Experiments in dogs showed that drilling at the surface of bone provokes damage which increases with the number of revolutions per minute. Polychrome sequence marking and histological tests demonstrated that filling up of bony defects started later with turbine-driven drills than with drills of 2,000 r.p.m. and has not even been completed after eight weeks. It is therefore recommended to abstain from using turbines in drilling at the surface of bone.
