in order to deermine the effect of root canal cealer on microleakage of obturated root canal by lateral condensation technique(LCT) with and without tug-back(TB).seventy exteracted single root canal teeth were examined.after preparation of root canal with step-back technique,teeth were divided to six groups as follows:5 teeth as positive control group that obturated by LCT with gutta-perch itho...

Timed UP and Go Test (TUG) is conventionally used as predictor of falls in adults. Routine daily activities include multiple tasks performed concurrently. When two or more tasks (Dual/Triple test) needed to be carried out concurrently, task performance declined at least in one of them. Our study aimed to find temporal and demographic variations in the performance after adding a cognitive, motor...

Abstract This study aimed to investigate the effect of different activations on properties bio-based activated carbons (BACs) for water treatment. BACs were produced via pyrolysis by carbonization stage and followed four activation procedures. Chemical included introduction metal oxides or alkali structure sawdust-derived BACs, resulting in iron-activated carbon (BAC-Fe), copper-activated (BAC-...

OBJECTIVE To investigate the correlations of scores on the Timed Up and Go (TUG) test and the Single Leg Stance (SLS) test with stability scores on the Biodex Balance System (BBS) in healthy adults. METHOD The postural balance of 73 participants was measured on the TUG and SLS tests and with the Overall Stability Index (OSI) on the BBS. The participants were divided into groups by age and by ...

the contamination of water by toxic heavy metals is a world-wide environmental problem. discharges containing cadmium, in particular, are strictly controlled due to the highly toxic nature of this element and its tendency to accumulate in the tissues of living organisms. low concentration (below 5 mg`/l) of cadmium is difficult to treat economically using chemical precipitation methodologies. i...

Objectives The aims of this study were to quantify tug-back by measuring the pulling force and investigate the correlation of clinical tug-back pulling force with in vitro gutta-percha (GP) cone adaptation score using micro-computed tomography (µCT). Materials and Methods Twenty-eight roots from human single-rooted teeth were divided into 2 groups. In the ProTaper Next (PTN) group, root canal...

SUMMARY: Osteoporotic Brazilian women balance was evaluated by timed up and go test (TUG) and to the Berg balance scale (BBS). In the BBS, women with and without osteoporosis had normal range scores, even with history of fall. In the TUG test, women with osteoporosis were slower, but in the normal parameter. Results suggest that the references values of these tests are not appropriate for Brazi...
