TL;DR: Regular and frequent PP intake may help protect against oral cancer, while human studies are needed to confirm the promising preventive activity against periodontal disease and caries.

TL;DR: Elections of accuracy and precision of measuring systems and considerations of acceptability and perceptibility of a color difference are reviewed, and applications of color measurements to important appearance characteristics of natural and restorative materials are briefly introduced.

TL;DR: The use of amalgam was negligible and the material was predominantly replaced by resin based composites in first and replaced restorations, with secondary caries risk and experience of operator influenced longevity of replacements.

TL;DR: The porcelain-veneered zirconia crowns (NobelProcera) showed good clinical results, were well accepted by the patients, and only few complications were reported over the 3-year follow-up period.

TL;DR: The incorporation of DMAE-CB can render dental adhesive with contact antibacterial activity after polymerization via influencing the growth, adherence and membrane integrity of S. mutans.

TL;DR: Zirconia conditioning with the experimental hot etching solution may enhance ceramic roughness and improve the surface area available for adhesion allowing the formation of micromechanical retention.

TL;DR: Evaluated in vitro behaviour of all-ceramic zirconia molar crowns found an optimized core design reduced number and surface area of occurring chippings and a variation of the gap thickness showed no significant influence on the in vitro performance.

TL;DR: The composite cements evaluated in this study created perceptible color differences with particular combinations of die material, cement and ceramic crown.

TL;DR: The possible MMP-inhibitors tested in this study seem to be a promising preventive measure to reduce dentin erosion-abrasion, but their mechanism of action needs to be investigated in further studies.

TL;DR: The finding that TM reduced erosive tooth wear involving toothbrush abrasion, probably by remineralizing and lubricating eroded tooth surfaces, may have implications in the management of tooth wear.

TL;DR: The treatment with supplementary light showed significantly greater bleaching-dependent changes in color compared to treatment without light when assessed using instrumental methods, and the same was determined for the visual method with Vita Bleachedguide 3D-Master.

TL;DR: CXH digluconate at 2% was able to diminish loss of microtensile bond strength over time associated to both etch-and-rinse and self-etch adhesives, and lower concentration of CHX (0.2%) was not able to diminished the loss of bond strengthover time when associated to theSelf-etch adhesive CTSB.

TL;DR: Toothbrush abrasion has a synergistic effect with erosion on substance loss of human enamel, polyacid-modified composite and glass-ionomer cement, and the acid- and abrasive-resistance of humanEnamel was lower compared to restorative materials.

TL;DR: Sandblasting is an effective surface treatment for roughening surfaces of In-Ceram Spinell and although CO(2) laser irradiation does not increase surface roughness, it reveals the highest bond strength.

TL;DR: Chlorhexidine can preserve dentin bond as long as the concentration of chlorhexidine in the primer is higher than or equal to 0.1%, as well as in the 0.5% and 1.0% groups.

TL;DR: It is suggested that there is strong evidence showing that sodium hypochlorite adversely alters the mechanical properties of root dentine, when used as an endodontic irrigant.

TL;DR: Chlorhexidine reduced mTBS and produced pronounced nanoleakage when PF and UC were luted to dentine, while there was no adverse effect on coupling of ARC.

TL;DR: Females achieved significantly better shade matching results than males, indicating that gender plays an important role in shade matching.

TL;DR: Although the new two self-etch adhesives revealed a tight interaction at both enamel and dentin, their bond strength to both tooth tissues was generally lower than that of the control adhesive.

TL;DR: Clinical performance was satisfactory for both glass-fiber post designs and for both core build-up materials, and survival was higher for teeth retaining four and three coronal walls.

TL;DR: 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).

TL;DR: Enamel can be regarded as a functionally graded natural biocomposite which will require special attention using numerical analysis to fully appreciate the consequences of such a structure for the mechanical behaviour of teeth and restorations placed therein.

TL;DR: Abrasion of eroded dentin increased along with the RDA-value of the Toothpaste slurry and with decreasing filament diameter of the toothbrush.

TL;DR: The objective of this study was to set a gold standard for the color difference (DeltaE) at which all-ceramic crowns cannot be distinguished from natural teeth.

TL;DR: This study evaluated influence of different shade guides and respective shade matching methods on shade matching results and to analyze user satisfaction with these products and methods to determine Linearguide 3D-Master was superior in a subjective evaluation.

TL;DR: Marginal degradation of the resin cement and deterioration of the all-ceramic materials during clinical function determine the clinical long-term performance of partial coverage restorations.

TL;DR: Full-coverage all-metal crowns have longer survival times before re-intervention than metal-ceramic crowns and all-cer ceramic crowns, and root fillings are associated with reduced survival time of the crowns examined in this study.

TL;DR: Alcohol consumption can be considered a risk indicator for periodontitis and longitudinal studies on the association of alcohol dependence and alcohol consumption withperiodontitis are needed to confirm the association or not.

TL;DR: For the PCCs, the simplified designs (Groups II and III) demonstrated superior results compared to the traditional cusp capping design (Group I), and the marginal gaps were smaller than the internal gaps in all groups.

TL;DR: The use of a CPP-ACP paste had a protective effect on enamel demineralization in an in vitro model using Atomic Force Microscopy (AFM).
