Oral hygiene habits formed during childhood are essential to long-term oral and general health. This study assessed how well various school-based oral health education strategies improved kids\u2019 oral hygiene, during the education and in long term. Controlled interventional studies involving healthy children in school settings were used in a quantitative systematic review and meta-analysis. Teachers, dental professionals, or other educational methods were used to deliver the educational programs. Standardized oral hygiene indices were used to compare the non-educated control groups before and after the intervention. Artificial intelligence\u2013assisted screening was used to improve the efficiency and consistency of the study selection process. While alternative educational approaches showed more limited effects, teacher-led and health care worker\u2013led interventions were linked to significant short-term improvements in oral hygiene. However, over longer follow-up periods, improvements were not consistently maintained. These results show how crucial schools are as venues for promoting oral health, but they also suggest that traditional education-focused interventions might not be enough to bring about long-lasting behavioral change. To achieve long-lasting population-level oral health benefits, program design, implementation, and integration into larger health promotion strategies may need to be strengthened.<\/jats:p>","DOI":"10.1177\/10901981261474902","type":"journal-article","created":{"date-parts":[[2026,8,18]],"date-time":"2026-08-18T10:32:47Z","timestamp":1787049167000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["The Positive Impact of School Dental Prevention Programs: A Systematic Review and Meta-Analysis"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-3598-8221","authenticated-orcid":false,"given":"Dalma","family":"T\u00e1bi","sequence":"first","affiliation":[{"name":"Semmelweis University, Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0148-4815","authenticated-orcid":false,"given":"\u00c9va","family":"Mlink\u00f3","sequence":"additional","affiliation":[{"name":"Semmelweis University, Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bianca","family":"Golzio Navarro Cavalcante","sequence":"additional","affiliation":[{"name":"Semmelweis University, Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eszter","family":"Uhrin","sequence":"additional","affiliation":[{"name":"Semmelweis University, Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2663-4912","authenticated-orcid":false,"given":"Rita","family":"Nagy","sequence":"additional","affiliation":[{"name":"Semmelweis University, Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bence","family":"Szab\u00f3","sequence":"additional","affiliation":[{"name":"Semmelweis University, Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P\u00e9ter","family":"Hegyi","sequence":"additional","affiliation":[{"name":"Semmelweis University, Budapest, Hungary"},{"name":"University of P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5506-8198","authenticated-orcid":false,"given":"G\u00e1bor","family":"Varga","sequence":"additional","affiliation":[{"name":"Semmelweis University, Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4714-1463","authenticated-orcid":false,"given":"Orsolya","family":"N\u00e9meth","sequence":"additional","affiliation":[{"name":"Semmelweis University, Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,8,18]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"crossref","unstructured":"Akera P.
