Dentin hypersensitivity can interfere with optimal periodontal care by dentists and patients. The pain associated with dentin hypersensitivity during ultrasonic scaling is intolerable for patient and interferes with the procedure, particularly during supportive periodontal therapy (SPT) for patients with gingival recession.
This study proposed to evaluate the desensitizing effect of the oxalic acid agent on pain caused by dentin hypersensitivity during ultrasonic scaling.
This study involved 12 patients who were incorporated in SPT program and complained of dentin hypersensitivity during ultrasonic scaling. We examined the availability of the oxalic acid agent to compare the degree of pain during ultrasonic scaling with or without the application of the dentin hypersensitivity agent. Evaluation of effects on dentin hypersensitivity was determined by a questionnaire and visual analog scale (VAS) pain scores after ultrasonic scaling. The statistical analysis was performed using the paired Student t-test and Spearman rank correlation coefficient.
The desensitizing agent reduced the mean VAS pain score from 69.33 ± 16.02 at baseline to 26.08 ± 27.99 after application. The questionnaire revealed that >80% patients were satisfied and requested the application of the desensitizing agent for future ultrasonic scaling sessions.
This study shows that the application of the oxalic acid agent considerably reduces pain associated with dentin hypersensitivity experienced during ultrasonic scaling. This pain control treatment may improve patient participation and treatment efficiency.
牙本质敏感会干扰牙医和患者进行最佳的牙周护理。在超声洁治过程中，与牙本质敏感相关的疼痛对患者来说难以忍受，会干扰操作，尤其是在为牙龈退缩患者进行支持性牙周治疗（SPT）期间。
本研究旨在评估草酸制剂对超声洁治过程中牙本质敏感所致疼痛的脱敏效果。
本研究纳入了12名参与SPT项目且在超声洁治过程中抱怨牙本质敏感的患者。我们检测了草酸制剂的可用性，以比较使用或不使用牙本质敏感剂时超声洁治过程中的疼痛程度。通过问卷调查和超声洁治后视觉模拟量表（VAS）疼痛评分来评估对牙本质敏感的影响。采用配对学生t检验和Spearman等级相关系数进行统计分析。
脱敏剂使平均VAS疼痛评分从基线时的69.33±16.02降至使用后的26.08±27.99。问卷调查显示，超过80%的患者表示满意，并要求在未来的超声洁治疗程中使用脱敏剂。
本研究表明，草酸制剂的应用可显著减轻超声洁治过程中牙本质敏感所致的疼痛。这种疼痛控制治疗可能会提高患者的参与度和治疗效率。
