Effect of air inlet ring opening on sonic handpiece performance

Intra‐canal cutting ability of MM 1500 files

“…Two power settings were chosen with the air inlet ring half or fully open. These were regulated using the graduated scale/air inlet ring which had been attached as described previously (Lumley et al 1994b(Lumley et al , 1996. The air pressure was fixed at 0.22 MPa and the foot control fully down and to the right.…”
