BACKGROUND Our study aimed to evaluate the effect of various risk indicators for dental caries on primary teeth of Nicaraguan children (from Leon, Nicaragua) ages 6 to 9, using the negative binomial regression model. MATERIAL/METHODS A cross-sectional study was carried out to collect clinical, demographic, socioeconomic, and behavioral data from 794 schoolchildren ages 6 to 9 years, randomly ...

AIM The aim of the Child Dental Health Survey in Lithgow was to establish the oral health status of primary schoolchildren to assist the local council in deciding whether to fluoridate the water and to provide a baseline for future monitoring of changes in caries rates. METHODS All six primary schools in Lithgow were invited to participate, and 653 children aged 6-12 years were clinically exa...

BACKGROUND Limited research has been undertaken in Australia to assess the dental status of pre-school Aboriginal children. This cross-sectional study records the number of decayed, missing and filled teeth (dmft) and surfaces (dmfs) of pre-school Aboriginal children living in different locations in New South Wales (NSW), Australia. METHODS A convenience sample of young children from seven Ab...

The objective of the present study was to determine caries prevalence and oral hygiene status among a group of Saudi cleft lip and palate (CLP) children. A total of 84 cleft children (45 males and 39 females) were examined for dental caries and oral hygiene status. The children were divided into two age groups; Group A with children age one to six years and Group B with children age seven to 14...

We investigate the dynamical mean-field theory (DMFT) from a quantum chemical perspective. Dynamical mean-field theory offers a formalism to extend quantum chemical methods for finite systems to infinite periodic problems within a local correlation approximation. In addition, quantum chemical techniques can be used to construct new ab initio Hamiltonians and impurity solvers for DMFT. Here, we ...

: BACKGROUND: Acidogenic, acid-tolerant bacteria induce dental caries and require D-alanyl glycerol lipoteichoic acid (D-alanyl LTA) on their cell surface. Because fluoride inhibits acid-mediated enamel demineralization, an elevated antibody response to D-alanyl LTA may indicate subjects with more acidogenic bacteria and, therefore, an association of DMFT with fluoride exposure and gingival hea...

This cross-sectional study aimed at evaluating the oral health conditions of building construction workers from a city in the mid-west region of São Paulo, Brazil. This study involved 219 male subjects, aged 17 to 72. The definition of a random sample utilized the functional number of each worker as a criterion to the raffle, which took into account all 450 subjects registered in the Working Ac...

BACKGROUND Dental caries is a lifetime disease, with highest priority risk group between 11-14 years of age group. Environmental factors such as culture, socioeconomic status, life style and dietary pattern can have a greater impact on caries-resistance or development. The present study was performed to evaluate the relationship between dental caries, oral hygiene status and risk factors among ...

OBJECTIVE There have been reports of a relationship between human histocompatibility antigen types and increased incidence of dental caries. The association between specific patterns of HLA genetic inheritance is not clear and not well studied. The aim of the study was to investigate the relationship between MHC alleles and DMFT index in 65 teenagers. MATERIALS AND METHODS Sixty-five teenager...

INTRODUCTION Surveys of dental health among Aboriginal children in Canada, using scales such as the Decayed, Missing, and Filled Teeth (DMFT) score, indicate that Aboriginal children have 2 to 3 times poorer oral health compared with other populations. A remote First Nations community approached requested assistance in addressing the health of their children. The objective was to work with the ...
