Inter-examiner reliability was examined on a subset of 50 randomly selected burs and agreement between two investigators was determined using Kappa statistics that turned out to be excellent at 0.80.
There were 210 burs which were divided into 6 groups of 35(16.66%) each.
Among the test groups, 27(77.1%) dental burs in Group-1, 29(82.8%) in Group-2 and 27(77.1%) in Group-3 demonstrated contamination I In Group-4, 24(68.5%) dental burs showed contamination after staining with the dye.
Table-2: Frequency of contamination in the used burs subjected to different pre-cleaning methods.
The frequency of contamination was significantly associated with the sites of burs (p<0.05), and among the different sites, the head portion of the dental burs was the most frequently contaminated site (p<0.003) (Table-3).
sampling-time interaction, burs initially were numerous but declined significantly at each subsequent sampling time.

In early phases of our study, it was noted that intact burs were difficult to separate from fine fiber in feces or rumen digesta with our wet separation method, which prompted a closer examination of the bur structure.
Passage of legume seeds peaked during period 2, while passage of burs and caryopses was low and statistically uniform (P[greater than]0.05) across the 4 periods.
(1994) fed buffalograss burs to yearling Hereford steers, but they did not determine percentage bur survival.
'It is for this reason that BURS recently embarked on an extensive review of the GTP.
Mr Morris also noted that the improvements that the BURS intended to introduce in the GTP were in recognition of the fact that tax and customs administration were complex and gradually evolving.
