The effects of silicone-based resilient denture liners on pain: A randomized controlled trial
ConclusionThis study concludes that edentulous patients wearing mandibular complete dentures with silicone-based resilient denture liners dull perception mandibular ridge mucosa and felt less pain than those without the liners. (Source: Journal of Prosthodontic Research)

Yttria-stabilized tetragonal zirconia polycrystal/resin luting agent bond strength: Influence of Titanium dioxide nanotubes addition in both materials
ConclusionY-TZP enhancements with TiO2-nts led to a higher SBS with Panavia F2.0, a 5% TiO2--nt concentration presented the highest bond strength. Modified Rely X U200 did not improve SBS. (Source: Journal of Prosthodontic Research)

Influence of mandibular free-end partial edentulism on the force exerted on maxillary anterior teeth
ConclusionsWhen the number of remaining teeth decreases in mandibular free-end partial edentulism, the burden on the maxillary anterior teeth increases. Our findings suggest that for patients with mandibular free-end partial edentulism, wearing a removable partial denture is effective in preserving the remaining teeth by reducing excessive stress.

Effectiveness of pretreatment with phosphoric acid, sodium hypochlorite and sulfinic acid sodium salt on root canal dentin resin bonding
ConclusionsBonding to root canal dentin was improved by applying sulfinic acid sodium salt in addition to treatment with phosphoric acid followed by sodium hypochlorite. The DOP of the adhesive resin was reduced by sodium hypochlorite and subsequently restored by applying sulfinic acid sodium salt. (Source: Journal of Prosthodontic Research)

Influence of curing modes on the degree of conversion and mechanical parameters of dual-cured luting agents
ConclusionsProvided adequate light curing is applied to a dual-cured luting agent, delaying the light curing or using a tack cure first to facilitate seating of a restoration may not have a significant impact on the luting agent’s final degree of conversion. However, using chemical cure only may result in inadequate cure of the luting agent and is recommended only for highly opaque restorations. (Source: Journal of Prosthodontic Research)

Fracture loads of screw-retained implant-supported zirconia prostheses after thermal and mechanical stress
ConclusionsThe monolithic zirconia prostheses exhibited significantly higher fracture loads than the bilayered prostheses. All the investigated types of screw-retained implant-supported zirconia prostheses appear sufficient to resist posterior masticatory forces during long-term clinical use.

Long-term performance of implant-supported metal–ceramic and all-ceramic single crowns
ConclusionAvoidance of full-coverage veneers significantly improves the clinical performance of implant-supported crowns, primarily reduces the incidence of chipping. (Source: Journal of Prosthodontic Research)

Color changes of polyetheretherketone (PEEK) and polyoxymethelene (POM) denture resins on single and combined staining/cleansing action by CIELab and CIEDE2000 formulas
ConclusionsΔE00 found to correlate well with ΔEab. Long term exposure of both materials showed a progressive discoloration in all except control baths. POM discolored more than PEEK in coffee, and combo baths but not in cleanser. Discoloration was smaller in combo bath (where a cleanser was also used) indicating the effectiveness of a cleanser to prevent long term discoloration of both materials.

The effects of hyperglycaemia on peri-implant tissues after osseointegration
ConclusionsAlthough hyperglycaemia could be associated with bone loss around implants with increased AGE production and RAGE expression, hyperglycaemia does not become a triggering factor of ligature induced peri-implantitis. (Source: Journal of Prosthodontic Research)

Effect of mechanical and chemical cleaning on surface roughness of silicone soft relining material
ConclusionsMechanical cleaning using a sponge did not increase the surface roughness of the material with a high Shore A hardness. Furthermore, neutral peroxide denture cleanser did not increase the roughness of materials with high and low Shore A hardness. (Source: Journal of Prosthodontic Research)

Comparison of adhesiveness of chewing gum to hard and soft denture base materials
ConclusionsAmong the hard denture base materials, zirconia recorded low adhesiveness and Re recorded high adhesiveness under both wet and dry conditions. The adhesiveness of Co was low under wet conditions but high under dry conditions. Among the soft denture base materials, SS under dry conditions recorded lower adhesiveness than that of AS. The adhesiveness of SS was low under both wet and dry conditions. (Source: Journal of Prosthodontic Research)

Digital protocol for creating a virtual gingiva adjacent to teeth with subgingival dental preparations
ConclusionsThe technique allows the dentist and laboratory technician to obtain a digital reproduction of the subgingival soft tissues around the prosthetic crown, unaffected by the collapse of the gingival sulcus when the provisional crown is removed, as well as an exact copy of the provisional restoration, making it possible to fabricate a definitive prosthesis that ensures precise anatomy, and so good compatibility with periodontal tissues.

Associations between tongue strength and skeletal muscle mass under dysphagia rehabilitation for geriatric out patients
ConclusionsFor patients with dysphagia, maintenance of skeletal muscle mass was associated with improvement of tongue strength in rehabilitation. This indicates that prevention of sarcopenia in dysphagia patients contributes to the effect of rehabilitation. (Source: Journal of Prosthodontic Research)
