The aim of this study is to compare the effectiveness of low-level laser irradiation to traditional topical fluoride treatment for treatment choices of dentinal hypersensitivity following scaling and root planing. The experimental group (15 patients) was treated with low-energy-level diode laser at each site of dentinal hypersensitivity following scaling and root planning. The control group (15 patients) received topical fluoride treatment (protective varnish for desensitization). All the patients were treated at baseline visit, and then at day 2 and 4 after the initial treatment; the pain was subjectively assessed by the patients as strong, medium, medium low, low, or no pain. Total absence of the dental hypersensitivity was reported in 26.66% of the examined group even after the second visit, compared to the control group where complete resolution of the hypersensitivity was not present after the second visit in any of the treated cases. Complete absence of pain was achieved in 86.6% of patients treated with laser and only in 26.6% in the fluoride treated group, after the third visit. Based on our findings, we conclude that low-energy biostimulative laser treatment can be successfully used for treatment of dental hypersensitivity following scaling and root planing.
本研究旨在比较低水平激光照射与传统局部应用氟化物治疗在龈下刮治和根面平整后牙本质过敏症治疗选择中的疗效。实验组（15 例患者）在龈下刮治和根面平整后，对每个牙本质过敏部位进行低能量水平二极管激光治疗。对照组（15 例患者）接受局部应用氟化物治疗（脱敏保护漆）。所有患者在基线访视时进行治疗，然后在初始治疗后第 2 天和第 4 天进行治疗；患者根据疼痛强度自我评估为强、中、中低、低或无疼痛。在第二次就诊时，检查组中甚至有 26.66%的患者报告完全没有牙本质过敏症，而在对照组中，在任何治疗病例中，第二次就诊时都没有完全消除过敏症。在第三次就诊时，接受激光治疗的患者中有 86.6%完全没有疼痛，而接受氟化物治疗的患者中只有 26.6%。基于我们的发现，我们得出结论，低能量生物刺激激光治疗可成功用于龈下刮治和根面平整后牙本质过敏症的治疗。
