Various drill diameters (2.0\/ 2.2, 2.8, 3.5, 4.2\u00a0mm \u2205) and different cooling methods (without\/ with external saline irrigation) were investigated at room temperature (21\u00a0\u00b1\u00a01\u00b0C). Temperature changes were recorded in real time using two custom\u2010built multichannel thermoprobes in 1\u2010 and 2\u2010mm distance to the osteotomy site.
