OBJECTIVE The present study evaluated the association between lactotransferrin (LTF) gene polymorphism (exon 2, A/G, Lys/Arg) and dental caries. MATERIAL AND METHODS A convenience sample of 110 individuals, 12 years old, was divided into: group 1, 48 individuals without caries experience (DMFT=0), and group 2, 62 subjects with caries experience (DMFT>or=1). DNA was obtained from a mouthwash w...
We derive a dynamical mean-field theory for mixtures of interacting bosons and fermions on a lattice (BFDMFT). The BF-DMFT is a comprehensive, thermodynamically consistent framework for the theoretical investigation of Bose-Fermi mixtures and is applicable for arbitrary values of the coupling parameters and temperatures. It becomes exact in the limit of high spatial dimensions d or coordination...
We present a fully self-consistent combined GW and dynamical mean field (DMFT) study of the extended two-dimensional Hubbard model. The inclusion of the local dynamical vertex stemming from the DMFT self-energy and polarization is shown to cure the known problems of self-consistent GW. We calculate momentum-resolved spectral functions, two-particle polarizations, and electron-loss spectra, as w...
OBJECTIVE To explore socioeconomic inequalities in dental caries among 5-year-olds in four Chinese provinces. METHODS This study used data from 1,732 children living in Guangxi, Hubei, Jilin and Shanxi who participated in the Third National Oral Health Survey in 2005. Questionnaires were completed by parents to collect information on family socioeconomic position (parental education and house...
BACKGROUND There have been inconsistent conclusions regarding salivary abnormalities and their effect on oral health of Juvenile Idiopathic Arthritis (JIA) patients. The purpose of the study was to evaluate the flow rate and selected biochemical parameters of unstimulated whole saliva in correlation to oral health in JIA children. METHODS Thirty-four JIA patients and 34 age- and sex-matched c...
Background:DMFT index is the most common caries detecting index worldwide. The aim of present study was to determine DMFT as well as the prevalence of highest caries rate or Significant Caries Index (SiC), among 15 years of age female students in the city of Rasht, Iran. Materials and methods: In this descriptive cross-sectional study, 228 female students were selected using stratified multi-st...
زمینه: پوسیدگی دندان از رایجترین بیماریهای مزمن کودکان در سراسر جهان است. هدف: مطالعه بهمنظور تعیین وضعیت سلامت دهان- دندان کودکان استان قزوین و نقش عوامل جمعیتی و رفتارهای بهداشتی مرتبط با آن انجام شد. مواد و روشها: این مطالعه مقطعی در سال 1392 بر روی 373 کودک در گروههای سنی 5 تا 6 و 12ساله استان قزوین انجام شد که با روش نمونهگیری خوشهای انتخاب شدند. اطلاعات جمعیتی، تعداد دفعههای مسواک...
The aim of the study was to assess the caries prevalence and oral hygiene in groups of adolescents living in different Hungarian localities and to establish correlations with socio-economic factors. Examinations of caries and oral hygiene were performed in 586 14-16 year old children. The percentage of caries free children was 5.1%, the DMFT and DMFS values were 6.97±4.67 and 9.95±7.94 respecti...
The objective of the study was to develop regression models to describe the epidemiological profile of dental caries in 12-year-old children in an area of low prevalence of caries. Two distinct random probabilistic samples of schoolchildren (n=1,763) attending public and private schools in Piracicaba, Southeastern Brazil, were studied. Regression models were estimated as a function of the most ...
