干预措施:

对患牙进行窝沟封闭术治疗。具体步骤为:NSK低速马达弯头装锥形或清洁毛刷,在待封闭牙的窝沟点隙以低速旋转(< 350 转/分)的方式进行清洁,清洁 30 秒,注意清洁到牙齿窝沟点隙所在的各个牙面。清洁完成后用无油三用枪高压冲洗 20 秒,同时配合吸唾,使用尖探针清除窝沟中残余软垢和菌斑生物膜。棉卷隔湿,吹干。用小毛刷蘸取 35% 磷酸凝胶(Heraeus,GLUMA Etch 35)涂于窝沟点隙处,酸蚀范围可达牙尖斜面 2/3 ,酸蚀时间 30 秒。用大量流动的清水冲洗酸蚀部位20 秒钟以上,同时配合吸唾。冲洗吸唾后立即用干棉卷隔湿,用三用气枪吹干牙面。酸蚀牙面干燥后应呈白垩色,如无本现象应重新酸蚀、冲洗、干燥。用小毛刷蘸适量封闭剂(3M? ESPE? CLINPRO? 窝沟封闭剂)涂布在需要封闭的部位,使它充分流到窝沟、点隙内,可用涂布毛刷尖端指向窝沟点隙反复震动以排气泡。使用光固化灯固化(3M,Eliper),在光固化灯头距牙尖1mm处开启电源,不同牙面分别照射 20 秒。取出放置在受试者口内的隔湿棉球,可嘱咐受试者漱口。

干预措施代码:

Intervention:

Participants in the experimental group receive pit and fissure sealants treatment. Resin-based sealant clinical procedure: The surface of teeth is cleaned with a NSK low-speed motor elbow (< 350 rpm) equipped with a cleaning brush for 30 s. And high-pressure rinsing is carried out for 20 s accompanied by salivary suction, cotton rolls insolation and air-drying. Before sealant application, 35% phosphoric acid gel (Heraeus, GLUMA Etch 35) is applied to the fissure (the range was up to two-thirds of the cusp bevel) for 30 s. The etched area is rinsed with a water spray for 20 s, and then change the cotton rolls and dry with a gentle oil-free air flow until a uniformly spread chalky-white appearance is achieved. In case of no such phenomenon, it shall be etched, rinsed, and dried again as before. Sealant (3 M ESPETM CLINPROTM) is then applied to the pits and fissures using a disposable applicator and polymerized with a light curing lamp (3 M, Eliper) for 20 s, which has a 1470 mW/cm2 output and a diameter of 28 mm. This method of light curing is used in all the applications and the light intensity of the device is controlled regularly with a radiometer.

干预措施:

对患牙进行树脂充填术治疗。用球钻去除龋损组织,洞侧壁去除龋损组织直至坚硬牙本质,去除尖锐边缘,洞底保留韧状牙本质(用挖器刮除时有抵抗力)[39]。棉卷隔湿,加压无油空气吹干牙面,涂布树脂粘接剂(3M? Single Bond Universal Adhesive)20 秒,柔风吹匀 5 秒,光固化灯(3M,Eliper)光照 10 s,牙色流动树脂(3M ESPE Filtek? Z350XT Flowable Restorative)充填,光固化灯光照20s。取出放置在受试者口内的隔湿棉球。检查咬合高点,调牙合,抛光。可嘱咐受试者漱口。

干预措施代码:

Intervention:

Participants in the experimental group receive resin composite restoration treatment. Flowable resin composite clinical procedure: The caries tissue is removed with a small round bur (BR-49, IOS #001, diameter 0.6 mm, MANI), until only sound enamel and hard dentin remain at the cavity periphery, while centrally, firm dentin remains (resistant to scraping with a digger). Then, the exposed enamel is selectively acidetched by the same procedure that is used for the sealant group and leaving the dentin slightly moist. Subsequently, the resin adhesive (3 M Single Bond Universal Adhesive) is applied for 20 s, air-dried by gentle wind for 5 s. The light-curing lamp (3 M, Eliper) is lighted for 10 s, and the dental color flow resin (3 M ESPE Filtek? Z350XT Flowable Restorative) is dispensed carefully, avoiding air bubbles by using the needle provided by the manufacturer and polymerized with a light curing lamp for 20 s.

随机方法(请说明由何人用什么方法产生随机序列):

由统计专家使用Excel生成随机数列,按随机数从小到大排列,随机 数大小范围在前50%者分配至试验组,后50%者分配至对照组。

Randomization Procedure (please state who generates the random number sequence and by what method):

The randomization sequence was computer generated by an independent statistician. The subjects were allocated to two groups, experimental group and controlled group.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

接受试验的儿童和家长将不被告知采用的是哪种干预措施。统计者也不会被告知儿童是试验组或是对照组,也不能区分试验组和对照组。因为两种材料颜色的差异,随访的检查者可以区分受试儿童的分组。因此该试验为受试者盲及统计者盲的双盲实验。

Blinding:

It is a double-blind experiment with participants and statistician blinded. Treatments are performed at baseline by an independent dentist, who is not blinded due to the different application techniques of the materials, according to the manufacturer’s instructions.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

研究者根据受试者的原始病历,将数据及时、完整、正确、清晰地载入病例报告表中,每个入选病例必须完成病例报告表。数据管理所有过程均应按照其中定义的时间、内容及方法进行操作。所有完成的病例报告表由临床监查员审查后再移交统计单位进行数据分析。在数据审核并确认建立的数据库正确后,由数据管理人员、主要研究者、统计分析人员、申办者和监查管理人员共同对数据进行审核,并完成分析人群的最后定义及判断,之后由数据管理员对数据库进行锁定。锁定后的数据库或文件一般情况下不得再做改动。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

All data management processes should follow the defined timelines, content, and methods. Data are loaded into the case report form, which was required for each enrolled patient, based on the original medical records. All completed case report forms are reviewed by the monitor before being handed over to the statistician for data analysis. Once the established database is audited and confirmed to be accurate, data managers, principal investigators, statistical analysts, sponsors, and monitoring personnel jointly review the data and finalize the definition and criteria for the study population. Subsequently, the data administrator locks the database, and in general, no further modifications are allowed.
