The aim of this longitudinal study is to verify changes in the oral health-related quality of life of patients 180 days after treatment of dentin hypersensitivity (DH) with laser and cyanoacrylate.
This clinical, controlled, randomized, double-masked trial used a split-mouth design, and quadrants were randomized to receive either laser or cyanoacrylate treatments. All patients received both treatments. The study included 62 patients aged 12 to 60 years (mean: 31.4 years) in whom a total of 432 teeth were treated. Quadrants were randomly distributed into two groups: cyanoacrylate (n = 218 teeth) or laser (n = 216 teeth) treatment. DH was evaluated with air and cold stimuli at 24 hours, 30, 90, and 180 days after treatment. The Oral Health Impact Profile (OHIP-14) questionnaire was applied at baseline and 180 days after treatment.
There were statistically significant differences in the following OHIP-14 subscales before and after treatment: physical pain (P = 0.002), psychologic discomfort (P <0.001), psychologic disability (P = 0.003), social disability (P = 0.01), and total score (P <0.001). At the end of the study, 80.6% of participants reported an improvement in their condition.
There was a reduction in the impact of DH on the quality of life of study participants after interventions with laser and cyanoacrylate.
本纵向研究旨在验证激光和氰基丙烯酸酯治疗牙本质敏感症（DH）后 180 天患者口腔健康相关生活质量的变化。
这是一项临床对照随机双盲试验，采用分牙设计，将象限随机分为接受激光或氰基丙烯酸酯治疗组。所有患者均接受两种治疗。该研究纳入了 62 名年龄在 12 至 60 岁（平均 31.4 岁）的患者，共治疗了 432 颗牙齿。将象限随机分为两组：氰基丙烯酸酯（n = 218 颗牙）或激光（n = 216 颗牙）治疗组。使用空气和冷刺激在治疗后 24 小时、30 天、90 天和 180 天评估 DH。在基线和治疗后 180 天时应用口腔健康影响量表（OHIP-14）问卷。
治疗前后，OHIP-14 量表的以下子量表存在统计学差异：身体疼痛（P = 0.002）、心理不适（P <0.001）、心理障碍（P = 0.003）、社会障碍（P = 0.01）和总分（P <0.001）。研究结束时，80.6%的参与者报告病情有所改善。
激光和氰基丙烯酸酯干预后，DH 对患者生活质量的影响降低。
