The aim of this study was to explore muscle strength and its relation to exercise habits in Japanese. We used data from 3,018 men and 6,881 women aged 20-69 years and not using medications in a cross-sectional study. Exercise habits and muscle strength, i.e. grip strength and leg strength, were measured. Age-related changes in muscle strength were noted. Exercise habits were found in 984 men (3...

introduction: the aim of this in vitro study was to evaluate the effect of mta-based sealer (mta fillapex), eugenol-based sealer (dorifill) and an epoxy resin sealer (ah plus) on the bond strength of fiber posts cemented with a self-etch adhesive. materials and methods: the root canals of 72 maxillary incisors were prepared using the step-back technique after removing/cutting off the crowns. th...

objectives: this study sought to assess the effect of curcumin nanoparticles (curcnps) on antimicrobial property and shear bond strength (sbs) of orthodontic composite to bovine enamel. materials and methods: in this in vitro, experimental study, 1%, 5% and 10% curcnps were added to transbond xt composite. stainless steel brackets were bonded to 48 sound bovine incisors in four groups (n=12) us...

background: polymerization of resin‑modified glass‑ionomers (rmgis) is mediated through two competing mechanisms: an acid‑base reaction and a light‑dependent resin polymerization. furthermore, pre‑conditioning with acid has resulted in an increase in enamel bond strength of some rmgis. this in vitro study evaluated the effect of pre‑conditioning and/or delayed irradiation on bond strength of th...
