We present a joint implementation of dynamical-mean-field theory (DMFT) with the pseudopotential plane-wave approach, via Wannier functions, for the determination of the electronic properties of strongly correlated materials. The scheme uses, as input for the DMFT calculations, a tight-binding Hamiltonian obtained from the planewave calculations by projecting onto atomic-centered symmetry-const...

The aim of this study was to determine the caries prevalence in urban and suburban Albanian schools. A large sample (n= 2617) of subjects, aged 7-15, was examined by a clinical observation without radiograms. The sample comprised 1257 males and 1360 females. For each subject an anamnestic questionnaire about feeding, fluoride, dentist attendance and familiar informations was obtained. Gender an...

Objective: The study aimed to establish the mean DMFT of adults over the age of 20 years in Bulgaria. We also aimed to determine any association between demographic factors, such as age, gender, general health status etc, and dental caries. Material and Methods: The study was conducted from 2006 to 2009. Data was collected from a randomly chosen representative sample of 1741 adults aged over 20...

Dental decay is a disease that is greatly affected by environmental components, but recently there have been an increasing number of documents supporting a genetic factor in the development of caries. The purpose of this study was to examine the association between dental caries and single-nucleotide polymorphisms in the AMELX gene. This research was carried out on 360 individuals of both sexes...

BACKGROUND To assess the impact of children's dental health status (DHS) on their oral health-related quality of life (OHRQoL). METHODS Participants were 11- and 12-year-old children attending public schools in the Kuwait Capital Region. Children's DHS was evaluated by clinical examinations and presented using decayed, missed, filled teeth/surface (DMFT/dmft, DMFS/dmfs); restorative (RI), pla...

Seven hundred and twenty school children of primary school grades 5 and 6 in Hadba Sargia area in Tripoli were examined for dental caries. The mean DMFT index for the whole sample of children was 1.58. The DT component comprised 1.34 and MT component 0.21 of DMFT score, which made 42.22% and 13.33% of total children sample, respectively. The amount FT component was 0.03 (1.39%) of all children ...

BACKGROUND Dental caries is a lifetime disease and its sequelae have been found to constitute health problems of immense proportion in children. Environmental factors such as culture, socioeconomic status, lifestyle and dietary pattern can have a great impact on cariesresistance or caries-development in a child. OBJECTIVE The present study was conducted to evaluate the relationship between de...

AIM The aim of this study is to determine the dental caries and oral health behavior status of urban adolescents in Iran. Also it assesses the influence of the socioeconomic background on their oral health outcomes. METHODS A cross-sectional study was conducted in the students living in the city of Isfahan, Iran. 597 adolescents by 13 to 17 years old participated in the study. The asset-based...
