BACKGROUND Caries process is not a static one, but is dynamic with interspersed periods of demineralization and remineralization of enamel, intimately related and occurs episodically based upon the presence of cariogenic bacteria in dental plaque and the availability of refined carbohydrates for fermentation to organic acids. OBJECTIVES Early enamel caries could be reversed with avoidance of ...

aims: in our previous studies, we showed the inhibitory effects of punica granatum l. flower and rhus coriaria l. fruit water extracts on dental plaque accumulation by several bacteria, especially streptococcus mutans (s. mutans), on orthodontic wire by in vitro assays. in this study, the anti-cariogenic properties of the extracts were evaluated by assessing their effects on expression of glyco...

ABSTRACTIntroduction: Dental caries is a multifactorial disease that invades the hard tissues of teeth. among most common oral manifestations in children with autism spectrum disorders (ASD). ASD neurodevelopmental disorder characterized by deficits social interactions, communication difficulties, and restricted repetitive behavior. have higher risk dental due to their difficulty maintaining go...

An operon encoding enzymes of the agmatine deiminase system (AgDS) has been identified in the cariogenic bacterium Streptococcus mutans UA159. The AgDS is regulated by agmatine induction and carbohydrate catabolite repression. Ammonia is produced from agmatine at low pH, suggesting that the AgDS could augment acid tolerance.
