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).
