The purpose of this study was to evaluate and compare clinically the efficacy of desensitizer toothpaste alone and in combination with the diode laser in the management of dentin hypersensitivity (DH), as well as both the immediate and late therapeutic effects on teeth with gingival recessions.
In total, 52 teeth diagnosed with DH in 13 (seven women, six men, aged 16-48 years) healthy adult patients were included in this study, and teeth were randomly divided equally into two groups: the test group, which received treatment with desensitizer toothpaste and GaAlAs (diode) laser, and the control group, treated with desensitizer toothpaste. DH was assessed by means of an air stimulus, and a visual analogue scale (VAS) was used to measure DH. The selected teeth in the test group received laser therapy for three sessions. Teeth subjected to diode-laser treatment were irradiated at 100 mW for 25 sec at 808 nm, with continuous-emission, noncontact mode, perpendicular to the surface, with scanning movements on the region of exposed root surfaces.
Significant reduction of DH occurred at all times measured during the three treatment sessions in the test group. When compared with the means of the responses in the three treatment sessions of the two groups, the test group showed a higher degree of desensitization in teeth with gingival recession than did the control group (p < 0.001). The immediate and late therapeutic effects of the diode laser were more evident compared with those of desensitizer toothpaste.
Within the limitations of the present study, a significant effect of combined desensitizer toothpaste and diode laser therapy occurs in the treatment of desensitization of teeth with gingival recession. Desensitizer toothpaste appears to have the therapeutic potential to alleviate DH. Conversely, diode laser can be used to reduce DH.
本研究旨在临床评估和比较脱敏牙膏单独使用以及与二极管激光联合使用在治疗牙本质过敏（DH）方面的疗效，以及对伴有牙龈退缩牙齿的即时和远期治疗效果。
本研究共纳入13名（7名女性，6名男性，年龄16 - 48岁）健康成年患者中诊断为DH的52颗牙齿，并将牙齿随机平均分为两组：试验组接受脱敏牙膏和GaAlAs（二极管）激光治疗，对照组仅接受脱敏牙膏治疗。通过空气刺激评估DH，并使用视觉模拟量表（VAS）测量DH。试验组中选定的牙齿接受3次激光治疗。接受二极管激光治疗的牙齿在808nm波长下以100mW的功率连续发射、非接触模式垂直于表面照射25秒，在暴露的根面区域进行扫描移动。
试验组在三个治疗阶段的所有测量时间点，DH均显著降低。与两组三个治疗阶段的反应均值相比，试验组中伴有牙龈退缩的牙齿脱敏程度高于对照组（p < 0.001）。与脱敏牙膏相比，二极管激光的即时和远期治疗效果更明显。
在本研究的局限性内，脱敏牙膏与二极管激光联合治疗对伴有牙龈退缩牙齿的脱敏有显著效果。脱敏牙膏似乎具有缓解DH的治疗潜力。相反，二极管激光可用于减轻DH。
