As an alternative to conventional antifungal drugs, the use of biofilm-modulating strategies, such as probiotic bacteria, may be a sustainable option. Probiotics are live microorganisms that have beneficial health effects, while prebiotics are compounds in food that foster the growth or activity of the beneficial microorganisms. The aim of this paper was to review current clinical findings regarding the antifungal effects of pre- and probiotic supplements, including syn- and postbiotics, in children. Methods: We searched two databases (PubMed and Google Scholar) for controlled clinical trials published in English up to 20 April 2025, and two authors scanned the abstracts independently for relevance. The selected full-text papers were reviewed and assessed for risk of bias. Results: Four articles published between 2013 and 2025 were included in this review, covering a total number of 208 caries-active children between 3 and 14 years of age. Study designs were heterogeneous, and we observed conflicting results: two studies with probiotic streptococci failed to demonstrate any beneficial effects on the counts of salivary C. albicans, while interventions with L. plantarum and L. rhamnosus significantly reduced C. albicans compared with controls. None of the included reports displayed a low risk of bias. No clinical studies utilizing prebiotics, synbiotics, or postbiotics were retrieved. Conclusions: We found insufficient evidence concerning the antifungal effects of probiotic supplements in children. Therefore, we recommend future clinical trials to explore the ability of pre-, pro-, and postbiotic interventions to affect cross-kingdom biofilms in order to support a balanced and health-associated composition of the dental biofilm in children.<\/jats:p>","DOI":"10.3390\/nu17142253","type":"journal-article","created":{"date-parts":[[2025,7,8]],"date-time":"2025-07-08T02:25:53Z","timestamp":1751941553000},"page":"2253","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Probiotics, Prebiotics, Synbiotics, and Postbiotics Against Oral Candida in Children: A Review of Clinical Trials"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0248-6625","authenticated-orcid":false,"given":"Anna","family":"Turska-Szybka","sequence":"first","affiliation":[{"name":"Department of Paediatric Dentistry, Medical University of Warsaw, \u017bwirki i Wigury St. 61, 02-091 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dorota","family":"Olczak-Kowalczyk","sequence":"additional","affiliation":[{"name":"Department of Paediatric Dentistry, Medical University of Warsaw, \u017bwirki i Wigury St. 61, 02-091 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0199-9210","authenticated-orcid":false,"given":"Svante","family":"Twetman","sequence":"additional","affiliation":[{"name":"Department of Odontology, Faculty of Health and Medical Sciences, University of Copenhagen, Denmark N\u00f8rre All\u00e9 20, 2200 Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"GBD 2017 Oral Disorders Collaborators, Bernabe, E., Marcenes, W., Hernandez, C.R., Bailey, J., Abreu, L.G., Alipour, V., Amini, S., Arabloo, J., and Arefi, Z.
