The central idea of the Brazilian health system is to prevent the establishment of disease or detect it as early as possible. Prevention and treatment of dental caries are related to behavioral factors, including dietary and oral hygiene habits, which are related to many chronic diseases. Dental health promotion therefore should be fully integrated into broadly based health-promoting strategies...

One of the primary causes for the failure of glass ionomer cement (GIC) is secondary caries. To enhance the anti-microbial performance of GIC without affecting its mechanical properties, chlorhexidine (CHX) was encapsulated in expanded-pore mesoporous silica nanoparticles (pMSN) to synthesize CHX@pMSN. CHX@pMSN was added at three mass fractions (1%, 5%, and 10% (w/w)) to GIC powder as the exper...

Caries is an infectious, chronic and cumulative disease. It seriously affects quality of life and creates considerable expense for individuals and communities. The disease can be managed by acting on biofilm formation and maturation, by modifying the kinetics of apatite solution or with a combination of the two processes. This can be achieved by mechanical and chemical control of plaque, approp...

The mechanical properties and anti-caries effect of a novel anti-caries adhesive containing poly (amidoamine) dendrimer (PAMAM) and dimethylaminododecyl methacrylate (DMADDM) were investigated for the first time. Microtensile bond strength and surface charge density were measured for the novel anti-caries adhesives. Streptococcus mutans, Streptococcus sanguinis, and Streptococcus gordonii were ...

Background: Saliva is one of the most important factor in regulating oral health, with flow rate and composition changing throughout development and during disease. Saliva can affect incidence of dental caries in four general ways, firstly as a mechanical cleansing, secondly by reducing enamel solubility by means of calcium, phosphate and fluoride, thirdly by buffering and neutralizing the acid...

This study was carried out to evaluate in situ the influence of microleakage, surface roughness and biofilm control on caries formation around composite resin restorations. During 28 days, 12 volunteers wore palatal devices containing bovine enamel slabs restored with composite resin. Restorations were made without leakage, when the adhesive system was applied, or with leakage, when adhesive sy...

BACKGROUND The purpose of this study is to determine the type and frequency of pathological conditions around third molar teeth among randomly selected patient's records in Oral and Maxillofacial Surgery, College of Dentistry, King Saud University, Riyadh. MATERIALS AND METHODS Totally, 281 patient panoramic radiographs were selected with detectable pathology among 570 files of patients seen ...

It is generally accepted that three conditions are essential in the oral cavity for dental caries to occur: a suitable microbe, a substrate for the microbe, and a susceptible tooth. Susceptibility or resistance to dental caries is usually thought of in terms of structure, which is determined, for the most part, during calcification. However, it is also plausible that susceptibility to dental ca...

Secondary caries has been reported as the main reason for restoration replacement. The aim of this in vitro study was to evaluate the performance of different methods--visual inspection, laser fluorescence (DIAGNOdent), radiography and tactile examination--for secondary caries detection in primary molars restored with amalgam. Fifty-four primary molars were photographed and 73 suspect sites adj...
