The aim of this study was to evaluate and compare preprocedural dental anxiety levels and postprocedural pain perception in chronic periodontitis patients during conventional-staged root surface debridement (RSD) and single-stage RSD.
Thirty-seven adult generalized chronic periodontitis patients requiring RSD were recruited in this study. Preprocedural anxiety levels were assessed using a self-reported questionnaire and postprocedural pain perceptions were assessed using 0-10 cm visual analog scale. The subject population was divided into two groups: staged RSD ( = 18) and single-stage RSD ( = 19). Staged RSD patients visited four times as opposed to single-stage RSD patients. Data were subjected to Pearson Chi-square test, Mann-Whitney U-test, and Spearman's rank correlation.
There was no statistically significant difference in dental anxiety levels or pain perceptions in both the groups. Within Group 1, there was statistical significant difference in dental anxiety levels between visit 4 and visit 3 ( = 0.037) and pain perception between visit 3 and visit 1 ( = 0.005), visit 4 and visit 1 ( = 0.002), and visit 4 and visit 2 (0.04) was statistically significant. There was a positive correlation of anxiety questionnaire (Q1-Q4) to the pain score in Group 1 which was statistically significant and in single-stage RSD.
Conventional quadrant-wise RSD tends to cognitively condition the anxiety experience thus influencing pain experience.
本研究的目的是评估和比较慢性牙周炎患者在传统分期根面平整术（RSD）和单阶段RSD过程中的术前牙科焦虑水平和术后疼痛感知。
本研究招募了37名需要进行RSD的成年广泛性慢性牙周炎患者。术前焦虑水平采用自我报告问卷进行评估，术后疼痛感知采用0-10厘米视觉模拟量表进行评估。研究对象分为两组：分期RSD组（n = 18）和单阶段RSD组（n = 19）。分期RSD患者就诊4次，而单阶段RSD患者就诊1次。数据进行Pearson卡方检验、Mann-Whitney U检验和Spearman等级相关性分析。
两组患者的牙科焦虑水平或疼痛感知均无统计学显著差异。在第1组中，第4次就诊和第3次就诊之间的牙科焦虑水平存在统计学显著差异（P = 0.037），第3次就诊和第1次就诊之间的疼痛感知（P = 0.005）、第4次就诊和第1次就诊之间的疼痛感知（P = 0.002）以及第4次就诊和第2次就诊之间的疼痛感知（P = 0.04）均具有统计学显著性。在第1组和单阶段RSD中，焦虑问卷（Q1-Q4）与疼痛评分呈正相关，具有统计学显著性。
传统的象限式RSD倾向于在认知上调节焦虑体验，从而影响疼痛体验。
