BACKGROUND The aim of this study is to examine the association between parental socioeconomic status (SES) and the experience as well as treatment of dental caries among children aged 9 to 18 years. METHODS Data from 1253 children aged 9-18 years from the Korean National Health and Nutrition Examination Survey (2012-2013) were analyzed. Parental socioeconomic status was measured using househo...

The goal of the proposed project is to develop an algorithm for predicting the molecular function of a protein from a structural model of its active sites. Given the 3D atomic coordinates for a novel protein and the location of a ligand binding site, we build a model of the site cavity, match it against a database of active sites models having known molecular functions, and make predictions bas...

Saliva adhesion of bacteria is a key event in oral biofilm formation. Here, we used partial least-squares (PLS) analysis to correlate adhesion of cariogenic (Streptococcus mutans Ingbritt) and commensal (Actinomyces naeslundii LY7) model bacteria, and their agglutinin and acidic proline-rich protein ligands, respectively, with high and low caries experiences in 38 children reflecting today's sk...

This work correlated the presence of oral streptococci in dental biofilm with clinical indexes of caries and oral hygiene in caries-active and caries-free children. S. mutans and/or S. sobrinus in the dental biofilm does not indicate a direct risk for developing dental caries.

Manifestations and treatment of caries are strongly dependent on caries risk and the severity of the attacking factors which determine the degree of caries activity. Caries activity in turn will be modified and can be minimized by effective preventive measures. Exemplary cases and events will be discussed to illustrate what has happened since the establishment of ORCA 50 years ago.

PURPOSE This study aimed to investigate the effect of changing the kilovoltage peak (kVp) on the radiographic assessment of dental caries. MATERIALS AND METHODS Seventy-five extracted posterior teeth with proximal caries or apparently sound proximal surfaces were radiographed with conventional E-speed films and a photostimulable phosphor system using 60 kVp and 70 kVp for the caries assessmen...

Dental caries, a chronic infectious disease, affects more than 90 percent of all adults in the United States and over 80 percent of all adults in Korea. Historically, caries have been prevalent since the time of pre-Neolithic humans (10,000 BC) with a reported prevalence between 1.4% and 12.1% carious teeth, but it was not until the fourteenth and fifteenth century when a sharp increase in cari...

Early childhood caries affects 28% of children aged 2-6 in the US and is not decreasing. There is a well-recognized need to identify susceptible children at birth. Caries-free adults neutralize bacterial acids in dental biofilms better than adults with severe caries. Saliva contains acidic and basic proline-rich proteins (PRPs) which attach to oral streptococci. The PRPs are encoded within a sm...
