To persist in the oral cavity, bacteria must be able to tolerate rapid and substantial environmental fluctuations, particularly in pH and nutrient source and availability. Various species of Streptococcus, one of the most abundant genera in the mouth, are associated with oral health, as well as with dental caries. Cariogenic streptococci depend on a biofilm lifestyle for survival and persistenc...

The objective of this study was to determine the cariogenicity of 3 foods similar in texture, but varying in their sucrose concentration. The foods were evaluated in rats in which essential dietary nutrients were administered by gastric intubation. A modified Scow diet was used for the intubation procedure, administered twice daily over a 21-day experimental period. The test foods (Kellogg’s Co...

OBJECTIVES The Robert Wood Johnson Foundation (RWJF) has worked to ensure that all children have healthy weights. To promote this goal, the RWJF has supported the Healthy Futures: Engaging the Oral Health Community in Childhood Obesity Prevention National Conference, held on November 3-4, 2016, and the proceeding of this conference. The goals of the conference were to increase understanding of ...

Caries is an infectious disease affecting the organic and inorganic tissues of teeth. According to Global Burden Disease Study 2019, caries most frequently condition in about 3.5 billion people worldwide, who had oral diseases. If not prevented or treated a timely manner, it may significantly affect health have greater impact on economy individual as well country. The prevalence dental rise dev...

Background: Complementary infant formulas are the second most important sources of nutrition for neonates after breast milk. Considering the cariogenic potential of infant formulas, selection of these nutritive sources should be safe to reduce the risk of baby bottle syndrome in newborns. The present study aimed to estimate the plaque pH changes after rinsing with four customary used types of c...

Hypoxia is a typical pathological process that occurs when tissues are insufficiently supplied with oxygen or its utilization impaired. One of the most important pathogenetic factors in development tissue hypoxia disintegration structure mitochondrial membranes which under influence various etiological factors. In children who suffered antenatal period, frequency developmental delays significan...

AIM Polymethyl-methacrylate (PMMA) is commonly used primarily for baseplates of orthodontic appliances (BOA). The activities of cariogenic bacteria in biofilm on these surfaces may contribute to dental caries, gingival inflammation and periodontal disease. The PMMA incorporated with nanoparticles of silver (NanoAg-I-PMMA) and NanoAg in situ in PMMA (NanoAg-IS-PMMA) have been shown to control th...

We use three-dimensional holographic particle tracking to perform microrheological measurements of model gelled media, including the polysaccharide pellicle of dental biofilms created by the common cariogenic oral pathogen Streptococcus mutans. Nanometerresolution video-rate holographic tracking of embedded colloidal spheres provides accurate measurements of the gels’ complex viscoelastic modul...

OBJECTIVE The purpose of this study was to evaluate and to compare the cariogenic potential of different commonly consumed favored milk on caries development in rat's molar teeth. MATERIALS AND METHODS Sixty Sprague-Dawley rats infected with an active growing culture of Streptococcus mutans were offered chocolate favored milk, strawberry favored milk, banana favored milk, plain milk, sweetene...
