Current status of dental metal allergy in Japan
ConclusionsDental metals, including nickel, palladium and zinc, which are indispensable to dental treatment in Japan, had high positivity rates in patch testing, and one-half of the patients improved following removal of the metal. Additionally, there were several patients with allergy to titanium. (Source: Journal of Prosthodontic Research)

Effect of different cleansing agents and adhesive resins on bond strength of contaminated zirconia
ConclusionsThe saliva and silicone disclosing medium contaminated zirconia should be cleaned with Phosphoric acid, Ivoclean or Hydrofluoric acid for 20 s prior to cementation with Panavia F2.0. However, the surface cleansing was not necessary when cementation with Superbond C&B. (Source: Journal of Prosthodontic Research)

Influence of block-out on retentive force of thermoplastic resin clasps: an in vitro experimental and finite element analysis
ConclusionsThis in vitro experiment suggested that a horizontal block-out is necessary even for a 0.5-mm undercut. The design of the resin clasp should be considered from two aspects: retentive force and deformation risk. (Source: Journal of Prosthodontic Research)

Effects of the loss and reconstruction of molar occlusal support on memory retrieval and hippocampal neuron density in rats
ConclusionsOur results suggest that the loss of occlusal support decreases the number of pyramidal cells in the hippocampus and impairs memory decoding and retrieval. However, this effect is suppressed by the reconstruction of occlusal support. (Source: Journal of Prosthodontic Research)

Leaching behaviors of computer-aided design/computer-aided manufacturing composite resin component elements immersed in water
ConclusionsFiller elements in CAD/CAM composite resins used in this study leached into purified water. The leached elements and its quantities greatly differed among materials and depend on the types of the oxides composing the filler. The amounts of leached elements varied in a temperature-dependent manner. (Source: Journal of Prosthodontic Research)

Effects of number of metal restorations and mandibular position during computed tomography imaging on accuracy of maxillofacial models
Conclusions: Accuracies of reproduced maxillary and mandibular models decreased with increasing numbers of metal restorations and in the closed mandibular position during CT scanning. (Source: Journal of Prosthodontic Research)

Influence of elastic modulus mismatch between dentin and post-and-core on sequential bonding failure
ConclusionsUsing failure criteria for cement adhesion, sequential changes of adhesion failure between dentin and post-and-cores were observed. Local stress concentrations leading to severe destruction of dentin were caused by not only materials of post-and-cores but their adhesive conditions to dentin. Nonlinear finite element analysis (FEA) using complex structure model which deals with alterations of interfacial condition between components could provide the simulation for the clinical failure of teeth restored with post-and-cores.

Microstructural, mechanical, ionic release and tarnish resistance characterization of porcelain fused to metal Co–Cr alloys manufactured via casting and three different CAD/CAM techniques
ConclusionsThe manufacturing procedure significantly affects the microstructure, porosity, and mechanical properties of Co–Cr alloys. In contrast, ionic release and tarnish resistance are independent of the manufacturing technique used. (Source: Journal of Prosthodontic Research)

Influence of decrease in the muscle activity during mastication on occurrence of the Stage II transport
ConclusionsThe present study supported the hypothesis that intentional decrease in the muscle activity during mastication affected the number of chewing strokes and the occurrence of St2Tr. Particularly, this tendency was noticeable during the mastication before the start of St2Tr. However, our results did not support a question as to the number of swallowing.

Longitudinal study on risk indicators for peri-implantitis using survival-time analysis
ConclusionsWithin the limitations of this longitudinal study on risk indicators for peri-implantitis, age, inadequate plaque control, insertion in the maxilla and less occlusal support of natural teeth correlated with peri-implantitis development. (Source: Journal of Prosthodontic Research)
