Effect of Diamond and Carbide Burs on Dentinal Tubules and Predentin Diameter

OBJECTIVES: To find out the effect of Diamond and Carbide burs on diameter dentinal tubules predentin premolar teeth. METHODOLOGY: A Laboratory-based experimental study was conducted at anatomy department, Institute Basic Medical Sciences, Khyber University, from January 2018 to March 2018. Sixty premolars were obtained patients considering inclusion exclusion criteria. Six teeth extracted for control group A. Fifty-four maxillary mandibular in underwent cavity preparation carried by diamond bur (group B) twenty-seven other carbide C) removed a dental hospital Peshawar (RCD). They processing then stained with Eosin, Hematoxylin Masson's trichrome observe predentin. RESULTS: The diameters observed measured all samples both groups B C. No seen diameter. In Control group, less as compared Experimental C, i.e., 10-17.5µm whereas range (Group 12.5-25µm 20-37.5µm whereas. CONCLUSION: It concluded that comparison bur, is more beneficial than has no little effects
