objectives: the purpose of the present study was to evaluate the effect of modified widman flap (mwf) surgery (as a periodontal treatment procedure) on maximum bite force (mbf; as an indicator of patient function). materials and methods: in this clinical trial, 24 patients were examined for their mbf before and at one, four and eight weeks after their mwf surgery. these recordings along with th...

A repeated-measures design is one in which multiple, or repeated, measurements are made on each experimental unit. The experimental unit could be a person or an animal, and repeated measurements might be taken serially in time, such as in weekly systolic blood pressures or monthly weights. The repeated assessments might be measured under different experimental conditions. Repeated measurements ...

objective: corrosion resistance is among the most important properties of metal alloys used in the oral cavity. consumption of acidic foods reduces the salivary ph and intensifies the corrosion of brackets and orthodontic wires. this study aimed to compare electro galvanic corrosion of different orthodontic brackets and wires and determine the amount of ions released into acidic artificial sali...

Katz (1978) has suggested that mild, fluctuating conductive hearing loss due to middle-ear anomalies may account for the language and attention problems of learning-disabled children. His position was extended here to include autism. Normal, learning-disabled, and autistic children received repeated impedance measures over 5 weeks. A repeated-measures ANOVA of central tendency and variability v...

We consider testing the main treatment effects and interaction effects in crossed two-way layout when one factor or both factors have large number of levels. Random errors are allowed to be nonnormal and heteroscedastic. In heteroscedastic case, we propose new test statistics. The asymptotic distributions of our test statistics are derived under both the null hypothesis and local alternatives. ...

1 The aim of the present study was to investigate the effects of motivating and 2 oudeterous (neither motivating nor demotivating) synchronous music on 400-metre 3 sprint performance while controlling for the potential confound of pre-performance 4 mood. A panel of volunteer Caucasian males (n = 20; mean age = 20.5, s = 1.2 years) 5 rated the motivational qualities of 32 musical selections usin...
