objectives: the purpose of current study was to compare the effect of aging on balance in different sensory conditions. methods & materials: in this cross sectional study we compared 20 healthy youth (with age 22.75±2.29) and 20 healthy older adults (with age 65.1±4.16) in single leg standing in different sensory conditions. sensory conditions were open eye/ hard surface (oehs), closed eye/ har...

introduction: this study investigated the fatigue and fracture modes of race and protaper rotary instruments. materials & methods: fatigue resistance was evaluated by rotating the files 30 ° or 60 ° and with 2 or 5mm radius of curvature. race taper 06 size 25 and protaper f1 files (n=40) were used. the number of rotations to failure was analyzed by two-way anova and independent sample     t-tes...
