The purpose of this study was to determine the perception of discomfort over time by a group of 70 patients undergoing orthodontic treatment. Patients who were selected for comprehensive orthodontic treatment completed questionnaires before insertion of separators and initial arch wires and after placement at 4 hours, 24 hours, and 7 days. The level of discomfort during these time periods was assessed by a visual analogue scale. The results showed a significant increase in the level of discomfort after insertion of either separators or arch wires at 4 hours and 24 hours, but not at 7 days. No significant difference was found in the level of discomfort of patients more than 16 years of age compared with those 16 years and under. No significant difference in discomfort was found between the sexes. These results are useful in relating expectations of discomfort to patients who undergo orthodontic treatment.
本研究的目的是确定一组70名接受正畸治疗的患者在一段时间内对不适的感知情况。被选入接受全面正畸治疗的患者在放置分离器和初始弓丝之前、之后4小时、24小时和7天时完成问卷。这些时间段内的不适程度通过视觉模拟量表进行评估。结果显示，在放置分离器或弓丝后的4小时和24小时，不适程度显著增加，但在7天时没有。16岁以上患者与16岁及以下患者在不适程度上没有显著差异。性别之间在不适方面也没有显著差异。这些结果对于让接受正畸治疗的患者了解对不适的预期很有帮助。
