Materials and Methods: Thermocouple technology was used to measure temperature level generated while drilling during osteotomy procedure for implant place in a bovine femoral cortical bone model. Drilling was accomplished by using milling machine .External irrigation at a constant ratio was used. The temperature of this irrigating solution was stabilized at 5°c and 25°C and The drilling depth was 8 mm and diameter of 2mm. Heat measurements were recorded after the final drilling for each irrigating solution in addition to time necessary to drop to base line level was recorded . Results: Results showed that cooled solution at 5 °C can decrease the temperature to a significant level better than solution at room temperature. In addition time needed to return to base line temperature levels is less than when using solution at room temperature. Conclusions: It can be concluded that the using cold irrigating solution can decrease the heat generated at implant site preparation consequently leading to decrease damage in the bone.
