This scoping review aims to explore researchers’ explanations for the success of interventions promoting oral health in young children (≤5 years) and their families living in vulnerable circumstances in Western countries to strengthen future interventions. A comprehensive search strategy was developed and applied to three electronic databases: PubMed, Embase.com, and Clarivate Analytics/Web of Science Core Collection.

In particular, interventions implemented at the macro level (n = 1), macro-meso levels (n = 4) and macro-meso-micro levels (n = 10) seem to be the most promising. The researchers argue that interventions with a personalised, educational and culturally sensitive approach, delivered through interdisciplinary collaboration between professionals within and outside the dental sector, supported by adequate resources (e.g., appropriate time, funding, location), are key to success. Future interventions require a careful account of families' complex daily realities by intensifying collaboration between parents, community workers, school staff, dental professionals, primary care providers and government, providing training and balanced workloads for professionals and ensuring sufficient resources. According to the researchers, engaging with actors from macro, meso, and micro system levels is essential in child oral health promotion.

However, in their analyses, the 13 studies used varying definitions of failure and did not account for some important factors that might have influenced restoration failures. Future reviews need to account for other influential variables that contributed to restoration failures.</div></div>","PeriodicalId":13785,"journal":{"name":"International dental journal","volume":"75 4","pages":"Article 100871"},"PeriodicalIF":3.2,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144480204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to assess the available evidence concerning AI-powered PBL/CBL on students’ knowledge acquisition, clinical reasoning capability and satisfaction.</div></div><div><h3>Methods</h3><div>An electronic search was carried out on PubMed, MEDLINE, the Cochrane Central Register of Controlled Trials and Web of Science. Clinical trials published in English with full text available, which implemented AI technologies in PBL/CBL in the medical/dental field and evaluated knowledge acquisition, clinical reasoning and/or satisfaction were included. The quality assessment was conducted using RoB 2 by two calibrated assessors. Data synthesis and meta-analysis were performed, the standardised mean difference (SMD) or standardised mean (SM) and 95% confidence intervals (CIs) were calculated, and heterogeneity was quantified.</div></div><div><h3>Results</h3><div>Six randomized controlled trials were included, with an overall risk of bias judged to have ‘some concerns’. For knowledge acquisition, 4 studies were included in the meta-analysis. A low heterogeneity (I² = 20%) was detected and a fixed-effect model was utilised. Compared with the control group, the AI intervention significantly improved knowledge acquisition by 46% (95% Cls [0.18-0.73], <em>P</em> = .001). For clinical reasoning capability, due to methodological and measurement heterogeneity among studies, statistical analysis was not feasible. Three studies were selected for the meta-analysis of students’ satisfaction. Heterogeneity was moderate (I² = 32%), and a generic inverse variance method was selected. The pooled SM score was 0.7 (95% Cls [0.47-0.92]), and the overall effect was statistically significant (<em>P</em> &lt; .00001).</div></div><div><h3>Conclusion</h3><div>Despite limitations such as the limited number of included studies and the overall risk of bias concerns, AI-powered PBL/CBL has the potential to enhance students’ knowledge acquisition and learner satisfaction compared to traditional learning approaches.</div></div><div><h3>Clinical Relevance</h3><div>Not applicable.</div></div>","PeriodicalId":13785,"journal":{"name":"International dental journal","volume":"75 4","pages":"Article 100858"},"PeriodicalIF":3.2,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144491633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
