OBJECTIVES To determine the prevalence of dental caries, and associated social risk factors among preschool children in Riyadh, Saudi Arabia. METHODS The study consisted of a random sample of 3 to 5 years- old preschool children who were examined in Riyadh, Saudi Arabia; 388 children (184 boys and 204 girls) were examined from 10 different preschools. Each surface of their teeth was examined ...

A deep learning approach for the efficient electromagnetic analysis of an on-chip inductor with dummy metal fillings (DMFs) is proposed. By comparing different activation functions and loss functions, a neural network DMF modeling built using smooth maximum unit function log-cosh function. The parasitic capacitive effect DMFs quickly accurately extracted though this model, effective permittivit...

AIMS The aim of this study was to determine the prevalence, severity, and pattern of dental caries in 6 to 7-year-old children in military primary schools in Jeddah city, Saudi Arabia. METHODS AND MATERIALS A random sample of 300 children (6 to 7-year-olds) was drawn from six schools of military dependents. Clinical examinations were carried out under standardized conditions by two trained an...

BACKGROUND Asthma has been associated with a great number of negative health outcomes. This study was undertaken to detect the association between asthma and dental caries in the primary dentition. METHODS Data were obtained from a cohort of 1160 Mexican children aged 4-5 years. We used the questionnaire of the International Study of Asthma and Allergies Diseases in Childhood. Asthma was clas...

background and aims. dental caries still remains a major problem in the field of oral and dental health and its prevention is more important than its treatment. fluoride plays a significant role in prevention of caries, and improving oral and dental health. one of the common ways of fluoride use is the use of a fluoride-containing mouthwash, the most important of which in use is 0.2% sodium flu...

OBJECTIVES To assess oral health outcomes of a school-based oral health education (OHE) programme on children, mothers and schoolteachers in China, and to evaluate the methods applied and materials used. DESIGN The WHO Health Promoting Schools Project applied to primary schoolchildren in 3 experimental and 3 control schools in Hongshan District, Wuhan City, Central China, with a 3-year follow...

The aim of the study was to investigate some aspects of the oral health of male Saudi military inductees with special reference to soft-drink consumption, dental erosion, caries and fluorosis prevalences; a second aim of the study was to develop a system for assessing dental erosion. The material comprised a random selection of 95 individuals with a mean age of 20.9 years (range, 19-25 years). ...

AIM The aim of this study is to assess the effects of fluoride varnishes on enamel caries lesions on permanent dentition. MATERIALS AND METHODS 92 children from primary school (Vasil Shanto, Tirana, Albania) aged 11-12 years were divided into varnish (experimental) and control group. The experiment group received the first fluoride varnish application (Fluoridin, Voco) at baseline, the second...

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...
