in the Hammanskraal area of Gauteng, South Africa, as part of their students' community-based training. Mokonyama Primary School was identified as the first school where a primary oral health care service could be rendered. The...

Contrary to intuitive preconceptions, patients with Parkinson's disease (PD) have been reported to have less carious teeth. The present study was undertaken to seek responsible factors for this unexpected finding. The PD patients consisted of 31 consecutive university hospital outpatients who were 60 years old or over, and the controls of 104 comparable outpatients at a dental clinic. They were...

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)...

The main goal of this study was to evaluate the prevalence of caries in children that participate in a dental program attending mothers and children in Teresina, Piauí, Brazil. A selection was made of 343 children of both genders, from 3 to 6 years of age. The mothers answered questionnaires and children were examined at the Infant Dental Clinic of the Federal University of Piauí. The epidemiol...

We propose a combined density-functional-theory-dynamical-mean-field-theory (DFT + DMFT) approach for reliable inclusion of electron-electron correlation effects in nanosystems. Compared with the widely used DFT + U approach, this method has several advantages, the most important of which is that it takes into account dynamical correlation effects. The formalism is illustrated through different...
