To assess whether orthodontic debonding and onset of tooth sensitivity were related and if anterior and posterior teeth showed different sensitivity.
40 patients were divided into a trial group (group 1, at the end of the multibracket treatment) and a control group (group 2, not under treatment). After the application of compressed air and cold water to mandibular incisors and first molars, participants were asked to report the pain felt for each tooth using a 100-mm visual analogue scale. In group 1, assessment was performed just before debonding (T0), immediately after completion of debonding (T1) and 7 days after (T2). In group 2, values were assessed at the beginning of a follow-up visit (T0), at the end of the same visit (T1) and 7 days after (T2).
Considering overall teeth, statistical analyses showed significantly higher values in the trial group at T1 after both stimuli, especially after cold water, besides a significant difference between T0 and T2 values in the same group. Anterior teeth showed significantly higher VAS scores than posterior after the two thermal stimuli, except after air stimulation in group 1 at T2 and in group 2.
Orthodontic debonding leads to sensitivity to thermal stimuli especially in the anterior teeth, however pain level is restored within 7 days.
评估正畸去带和牙齿敏感的发生是否相关，以及前牙和后牙是否表现出不同的敏感性。
将 40 名患者分为试验组（1 组，多托槽治疗结束时）和对照组（2 组，未治疗）。在下颌切牙和第一磨牙应用压缩空气和冷水后，让参与者使用 100mm 视觉模拟量表报告每颗牙齿的疼痛感觉。在 1 组中，在去带前（T0）、去带完成后即刻（T1）和 7 天后（T2）进行评估。在 2 组中，在随访开始时（T0）、同一随访结束时（T1）和 7 天后（T2）评估值。
考虑到所有牙齿，统计分析显示，在两种刺激后，试验组在 T1 时的数值明显更高，尤其是在冷水刺激后，而且同一组在 T0 和 T2 之间的数值也有显著差异。在前牙和后牙两种热刺激后，前牙的 VAS 评分明显高于后牙，除了在 T2 时 1 组的空气刺激和 2 组的 T2 时的空气刺激。
正畸去带会导致对热刺激敏感，尤其是在前牙，但疼痛水平在 7 天内恢复。
