This study examined whether the moisture control innovation (tongue and cheek retractors and saliva contamination (SS-suction)) used without dental assistance could improve the quality of dental sealant in rural Thai school children compared to a standard treatment, i.e., high power suction with dental assistance. A single blind, cluster randomized controlled trial was conducted. Participants were 15 dental nurses working in sub-district health promoting hospitals and 482 children. All dental nurses attended workshops of SS-suction and revised dental sealant procedures. Children with sound lower first permanent molar teeth were simple-randomly assigned to either an intervention or control group. The children in the intervention group were sealed with SS-suction, and the children in the control group were sealed with high power suction and dental assistance. There were 244 children in the intervention group and 238 children in the control group. Dental nurses' satisfaction on SS-suction was record by visual analogue scale (VAS) for each tooth during treatment. After 15-18 months, caries on sealed surfaces were examined. The results showed that the median satisfaction score of SS-suction was 9 out of 10, and 17-18% children experienced uncomfortable sensation during insertion or removal. The uncomfortable feeling disappeared once the suction was in place. Caries on sealed surfaces did not differ significantly between the intervention and control groups. Caries on the occlusal surface was present in 26.7% and 27.5%, and caries on the buccal surface was present in 35.2% and 36.4% of cases in the intervention and control groups, respectively. In conclusion, dental nurses were satisfied with SS-suction in terms of both function and safety. The effectiveness of SS-suction was compatible with the standard procedure after 15-18 months.
本研究旨在探讨在没有牙科协助的情况下使用潮气控制创新（颊舌牵开器和唾液污染（SS-抽吸））是否可以提高泰国农村学童牙科密封剂的质量，与标准治疗相比，即使用牙科协助的高功率抽吸。进行了一项单盲、整群随机对照试验。参与者为在区卫生促进医院工作的 15 名牙科护士和 482 名儿童。所有的牙科护士都参加了 SS-抽吸和修改后的牙科密封剂程序的研讨会。具有健康的下颌第一恒磨牙的儿童被简单随机分配到干预组或对照组。干预组的儿童使用 SS-抽吸进行密封，对照组的儿童使用高功率抽吸和牙科协助进行密封。干预组有 244 名儿童，对照组有 238 名儿童。在治疗过程中，牙科护士使用视觉模拟量表（VAS）记录 SS-抽吸对每颗牙齿的满意度。15-18 个月后，检查密封表面的龋齿情况。结果显示，SS-抽吸的中位数满意度评分为 10 分中的 9 分，17-18%的儿童在插入或取出时感到不适。一旦抽吸到位，不适感就会消失。密封表面的龋齿在干预组和对照组之间没有显著差异。在干预组和对照组中，窝沟面的龋齿分别为 26.7%和 27.5%，颊面的龋齿分别为 35.2%和 36.4%。总之，牙科护士对 SS-抽吸的功能和安全性都很满意。15-18 个月后，SS-抽吸的效果与标准程序相当。
