Introduction 1 INTRODUCTION From a microscopic ab-initio point of view, a solid material is an interacting many-particle system involving both ions and electrons. However, according to the Born-Oppenheimer approximation (Born and Oppenheimer, 1927), the ions and electrons can be treated separately. Indeed, many properties of solids can be well described by the electronic degree of freedom, whil...

Objectives: The purpose of this cross-sectional study was to determine whether there is a relationship between dmft (decayed, missing and filled primary teeth) index and Body Mass Index for age (BMI-%) in 6-year-old children. Study design: A census sample of 2197 healthy children(51.1% boys/48.9% girls) aged 72-84 months with a mean age of 77.52 ± 3.49 months was included. The dmft index and BM...

PURPOSE The aim of this study was to evaluate whether poor oral hygiene is associated with carotid and popliteal arterial intima-media thickness, which is one of the predictors of future progression of sub-clinical atherosclerosis, and highsensitivity C-reactive protein (hsCRP) and fibrinogen levels. METHODS A specialised dentist checked the patients and selected 550 patients during periodont...

OBJECTIVE The purpose of this study was to evaluate caries and dental fluorosis among Mexican preschoolers and school-aged children in a non-endemic zone for fluorosis and to measure its biological indicators. METHODS DMFT, DMFS, dmft, dmfs, and CDI indexes were applied. Fluoride urinary excretion and fluoride concentrations in home water, table salt, bottled water, bottled drinks, and toothp...

AIM The relationship between bone mineral density (BMD), age and dental caries has been studied. Quantitative ultrasonography (QUS) is an economic, non invasive, and reproducible method for measuring both bone mineral density and bone elasticity in growing subjects in large populations. METHODS This study evaluated the relationship between BMD and prevalence of dental caries (Decayed Missing ...

Objective To determine the dental caries experience and treatment needs among 5-year-olds in Albania. Research Design This cross sectional study was conducted in 2015 by using a cluster sampling technique. The dmft was used to assess dental caries experience and caries prevalence as percentages of children with dmf⟩0. Caries treatment needs were assessed with dt/dmft x 100, missing teeth with...

OBJECTIVE To analyze whether two simplified indices, "DMF in 6 Teeth"(DMF6T) and "DMF in two quadrants" (DMF2Q), could be indicated for epidemiological surveys of oral health according to dental caries distribution. METHODS The sample came from epidemiological data in 29 municipalities. A total of 2,378 examinations were done on 12-year-old schoolchildren. The mean DMFT from each locality was...

The electronic properties of paramagnetic V2O3 are investigated by the computational scheme LDA+DMFT(QMC). This approach merges the local density approximation (LDA) with dynamical mean-field theory (DMFT) and uses quantum Monte Carlo simulations (QMC) to solve the effective Anderson impurity model of DMFT. Starting with the crystal structure of metallic V2O3 and insulating (V0.962Cr0.038)2O3 w...
