Abstract: Objective    To study the influence of a telephone follow-up on patients′    conscious orthodontic pain and anxiety during invisible orthodontic treatment. Methods    A total of 120 first-visit orthodontic patients who were wearing invisible orthodontic treatment from January 2021 to December 2021 in Department of Orthodontics，Hospital of Stomatology，Xi′an Jiaotong University，were randomly divided into the care phone group（n = 40），ordinary telephone group（n = 40）and control group（n = 40）. Follow-up was made six hours after wearing the appliance. The care phone group received a telephone call demonstrating care or reassurance and offering guidance to their questions；the ordinary telephone group received an attention-only telephone call thanking them for participating in the study；the control group received no telephone call. Visual analogue scale（VAS）and generalized anxiety disorder（GAD-7）were used to evaluate the degree of pain and anxiety at 6 hours and 1，2，3，4，5，6 and 7 days after wearing the appliance. Results    Four of 120 patients lost follow-up，including one in care phone group，one in ordinary phone group and two in control group. The loss of follow-up rate was 3.3% . At 6 hours and 1，2 and 3 days after wearing the appliance，there were significant differences in VAS scores in care phone group and ordinary phone group compared with the control group（P < 0.05）. At 1，2，3，4 and 5 days after wearing the appliance，there were significant differences in GAD-7 scores in care phone group and ordinary phone group compared with the control group（P < 0.05）. There was no significant difference in VAS and GAD-7 scores between care phone group and ordinary phone group at each time point（P > 0.05）. Conclusion    In the invisible orthodontic treatment，telephone call can reduce patients′    conscious pain and anxiety. However，the content of telephone follow-up may not affect the pain and anxiety of patients.

摘要： 目的    研究电话随访对无托槽隐形矫治患者正畸疼痛和焦虑的影响。方法    选取2021年1—12月于西安交通大学口腔医院正畸科就诊的需行无托槽隐形矫治初诊患者120例，随机分为关怀电话组、普通电话组和对照组，每组40例。佩戴矫治器后6 h进行随访，关怀电话组电话随访内容为表达关心，并对患者遇到的问题提供相应的指导；普通电话组仅对患者在这项研究中提供的帮助表示感谢。对照组不进行电话随访。佩戴矫治器后6 h及1、2、3、4、5、6、7 d，患者采用视觉模拟评分量表（visual analogue scale，VAS）和广泛性焦虑量表（generalized anxiety disorder，GAD-7）对疼痛和焦虑程度进行评分。结果    120例患者失访4例，其中关怀电话组和普通电话组各1例、对照组2例，失访率为3.3%。在佩戴矫治器后6 h及1、2、3 d，关怀电话组和普通电话组患者VAS评分与对照组比较，差异均有统计学意义（均P < 0.05）；在佩戴矫治器后1、2、3、4、5 d，关怀电话组和普通电话组患者GAD-7评分与对照组比较，差异均有统计学意义（均P < 0.05）；而关怀电话组和普通电话组患者的各时间点VAS、GAD-7评分比较，差异均无统计学意义（均P > 0.05）。结论    在无托槽隐形矫治中，电话随访可减轻患者的自觉疼痛和焦虑程度，但电话随访内容可能不会对患者的疼痛和焦虑产生影响。
