Abstract

Introduction: Lasers are one of the most advantageous tools that have been used in a variety of medical fields. Soft tissue management is an important part of oral and maxillofacial surgery. There are different surgical procedures for management; one of them is laser surgery. The purpose of this study was to compare the dual-wavelength diode laser and the Er, Cr: YSGG laser to choose the most effective laser for a soft tissue incision in oral and maxillofacial surgery regarding temperature elevation. Methods: A dual-wavelength diode laser (810 and 980 nm) with 1.5 W and 2.5 W power outputs and an Er, Cr: YSGG (2780 nm) with 2.5 W and 3.5 W power outputs were used to make 50 incisions in six freshly dissected sheep tongues. The temperature means were measured at initial, maximum temperatures, as well as the temperature rise (difference between initial and maximum), and all were compared between the groups of soft tissue. Results: The lowest mean temperature rise was observed with a 2.5 W Er, Cr: YSGG laser, and the highest mean temperature rise was observed with a 2.5 W diode laser, and all samples from the two lasers showed a statistically significant difference (P<0.05) in the temperature rise except the 1.5 W diode, which is higher but not statistically significantly different from the 3.5 W Er, Cr: YSGG laser (P=0.100). Conclusion: The power output of 2.5 W of an Er, Cr: YSGG laser produced low levels of temperature rise compared to a diode laser and produced surgical incisions with a lower probability of heat damage to surrounding tissues.
双波长二极管激光与Er, Cr: YSGG激光在口腔软组织切口中的温升分析
激光是最有利的工具之一,已被用于各种医疗领域。软组织处理是口腔颌面外科的重要组成部分。有不同的外科治疗方法;其中之一就是激光手术。本研究的目的是比较双波长二极管激光和Er, Cr: YSGG激光,以选择最有效的激光用于口腔颌面外科软组织切口的温度升高。方法:采用功率分别为1.5 W和2.5 W的双波长二极管激光器(810和980 nm)和功率分别为2.5 W和3.5 W的Er, Cr: YSGG激光器(2780 nm)在6只新鲜解剖的羊舌上切开50个切口。测量初始温度、最高温度、温升(初始与最高温度之差)的温度均值,并比较各组软组织间的温度均值。结果:2.5 W Er, Cr: YSGG激光器的平均温升最低,2.5 W二极管激光器的平均温升最高,除1.5 W二极管激光器的温升高于3.5 W Er, Cr: YSGG激光器外,两种激光器样品的温升差异均有统计学意义(P= 0.05),但差异无统计学意义(P=0.100)。结论:与二极管激光器相比,功率为2.5 W的Er, Cr: YSGG激光器产生的温升水平较低,手术切口对周围组织的热损伤概率较低。
