Chlorhexidine and green tea extract reduce dentin erosion and abrasion in situEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Objectives: This in situ/ex vivo study aimed to analyse the impact of possible MMP-inhibitors (chlorhexidine and green tea extract) on dentin wear induced by erosion or erosion plus abrasion.Methods: Twelve volunteers took part in this cross-over and double-blind study performed in 4 phases of each 5 days. Bovine dentin samples were worn in palatal appliances and subjected to extraoral erosion (4 times/day, Coca-Cola, 5min) or erosion plus abrasion (2 times/day, fluoride-free toothpaste and electrical toothbrush, 15s/sample). Immediately after each erosion, the appliances were reinserted in the mouth and the oral...

Probing nano-scale adhesion force between AFM and acid demineralized intertubular dentin: Moist versus dry dentinEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract: Objective: The aim of this study was to investigate the effect of dentin dryness on the variation in the probed nano-scale adhesion force between an AFM silicon nitride tip and demineralized intertubular dentin collagen fibrils network surface.Methods: Dentin specimens were etched with 37% phosphoric acid for 15s and then divided into three groups. Specimens of the first two groups were air-dried for 5 or 10s (DH5s and DH10s), respectively, whereas specimens of the third group were left in the hydrated condition (H). For each group, Force curves were characterized by contact-mode AFM and the adhesion force (Fad) ...

Reaction kinetics of sodium ascorbate and dental bleaching gelEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: This in vitro study showed that the amount of sodium ascorbate required for reduction of hydrogen peroxide is directly related to the concentration of the latter. In addition, the reaction kinetics between oxidant and antioxidant showed that a longer application time for sodium ascorbate does not influence the effectiveness of the reaction and that 5min is sufficiently long for this antioxidant to exert an antioxidant effect.

The literature was explored to determine the current status for post-endodontic restorative management of these teeth.Data and sources: The authors explored multiple search engine databases to November 2008. Experiments included in the review involved simulated human or animal immature teeth with mineral trioxide aggregate as an apical plug. The experiments were designed to assess and compare the fracture strength of teeth restored with various materials. Studies that did not fulfil inclusion criteria were omitte...

In vitro analysis of inhibitory effects of the antibacterial monomer MDPB-containing restorations on the progression of secondary root cariesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study aimed to analyze in vitro inhibitory effects of restorative materials containing the antibacterial monomer 12-methacryloyloxydodecylpyridinium bromide (MDPB) on the formation of artificial secondary root caries lesions.Methods: Class V cavities (2mm×2mm) were prepared in 75 human root fragments. Specimens were randomly divided into five groups (n=15 fragments per group) and restored as follows: (I) MDPB-free adhesive system+MDPB-free composite (negative control); (II) resin modified glass ionomer (RM-GIC; positive control); (III) MDPB-free adhesive system+MDPB-containing composite (2.83% MDPB); (IV) MDPB-contai...

Anxiety and pain during dental injectionsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Pain felt during dental injections is dependent on dental anxiety, fear of dental pain, fear for the injection, gender and amount of injection fluid (rather than the use of surface anesthesia). In other words, some patients are expected to feel elevated levels of pain during dental injection and would benefit from extra attention and care from the dentist. (Source: Journal of Dentistry)

The relationship of alcohol dependence and alcohol consumption with periodontitis: A systematic reviewEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: Alcohol consumption can be considered a risk indicator for periodontitis. Longitudinal studies on the association of alcohol dependence and alcohol consumption with periodontitis are needed to confirm the association or not. (Source: Journal of Dentistry)

Summary and conclusions: Where now?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This symposium commenced by highlighting the importance of the mouth as a diagnostic portal for diseases of the body and as a window into whole body wellbeing. The remainder of the meeting focussed on exploring the evidence base for, and the strength of associations between, periodontal inflammation and systemic chronic inflammatory disorders. Specifically discussed were type 2 diabetes and atherogenic vascular diseases (AVD). (Source: Journal of Dentistry)

Resolution of inflammation-unraveling mechanistic links between periodontitis and cardiovascular diseaseEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Periodontitis is considered a Gram negative infection. Extensive data accumulated in recent years point to the fact that the tissue destruction that characterizes periodontitis is mediated by the host response; it is not due to direct actions of bacterial virulence factors. Hence, periodontitis is now being characterized as an inflammatory disease induced by microorganisms. (Source: Journal of Dentistry)
