We develop the extended dynamical mean field theory (E-DMFT) with a view towards realistic applications. 1) We introduce an intuitive derivation of the E-DMFT formalism. By identifying the Hartree contributions before the EDMFT treatment, it allows to handle systems in symmetry breaking phases within a simple formalism. 2) We make a new implementation of E-DMFT through real Hubbard-Stratonovich...

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...

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 ...

The DMFT index, which represents caries experience as recommended by the World Health Organization (clinical examination without radiographs), was compared with a modified DMFT index with radiographs. The purpose was to evaluate how much the DMFT index underestimates the need for restorative care. A cohort of 376 young adults (eighteen to twenty years old) was examined from March 2003 to Decemb...

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...
