Oral health care behavior and frailty-related factors in a care-dependent older population
Conclusions Oral health care behavior, especially lower brushing and DSU frequency since the onset of care-dependency, is related to specific frailty-related factors in a care-dependent older population. Clinical significance Oral care-providers should be alert to the role of specific frailty-related factors, which are likely to reduce DSU and brushing frequency in the course of increasing frailty.

Effect of a novel quaternary ammonium silane cavity disinfectant on durability of resin –dentine bond
Conclusions The 2% QAS cavity disinfectant demonstrated greater cell viability compared to 2% CHX, with no adverse effect on immediate bond strength and preserved bond stability over time. Clinical significance Incorporation of 2% quaternary ammonium silane cavity disinfectant in the resin–dentine bonding protocol enhances the success rate of bonded restorations.

The effect of first and second premolar extractions on third molars: A retrospective longitudinal study
Conclusions The retromolar space and the position of third molars significantly change during orthodontic treatment in growing patients. Premolar extractions have a positive influence on the eruption space and vertical position of third molars, whereas they do not influence the angular changes of third molars. Due to the retrospective character of the study, these conclusions should be carefully reflected. Further prospective research is necessary for better insights into this complex topic. Clinical significance This study stresses the importance of considering the possible effects of orthodontic treatment on third molar...

Longevity of fiber-reinforced composite fixed partial dentures (FRC FPD) —Systematic review
Conclusions FRC FPDs demonstrated high overall survival with predictable performance outcomes. However, long-term performance remains unclear. Clinical significance FRC FPDs are viable medium-term management alternatives for replacing single anterior or posterior teeth in patients. (Source: Journal of Dentistry)

Fluoride concentration in saliva and biofilm fluid following the application of three fluoride varnishes
Conclusion The present study has shown that FV vary in their ability to deliver fluoride intra-orally potentially related to formulation differences. To what extent the present findings relate to clinical efficacy remains, however, to be determined. Clinical significance Clinical research that investigates fluoride release patterns into saliva and biofilm fluid from different FV products is insufficient. More research is needed to investigate different FV formulations for their efficacy in order to help clinicians make better evidence based treatment choices. (Source: Journal of Dentistry)

Imaging Resin Infiltration into Non-Cavitated Carious Lesions by Optical Coherence Tomography
Conclusion Resin infiltration can be increased by optimizing the etching process. Optical coherence tomography provides information about the process and degree of resin infiltration. Clinical significance Active acid application before resin infiltration is recommendable. (Source: Journal of Dentistry)

Translucent zirconia in the ceramic scenario for monolithic restorations: A Flexural Strength and Translucency comparison test
Conclusions The zirconia composition heavily influenced both the flexural strength and the translucency. Different percentages of Yittria and Alumina result in new materials with intermediate properties in between the conventional zirconia and lithium disilicate. Clinical indications for Zirconia Aadva NT should be limited up to three-unit span bridges. (Source: Journal of Dentistry)

Comparison of in vitro dentinal tubule occluding efficacy of two different methods using a nano-scaled bioactive glass-containing desensitising agent
Conclusions The application of transparent trays in combination with nano-scaled BG-containing desensitising paste could increase the dentinal tubule occluding effectiveness of the latter one and shorten the treatment time. Clinical relevance Transparent trays could be used in combination with BGs-containing desensitising paste as the containers of the latter one in order to increase the dentinal tubule occluding effectiveness. This could lead to the development of a new therapeutic technique for treating dentine hypersensitivity. (Source: Journal of Dentistry)

Release of monomers from composite dust
Conclusion Theoretically, composite dust may function as a vehicle to transport monomers deeply into the respiratory system. The results of this study may shed another light on the increasing incidence of respiratory disease among dental personnel, and more care should be taken to prevent inhalation of composite dust. Clinical significance Special care should be taken to prevent inhalation of composite dust, as the dust particles may release methacrylate monomers. (Source: Journal of Dentistry)

Degradation of optical and surface properties of resin-based composites with distinct nanoparticle sizes but equivalent surface area
Conclusion The optical properties of the tested materials were not dependent of the fillers’ surface area, while the surface properties were. Clinical significance Several factors influence the ageing resistance of the resin-based composites, including the surface area of the fillers and the amount and coupling treatment of them. The improvement of the material’s physical stability could avoid the premature replacement of dental restorations. (Source: Journal of Dentistry)

An approach to understanding tribological behaviour of dental composites through volumetric wear loss and wear mechanism determination; beyond material ranking
Conclusion It is proposed that the approach employed to use a combination of measurement and analytical techniques to quantify the wear facet volume (profilometry), wear trough (SEM) and material transfer (EDS) provides more useful information on the wear mechanism and the tribology of the system rather than relying on a simple wear ranking for the RBC materials as is routinely the case in dental research studies.

Effects of tooth-brushing force with a desensitising dentifrice on dentine tubule patency and surface roughness
Conclusions Brushing with NovaMin resulted in significant dentine tubule occlusion at 100g and 400g, but brushing with Na2PFO3 resulted in increased tubule patency. Surface roughness increased significantly at 400g brushing with NovaMin. There was no correlation between tubule patency and surface roughness. Clinical significance A NovaMin desensitising dentifrice resulted in tubule occlusion even at high brushing forces. There was minimal increase in surface roughness at the lower (100g) brushing force.
