BACKGROUND/AIM Glass ionomer cements (GIC) belong to the group of polycarboxyl cements, and one of the principal characteristics of these materials is their anticariogenic potential of fluorine release into saliva and enamel-dentin substance. The aim of this study was to examine the content of released fluorine from GIC restorations (Fuji IX, GC, Japan) of young permanent teeth in the medium of...
This in vivo study assessed plaque pH in subjects following the consumption of different dairy products. After receiving parental consent to participate, subjects (12-15 years old) were asked to refrain from brushing their teeth for 48 hours prior to the study. At baseline, plaque pH was determined at 4 different sites. Each of the subjects was then assigned randomly to 1 of 4 subgroups and eac...
Tooth decay is an infectious disease, whose main causative agent identified is Streptococcus mutans (S. mutans). Diverse treatments have been used to eradicate this microorganism, including propolis. To date, it has been shown that polyphenols from Chilean propolis inhibit S. mutans growth and biofilm formation. However, the molecular mechanisms underlying this process are unclear. In the prese...
OBJECTIVES The antibacterial activity of Coffea canephora extract was evaluated in vitro against Streptococcus mutans and Streptococcus sobrinus. The viability of planktonic cells was analysed by susceptibility tests (MIC and MBC) and time-kill assays. The effect of the extract on dental demineralisation was also investigated. METHODS Primary 1st molar fragments (n=24) were inoculated with a ...
This study investigated the effect of CO2 laser irradiation on the inhibition of secondary caries on root surfaces adjacent to glass ionomer cement (GIC) or composite resin (CR) restorations. 40 dental blocks were divided into 4 groups: G1 (negative control): cavity preparation + adhesive restoration with CR; G2: (positive control) cavity preparation + GIC restoration; G3: equal to group 1 + CO...
Discussion, which can get spirited, has been going on about fluoride’s primary mode of action for some years. In the early days of fluoride research, it was assumed that the anticaries benefits of fluoride came from preemptive effects; however, posteruptive action was soon evident. Today the primacy of the posteruptive hypothesis is hardly questioned; remaining questions concern the role of pre...
Streptococcus mutans, with the ability of high-rate acid production and strong biofilm formation, is considered the predominant bacterial species in the pathogenesis of human dental caries. Natural products which may be bioactive against S. mutans have become a hot spot to researches to control dental caries. LongZhang Gargle, completely made from Chinese herbs, was investigated for its effects...
Glass ionomer cements (GIC) are dental restorative materials that are suitable for modification to help prevent dental plaque (biofilm) formation. The aim of this study was to determine the effects of incorporating casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) into a GIC on the colonisation and establishment of Streptococcus mutans biofilms and the effects of aqueous CPP-ACP on es...
AIM The aim of the present study was to evaluate the anticar-iogenic efficacy of hot and cold aqueous extracts of Terminalia chebula against Streptococcus mutans as an oral rinse and also to discover the acceptability of the mouthwash in children. SETTINGS AND DESIGN Sixty children between 8 and 12 years with high caries risk were selected. MATERIALS AND METHODS 10% concentration of hot and...
1,5-Anhydro-D-fructose (AF) was first found in fungi and red algae. It is produced by the degradation of glycogen, starch and maltosaccharides with α-1,4-glucan lyase (EC 4.2.2.13). In vivo, AF is metabolized to 1,5-anhydro-D-glucitol (AG), ascopyrone P (APP), microthecin and other derivatives via the anhydrofructose pathway. The genes coding for the enzymes in this pathway have been cloned, en...
