研究目的:

根据正畸患者龋易感性评估结果将其分为低、高风险,针对不同风险人群分别采用氟保护漆和氟化泡沫,证实氟化清漆和氟化泡沫对正畸不同龋易感人群龋白斑的防治效果。正畸医生在矫治治疗前对患者进行龋风险评估,进而为患者制定个性化分级防治策略,达到以一种经济、有效的方法降低早期龋白斑发生的目的。  

Objectives of Study:

According to the caries susceptibility assessment of orthodontic patients, they are classified as low and high risk, and fluoride varnish and fluoride foam are used for different risk groups to confirm the effectiveness of fluoride varnish and fluoride foam in the prevention and treatment of caries white spots in different caries susceptible groups in orthodontics. The orthodontist assesses the patient's caries risk before orthodontic treatment and then formulates a personalised classification strategy for the patient to reduce the occurrence of early caries white spots in an economical and effective way.

指标中文名:

牙釉质脱矿指数

指标类型:

主要指标

Outcome:

EDI

Type:

Primary indicator

测量时间点:

患者粘接托槽后每3个月,即分别于正畸开始后的3个月、6个月、9个月和12个月进行一次临床视诊评价和仪器检测,评价患者牙面釉质的脱矿程度。

测量方法:

评价符合纳入标准的受试者口腔健康状况,具体方法包括临床视诊评价和仪器评价这两种。临床视诊评价方法:将牙齿唇颊面以托槽为中心分为4个区域:龈方(g) 、切/方(o) 、近中(m) 、远中(d),分别记录4个区域的脱矿程度。0表示牙齿表面健康;1表示牙釉质早期视觉改变(釉质脱矿);2表示牙釉质明显视觉改变(釉质明显脱矿) ;3表示局限性牙釉质龋损(未累及牙本质) ;4表示潜行性牙本质龋损;5表示暴露

Measure time point of outcome:

The degree of demineralization of the patient's tooth enamel was evaluated by clinical visual evalua

Measure method:

The oral health status of the subjects who met the inclusion criteria was evaluated by two methods: clinical visualization and instrumental evaluation. Clinical visual evaluation method: The lip and cheek surfaces of the teeth were divided into 4 areas centered on the brackets: gingival (g), incisal (o), proximal-medial (m), and distal-medial (d), and the degree of demineralization was recorded for each of the 4 areas. 0 indicates healthy tooth surfaces; 1 indicates early visual changes in the e
