Abstract

OBJECTIVES
In this study we evaluated heat generation during the low-speed drilling procedure without irrigation.
MATERIALS AND METHODS
Ten artificial bone blocks that were similar to human D1 bone were used in this study. The baseline temperature was 37.0degrees C. We drilled into 5 artificial bone blocks 60 times at the speed of 50 rpm without irrigation. As a control group, we drilled into an additional 5 artificial bone blocks 60 times at the speed of 1,500 rpm with irrigation. The temperature changes during diameter 2 mm drilling were measured using thermocouples.
RESULTS
The mean maximum temperatures during drilling were 40.9degrees C in the test group and 39.7degrees C in the control group. Even though a statistically significant difference existed between the two groups, the low-speed drilling did not produce overheating.
CONCLUSION
These findings suggest that low-speed drilling without irrigation may not lead to overheating during drilling.
