Abstract：
Disadvantaged schoolchildren from rural and low socioeconomic backgrounds face persistent oral health inequalities, specifically dental caries, and periodontal diseases. This protocol aims to review the effectiveness of promotive and preventive oral health interventions for improving the oral health of primary schoolchildren in these areas. We will search the PubMed, MEDLINE, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) via EBSCOhost, Cochrane Library, Web of Science, Dentistry and Oral Sciences databases for studies published from 2000-2023. The review includes randomised/nonrandomised controlled trials and community trials evaluating the effectiveness of promotive and preventive oral health interventions on at least one of these outcomes: changes in dental caries status, periodontal disease status, oral hygiene status/practices, sugar consumption, or smoking behaviours. Two reviewers will independently assess the searched articles, extract the data, and assess the risk of bias in the studies using the Cochrane Risk of Bias 2 (ROB 2) for randomised controlled trials and Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I) for non-randomised controlled trials. Both narrative and quantitative analyses will be conducted. However, only narrative synthesis will be performed if the data are substantially heterogeneous. The synthesised evidence from this review can inform policymakers on evidence-based interventions to improve the oral health outcomes of schoolchildren from rural and low socioeconomic backgrounds. Systematic Review Registration PROSPERO (Registration number: CRD42022344898).
摘要：
来自农村和低社会经济背景的弱势学童面临持续的口腔健康不平等，特别是龋齿，和牙周疾病。该协议旨在审查促进和预防口腔健康干预措施对改善这些地区小学生口腔健康的有效性。我们将搜索PubMed,MEDLINE,和通过EBSCOhost的护理和相关健康文献累积指数（CINAHL），科克伦图书馆,WebofScience,2000-2023年发表的牙科和口腔科学研究数据库。该综述包括随机/非随机对照试验和社区试验，评估促进和预防性口腔健康干预措施对至少一个结果的有效性：龋齿状态的变化，牙周病状况，口腔卫生状况/实践，糖消耗,或吸烟行为。两名审稿人将独立评估搜索到的文章，提取数据，在随机对照试验中使用Cochrane偏差风险2(ROB2)和非随机对照试验中使用非随机干预研究中的偏差风险(ROBINS-I)评估研究中的偏差风险。将进行叙述和定量分析。然而,如果数据基本上是异质的，则仅进行叙述性合成。这篇综述的综合证据可以为决策者提供基于证据的干预措施，以改善来自农村和低社会经济背景的学童的口腔健康结果。系统审查注册PROSPERO（注册编号：CRD42022344898）。
