Orthodontic appliances complicate daily oral hygiene maintenance and enhance the formation of microbial biofilm on tooth surfaces and orthodontic appliances.
This trial was conducted to assess the effect of reminders on oral hygiene of patients during removable orthodontic treatment.
In this 2-arm parallel randomized controlled trial, 66 orthodontic patients with removable maxillary appliance were randomly allocated with 1:1 ratio to message reminders and the control group. The patients in the messaging group received one or two message reminders and educational videos weekly during the course of treatment. A single blinded examiner measured the plaque index (PI), gingival index (GI), and dental caries index of patients in both groups at baseline (T0) and one (T1), three (T2), and six (T3) months after the first day of treatment to assess their oral hygiene status during treatment.
A total of 30 patients in control group and 28 in reminder group completed the study. The PI and GI scores were increased neither in control group nor in message reminder group during T0 and T1, significantly. The PI and GI scores in message reminder group were significantly lower than those in the control group at T2 (PI: , GI: ) and T3 (PI: , GI: ). Slight significant increasing in the PI and GI score were found during T2 and T3 in message reminder group. Caries index showed no significant difference between two groups during study.
It seems that reminders can efficiently promote oral hygiene of patients undergoing removable orthodontic treatment.
正畸矫治器使日常口腔卫生维护变得复杂，并会促使牙面和正畸矫治器上微生物生物膜的形成。
本试验旨在评估提醒对可摘式正畸治疗患者口腔卫生的影响。
在这项双臂平行随机对照试验中，66名佩戴可摘式上颌矫治器的正畸患者按1:1比例随机分为消息提醒组和对照组。消息提醒组的患者在治疗过程中每周收到一两条消息提醒和教育视频。一名单盲检查者在基线时（T0）以及治疗首日之后的1个月（T1）、3个月（T2）和6个月（T3）测量两组患者的菌斑指数（PI）、牙龈指数（GI）和龋齿指数，以评估他们在治疗期间的口腔卫生状况。
对照组共有30名患者，提醒组有28名患者完成了研究。在T0和T1期间，对照组和消息提醒组的PI和GI评分均未显著增加。在T2（PI： ，GI： ）和T3（PI： ，GI： ）时，消息提醒组的PI和GI评分显著低于对照组。消息提醒组在T2和T3期间PI和GI评分有轻微显著增加。在研究期间，两组之间的龋齿指数没有显著差异。
提醒似乎可以有效促进接受可摘式正畸治疗患者的口腔卫生。
