Scaling and root planning (SRP) is still the gold standard of nonsurgical periodontal therapy, and it has been accompanied by several supportive therapies in recent years. One of the most studied methods is the diode laser, thanks to its thermal and bactericidal properties. Our trial intended to verify whether it could influence the chemical bond between calculus and the root surface.
The aim of the study was to assess the efficacy of the diode laser prior the mechanical removal of calculus in an in vitro application. The reduction in time and the number of strokes required to clean the untreated root surfaces were evaluated as primary outcomes. The pressure was considered as a secondary outcome.
A total of 75 extracted human teeth with subgingival calculus were assigned equally among three treatment groups (n = 25) according to the size of the occupied areas, which were classified by evaluating the pixel numbers. The groups were assigned to either no pretreatment application (A), Laser Diode Fox III (Sweden & Martina) (B) or Wiser Laser Evolution (Doctor Smile) (C). The weight for instrumentation was calibrated for an After Five curette (Hu-Friedy, Chicago). A new set of tools was used for each group, and the curettes were sharpened after each use with the Sidekick sharpener (Hu-Friedy, Chicago).
A Kruskal-Wallis test was used to assess the significance for each considered parameter. The results were statistically significant for each parameter for the two groups where the laser was used compared to the control group.
Despite the limitations of an in vitro study, data showed that the diode laser had an overall positive effect on root debridement, facilitating SRP in terms of stroke count, time, and pressure.
刮治和根面平整（SRP）仍然是非手术牙周治疗的金标准，近年来它已经与几种辅助疗法相结合。其中研究最多的方法之一是二极管激光，这要归功于它的热和杀菌特性。我们的试验旨在验证它是否能影响牙石与牙根表面之间的化学键。
本研究旨在评估二极管激光在机械去除牙石之前的体外应用效果。评估未处理根面清洁所需的时间和冲程数减少作为主要结果，压力作为次要结果。
共有 75 颗带有龈下牙石的人离体牙根据所占面积的大小平均分配到三组（n=25），根据评估像素数进行分类。将每组分别分配到不进行预处理（A）、二极管激光 Fox III（瑞典和玛蒂娜）（B）或 Wiser Laser Evolution（Doctor Smile）（C）。仪器的重量经过 After Five 挖器（Hu-Friedy，芝加哥）校准。每个组都使用一组新的工具，每次使用后用 Sidekick 磨刀器（Hu-Friedy，芝加哥）锐化挖器。
Kruskal-Wallis 检验用于评估每个考虑参数的显著性。与对照组相比，在使用激光的两组中，每个参数的结果均具有统计学意义。
尽管这是一项体外研究的局限性，但数据表明二极管激光对根面清创有整体积极影响，在冲程计数、时间和压力方面促进了 SRP。
