We address the nature of the Mott transition in the Hubbard model at half-filling using cluster dynamical mean field theory (DMFT). We compare cluster-DMFT results with those of single-site DMFT. We show that inclusion of the short-range correlations on top of the on-site correlations does not change the order of the transition between the paramagnetic metal and the paramagnetic Mott insulator,...

OBJECTIVE To validate the Community Oral Health Indicator-COHI by non-dental personnel. METHODS Risk assessment is an essential component in the decision-making process. Therefore, the COHI, an instrument to evaluate population oral health situation in a simple manner, was created. Community Health Agents (CHA) were trained to use the COHI (variables as number of teeth, presence of cavities, ...

Aims and Objectives Self-rated oral health is the key element that has a greater effect on quality of life and found to be authentic and logical to consider this as an indicator for overall oral health status. The aim was to investigate and identify the impact of various social and clinical factors on the perceived self-rated oral health status (PSR-OHS). Materials and Methods A self-administ...

OBJECTIVE To describe the status of dental caries in a sample of Iranian adolescents aged 14 to 18 years in Qazvin, and to identify caries-related factors affecting this group. STUDY DESIGN Qazvin was divided into three zones according to socio-economic status. The sampling procedure used was a stratified cluster sampling technique; incorporating 3 stratified zones, for each of which a cluste...

Objectives: Due to the important influence of glycemic control on oral health, this study aimed compare gingival index and decayed, missing, filled teeth (DMFT) in participants with type 2 diabetes mellitus receiving insulin metformin. Materials Methods: In cross-sectional study, 130 treated metformin were studied two groups based treatment. The information for DMFT indices obtained using exami...

BACKGROUND The objectives of this study were to assess the association between children and parents' knowledge of caries preventive practices, the parents' caries preventive oral health behaviours and children's caries preventive oral health behaviour and caries experience. METHOD Three hundred and twenty four participants aged 8-12 years, 308 fathers and 318 mothers were recruited through a ...

In this study, we investigated the oral status of children suffering from end-stage renal disease (ESRD) with the aim of determining the causes of low caries prevalence in this population (using the CRT bacteria and buffer test), and compared results with a control group (n=38). In the study group, there were 38 children (aged 4-17 years) who were being treated in pediatric nephrology units at ...

BACKGROUND Limited information on oral health status for young adults aged 18 year-olds is known, and no available data exists in Hong Kong. The aims of this study were to investigate the oral health status and its risk indicators among young adults in Hong Kong using negative binomial regression. METHODS A survey was conducted in a representative sample of Hong Kong young adults aged 18 year...

Objective: The purpose of this study was to investigate the caries experience in 6 -12‐yearold schoolchildren in Kashmir Division of Jammu and Kashmir state, India. Material & methods: This study was carried out in Budgam District of Kashmir Division of Jammu and Kashmir State, India. A cluster sampling was done to collect the sample. Schools accessible and situated in the district were selecte...
