Summary
This study compared bone removal temperatures during third molar extraction. High-speed instruments generated less heat, indicating better bone preservation during oral surgery.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomaterials Science
- Surgical Technology
Background:
- Bone removal is crucial in third molar extraction.
- Heat generated during bone removal can impede bone healing.
- Understanding instrument-specific temperature variations is vital for optimizing surgical outcomes.
Purpose of the Study:
- To evaluate temperature variations during bone removal using different surgical instruments.
- To compare the thermal effects of high-speed turbine, implant motor, low-speed micromotor, and piezoelectric saw.
- To assess the impact of rotational speed on intraoperative temperature during bone removal procedures.
Main Methods:
- Bone removal was performed on pig mandibles around 20 posterior teeth.
- Constant saline irrigation was maintained using a syringe and needle.
- Temperature variations and surgical time were recorded for each instrument: high-speed turbine (400,000 rpm), implant motor (100,000 rpm), low-speed micromotor (20,000 rpm), and piezoelectric saw (30 kHz).
Main Results:
- Mean temperature variations were: 0.96°C (high-speed turbine), 1.38°C (implant motor), 2.22°C (low-speed micromotor), and 2.90°C (piezoelectric saw).
- Statistically significant differences in temperature variation were found between the high-speed turbine and the micromotor (p=0.009), and between the low-speed micromotor and the piezoelectric saw (p=0.04).
- Higher rotational speeds correlated with lower temperature variations and reduced surgical time.
Conclusions:
- Significant differences exist in temperature variations among instruments used in oral and maxillofacial surgery.
- High-speed instruments demonstrate lower temperature increases during bone removal compared to lower-speed or piezoelectric devices.
- Optimizing instrument selection based on rotational speed can minimize thermal damage and potentially improve bone repair post-extraction.

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.

Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
