The NiTi endodontic instruments were tested in fatigue to 1/2 and 3/4 of their fatigue life, at maximum strain amplitudes between 3.3 and 5.0%.
Series 29 #5 ProFile, together with #6 and #8 Quantec instruments, were tested in artificial canals with a 45-degree angle of curvature and 5-mm radius of curvature.
Following the approach of Brown (2006), at first the instruments were tested for configural invariance, second for metric invariance and finally for scalar invariance.
All of the scientific instruments were tested and most were turned off prior to the solar conjunction which occurred from October 7 to November 6, 2006.
The revised survey instruments were test-retested with fairly acceptable responses over a three-week period among 63 recruits in a third military camp in Norway (Heistadmoen).
These instruments were tested before use in the field.
Three instruments were tested: a SRH question and two VAS.
The instruments were tested in a pilot study prior to the main study.
Most instruments were tested in relatively small, homogenous samples recruited from a single setting.
Both instruments were tested on three GPs not included in the final sample.
Correlations between instruments were tested with the Spearman correlation test to investigate whether there was a relationship between them.
