statement of problem: fixed orthodontic appliances can interfere with removing bacterial plaques from dental surfaces which can ultimately lead to white spot formation. purpose: the aim of this study was to evaluate the quantity of white spots and areas of decalcification following fixed orthodontic treatment. materials and methods: a total of 100 patients undergoing or scheduled for fixed orth...

Introduction: Nowadays, thanks to improvements in fruit yoghurt tastes, more tendencies are seen in their consumption especially among children. Therefore, their cariogenicity evaluation as healthy snacks is important. The goal of this study was the assessment of the consumption effect of two kinds of Iranian fruit (apple) and plain yoghurts on dental plaque PH. Methods: In this experimental st...

Summary Background & aims Oral nutritional supplements (ONS) administered to malnourished elders and other patients contain high-levels of carbohydrates that could be a potential risk factor for dental caries. This study aimed evaluate the cariogenic potentials ONS using intraoral plaque telemetry. Methods Ten were tested on five healthy volunteers (mean age: 76.8 ± 9.15 years). Participants re...

The purpose of this study was to investigate the association between the probability of having high DMFT scores and reported consumption of eight food groups. The sample included Americans (aged from 9 to 29 years) examined during the first National Health and Nutrition Examination Survey conducted between 1971 and 1974. Analysis was restricted to comparing those individuals having DMFT scores ...

BACKGROUND Identifying the microbial species in caries lesions is instrumental to determine the etiology of dental caries. However, a significant proportion of bacteria in carious lesions have not been cultured, and the use of molecular methods has been limited to DNA-based approaches, which detect both active and inactive or dead microorganisms. OBJECTIVE To identify the RNA-based, metabolic...

Active immunization with Streptococcus mutans glucan binding protein B (GBP-B) has been shown to induce protection against experimental dental caries. This protection presumably results from continuous secretion of salivary antibody to GBP-B, which inhibits accumulation of S. mutans within the oral biofilm. The purpose of this study was to explore the influence of short-term (9- or 24-day) pass...
