摘要

Introduction

To facilitate the luxation and excision of impacted teeth, it is frequently necessary to employ techniques such as osteotomy and tooth section during the surgical stages of tooth removal. Piezoelectric therapy is a useful technique for tooth section as it preserves important structures, such as the inferior alveolar nerve and soft tissue around the tooth.

Aim & Objectives

The aim of this study was to evaluate the time and temperature variations during the dental section procedure.

Method

Twenty teeth were selected by carbide 702 drill, Zecrya drill, 4138 diamond bur, and OSTEO 01 piezoelectric tip. The time was measured by digital chronometer, and the temperature was measured via thermocouples associated with the respective portable digital thermometers. The initial temperature and the maximum temperature during the procedure were recorded.

Results

It revealed an average temperature variation and standard deviation of 1.15 °C + 0.5 for the 702 carbide bur, 1.60 °C + 0.67 for the Zekrya carbide bur, 2.10 °C + 0.96 for the 4138 diamond tip, and 5.23 °C + 1.82 for the OSTEO1 piezoelectric tip. The average time required to perform the tooth section was 38 s for Carbide 702 in contrast to 285 s for the OSTEO 1 piezoelectric tip. The data obtained were tabulated and subjected to statistical analysis via ANOVA (p < 0.05), and the conventional variance was corrected for the time variable via ANCOVA (p < 0.05). The results show a direct relationship between time and temperature, where instruments with a reduced surgical time produced less heat and consequently a lower temperature variation.

Conclusion

The variation of temperature produced by the ultrasonic tip was greater than that produced by the high-rotation drills utilized in this investigation, and the time required to perform tooth section was shorter when the drills were used than when the piezoelectric drill was used. The carbides were more effective than the diamond tips for high-speed drills, and the high-rotation carbide drills are considered good options for the tooth section given the procedure less time and temperature variations.
