OBJECTIVE Dental caries is caused by prolonged episodes of low pH due to acid production by oral biofilms. Bacteria within such biofilms communicate via quorum sensing (QS). QS regulates several phenotypic biofilm parameters, such as biofilm formation and the production of virulence factors. In this study, we evaluated the effect of several QS modifiers on growth and the cariogenic potential of...

BACKGROUND Caries excavation is a noninvasive technique of caries removal with maximum preservation of healthy tooth structure. AIM To compare the efficacy of three different caries excavation techniques in reducing the count of cariogenic flora. MATERIALS AND METHODS Sixty healthy primary molars were selected from 26 healthy children with occlusal carious lesions without pulpal involvement...

When rats from dams fed a low-protein diet were injected with whole, killed Strepococcus mutans 6715 cells in the region of the submandibular gland, they developed serum and salivary agglutinins to this microorganism. Titers of agglutinins in malnourished rats were similar to those observed in rats from dams fed a nutritionally adequate diet that were locally injected with S. mutans. Furthermor...

BACKGROUND Recently, the dental literature has focused mainly on the microbial colonization of healthy full-term infants and their mothers or caretakers. However, oral microbial acquisition by premature infants has not been adequately investigated, and the correlation between pre-term birth and the presence of cariogenic and periodontal pathogens has not been determined. The aim of this study w...

Fluoride present in toothpaste at 1,100 µg/g is considered effective on caries control. However, under high cariogenic challenge due to increasing sugar exposure, higher fluoride concentration (5,000 µg/g) could be necessary to compensate the unbalance on caries process. This was tested in a pH-cycling regimen, which evaluated the effect of fluoride concentration relative to toothpaste on reduc...

Relevance. The high prevalence of tooth decay requires investigation its risk factors. aim was to study factors among six-year-old children according the level dental health (based on parents’ assessment). Materials and methods. research evaluated six-year-olds defining their oral health; surveyed 515 parents from 7 kindergartens in Arkhangelsk. Pearson chi-square test assessed differences freq...

objective: iron deficiency anemia is among the most common types of childhood anemia. according to the world health organization, approximately 5 billion people were suffering from iron deficiency anemia worldwide in 2001. aside from causing anemia, iron deficiency can negatively affect the physical and mental development of children and adolescents. several studies have discussed the consequen...
