BACKGROUND Streptococcus mutans (S. mutans) is the primary etiological agent of dental caries. Sortase is a transpeptidase that anchors several surface proteins to the S. mutans cell wall and has been shown to play a major role in cariogenicity. The purpose of this study was to explore the genetic polymorphisms of the sortase gene (srtA) and the social-behavioural factors associated with dental...

OBJECTIVE The aim of this study was to investigate whether Quantitative Light-induced Fluorescence-Digital (QLF-D) could monitor the degree of maturation of dental microcosm biofilms by observing the red fluorescence emitted from the biofilms. METHODS Dental microcosm the biofilms were grown on bovine enamel discs. They were initiated from human saliva, and then grown in 0.5% sucrose growth m...

background: the aim of this study was to study the knowledge and attitude of the pediatricians and family physicians on the dental counterpart, i.e. pediatric dentistry and the objective of this study were to determine what can improve the knowledge and attitude on pediatric dentistry and suggest certain methodologies to more participation of physicians in improving oral health. materials and m...

The aim of the current study was to investigate the anticariogenic potential of the (sub)fractions obtained from the edible mushroom shiitake (Lentinula edodes) in in vitro caries model. We used a modified constant depth film fermentor (CDFF) with pooled saliva as the inoculum and bovine dentin as a substratum. The test compounds were low molecular weight fraction (MLMW) of the shiitake extract...

Introduction. Promoting a commitment to dental caries prevention in young children plays vital role establishing healthy lifestyle habits that ward off diseases. The initial visit is as cornerstone for fostering parental motivation preventing issues and providing optimal conditions the development of eating habits, oral care practices, use fluoride toothpaste. foundation knowledge, skills laid ...

The common oral bacterium Streptococcus sanguis can degrade arginine via the arginine deiminase (AD) system. The three enzymes of this system, AD, ornithine carbamyltransferase (OTC), and carbamate kinase (CK), catalyze the breakdown of arginine to ornithine, CO2, and two molecules of ammonia, with the production of ATP from ADP. The genes of the AD system, which are subject to complex regulati...

Twelve presweetened breakfast cereals were evaluated for cariogenic potential by in vitro methods. The parameters evaluated were the levels of acid produced by a cariogenic strain of Streptococcus mutans as influenced by each cereal, the percentage of sugar content, and the salivary retention time of glucose after ingestion of each cereal with or witho~¢t milk. Cariogenicity was found to be rel...

Nitrates have been used as an antimicrobial agent in foods for hundreds of years. As a result there is extensive literature on their mode of activity in the food sciences and other such diverse fields as gastroenterology, the pulmonary sciences, and cancer research but minimal research exists in the dental sciences. This manuscript will describe how nitrate present in green leafy vegetables is ...

Caries is a unique multifactorial infectious disease. Our understanding of etiological factors, the progress of the disease, and the effectiveness of prophylactic procedures have led us to believe that we understand the disease. However, we still have too few answers to many questions: "Why can we not predict who will get the disease?" "Why do we not become immunized?" "How much saliva is enoug...

Background information was compared for children with carious primary h~cisors versus caries-free children in different geographic and practice locations: private practices in Baton Rouge, Louisiana, and Akron, Ohio, and university-affiliated clinics in Cleveland, Ohio, and Morgantown, West Virginia. In several respects nursing caries cuts across geographic boundaries and practice settings. Dat...
