目的:评价非创伤性充填(ART)技术对恒牙窝沟封闭后,封闭剂保留及新生龋损发生情况。方法:1996年在四川省德阳市4所中学选取12～13岁儿童140名作191个牙ART封闭。采用WHO的ART标准器械,德国ESPE公司生产的高强度玻璃离子材料,对选择的牙面窝沟进行封闭;操作者为经中等口腔专业训练的医生。封闭后每年对ART封闭及牙龋损情况进行评价。结果:封闭后1、2、4、6年的完整保留率分别为75.4%、62.5%、50.0%、34.6%;成功率分别为89.6%、78.8%、68.5%、57.9%。试验后1年没有新生龋牙的发生,试验后2、3年,龋患发生率分别为1.6%、2.8%。试验后4年龋病有明显增加,试验4、5、6年后,龋病发生率分别为8.5%、16.1%、15.0%。结论:ART封闭试验3年的保存率较高、新生龋发生率低;试验6年封闭剂保留率虽然有所降低,但其结果还是令人满意的,预防龋病的效果是显著的。但封闭物脱落3年后,若没有重新修复,新龋患率大幅度上升,作为恒牙龋病防治的措施是适合和可接受的;是一种适合于在学校、社区开展的有效、实用的龋病预防方法。

Global and national policy frameworks emphasize the importance of people's participation and volunteers' role in disaster risk reduction. While research has extensively focused on volunteers in disaster response and recovery, less attention has been paid on how organizations involved in disaster risk management can support volunteers in leading and coordinating communitybased disaster risk reduction. In 2019, the New Zealand Red cross piloted the Good and Ready initiative in Auckland,Aotearoa New Zealand, with the objective to empower local people in resilience building with a focus on volunteers and community participation. This research examined the positive and negative outcomes of Good and Ready and investigated volunteers' experiences in the disaster resilience initiative. It involved the codesign of a questionnaire-based survey using participatory methods with Good and Ready volunteers, the dissemination of the survey to gather volunteers' viewpoints, and a focus group discussion with participatory activities with Red cross volunteers. The findings highlight that a key challenge lies in finding a balance between a program that provides flexibility to address contextual issues and fosters communities' ownership, versus a prescriptive and standardized approach that leaves little room for creativity and self-initiative. It pinpoints that supporting volunteers with technical training is critical but that soft skills training such as coordinating, communicating,or facilitating activities at the local level are needed. It concludes that the sustainability of Good and Ready requires understanding and meeting volunteers' motivations and expectations and that enhancing partnerships with local emergency management agencies would strengthen the program.
