New high-speed diamond dental burs either sterilised or untreated were included while corroded dental burs or those with manufacturing defects were excluded.
Sample size was calculated using World Health Organisation (WHO) sample size calculator and using data from an earlier study.14,15 which reported the prevalence of bacterial contamination at 45% on dental burs. Absolute precision was kept at 20% and confidence interval (CI) at 95 %.
During collection, the burs were handled using sterile technique to prevent any contamination.
All the burs of test groups and positive control group were then used for access opening in permanent teeth and after the procedure the burs that were contaminated from bacteria, blood, saliva, tooth and tissue debris were carried using sterile technique to the sterilisation department except positive control group burs where different cleaning methods were used prior to steam autoclave.

30,000 intact buffalograss burs and 30,000 legume seeds were fed to each of three ruminally fistulated mixed-breed beef steers.
0.61 g/100 seeds, respectively, compared with about 1.37 g/100 for buffalograss burs. All seeds were purchased from commercial sources.
Intact burs and legume seeds for each steer were prepared by giving them a light coating of molasses ([less than]500 ml) and mixing them with ca.
Primed (Hays-treated) 'Texoka' buffalograss burs were fed in the first experiment.
