Abstract

Background: The dentist believes that pressing harder on the tooth enhances the cutting effectiveness of the bur performance. The aim of the study: was to evaluate the effectiveness of carbide fissure bur in cutting dentin with light, moderate and heavy work load.
Materials and Methods: The cutting of carbide bur under different work load was evaluated on dentin specimens mounted in acrylic blocks. Group I: Cutting performed with light work load (=25g), Group II: Cutting performed with moderate work load (=100g), Group III: Cutting performed with heavy work load (=175g). Ten cuts were performed with each work load and atotal of 30 cutting rates or CRs (mm/sec.) were recorded and were statistically analyzed using analysis of variance (ANOVA) test, student t-test.
Results: A significant difference (P< 0.5) appeared between CRs of group I and III, and between group II and III.
Conclusion: The effectiveness of carbide fissure bur in cutting dentin markedly reduced with heavy work load.
