Does a complex intervention of oral hygiene advice (OHA) delivered with intra-oral scanner images, anti-gingivitis toothpaste and motivational reminders, improve oral health more than a standard of care control arm of fluoride toothpaste, with OHA without scanner images?
Adult participants with pre-existing gingivitis were randomised to intervention or control. Following enrolment, baseline and each subsequent visit (V) (3-weeks, V2; 3-months, V3; 6-months, V4) followed the same schedule. Bleeding on Probing (BOP) was assessed and Intra Oral Scan IOS(1) recorded. Plaque was disclosed, scored and re-scanned (IOS(2)). The intervention group received OHA with IOS images, control group receiving OHA without IOS images. Participants brushed with their allocated toothpaste (fluoride, control; anti-gingivitis, intervention), IOS(3) was recorded. Between visits participants brushed with their allocated toothpaste, intervention group received motivational reminders.
BOP scores from baseline were significantly improved in the intervention group compared to control at all visits for all surfaces (p<0.001); differences at V4 were 0.292 (all), 0.211 (buccal/labial) and 0.375 (lingual/palatal). Plaque scores from baseline pre-brushing to each visit pre- and post-brushing also favoured the intervention group, the difference always significant on lingual/palatal surfaces (p<0.05), significant for all but pre-brushing-V4 (p<0.05) on all surfaces, but only significant for pre-brushing-V3 (p<0.05) buccally/labially. Differences from baseline to post-brushing at V4 were: 0.200 (all), 0.098 (buccal/labial) and 0.291 (lingual/palatal).
A complex intervention comprising OHA delivered with IOS-images, anti-gingivitis toothpaste and motivational reminders improved gingival health more than existing standard of care-OHA together with a standard fluoride toothpaste over a 6-month period.
Intra-oral scans (IOS) are now frequently used in general dental practice for a variety of purposes. IOS use, in combination with motivational texts and an anti-gingivitis toothpaste, could be further deployed to promote oral hygiene behaviour change in patients and improve gingival health, in a cost-effective manner.
与使用口腔内扫描仪图像、抗牙龈炎牙膏和激励提醒的口腔卫生建议（OHA）的复杂干预措施相比，不使用扫描仪图像的 OHA 标准护理对照组是否能更有效地改善口腔健康？
患有先前存在的牙龈炎的成年参与者被随机分配到干预组或对照组。在入组后，基线和随后的每次就诊（V）（3 周，V2；3 个月，V3；6 个月，V4）都遵循相同的计划。评估探诊出血（BOP）并记录口腔内扫描（IOS（1）。显示菌斑，评分并重新扫描（IOS（2））。干预组接受带有 IOS 图像的 OHA，对照组接受不带 IOS 图像的 OHA。参与者使用他们分配的牙膏刷牙（氟化物，对照组；抗牙龈炎，干预组），记录 IOS（3）。在就诊之间，参与者使用他们分配的牙膏刷牙，干预组收到激励提醒。
与对照组相比，干预组在所有就诊时所有部位的 BOP 评分均显著改善（p<0.001）；V4 时的差异分别为 0.292（所有）、0.211（颊/唇）和 0.375（舌/腭）。基线至每次就诊时的菌斑评分在基线前刷牙和每次就诊前、后刷牙均有利于干预组，除 V4 前刷牙外（p<0.05），所有部位均有显著差异（p<0.05），仅在 V3 前刷牙时（p<0.05）颊/唇有显著差异。V4 时与基线相比的差异分别为：0.200（所有）、0.098（颊/唇）和 0.291（舌/腭）。
包含使用 IOS 图像、抗牙龈炎牙膏和激励提醒的 OHA 的复杂干预措施在 6 个月内改善了牙龈健康，优于现有的标准护理-OHA 加上标准氟化物牙膏。
口腔内扫描（IOS）现在在一般牙科实践中经常用于各种目的。以具有成本效益的方式，IOS 的使用与激励文本和抗牙龈炎牙膏相结合，可进一步用于促进患者的口腔卫生行为改变并改善牙龈健康。
