Randomized clinical studies were electronically and manually searched up until December 2023. Quantitative analyses were performed with the aim of evaluating the mean differences (MDs) between the treatment and control groups in terms of clinical attachment level (CAL) gain, probing pocket depth (PPD) reduction, gingival recession (GR), and radiographic bone gain (RBG) using random effect models. A total of seven studies were selected for the systematic review. Meta-analyses excluding studies with a high risk of bias highlighted a non-statistically significant result for the use of stem cells when compared to the control groups in terms of CAL gain [MD = 1.05; 95% CI (\u22120.88, 2.97) p = 0.29] and PPD reduction [MD = 1.32; 95% CI (\u22120.25, 2.88) p = 0.10]. The same also applied to GR [MD = \u22120.08; 95% CI (\u22120.79, 0.63) p = 0.83] and RBG [MD = 0.50; 95% CI (\u22120.88, 1.88) p = 0.48]. Based on the high heterogeneity, there is not enough evidence to consider the adjunctive application of orally derived mesenchymal stem cells as a preferential approach for periodontal regenerative treatment, as compared to standard procedures.<\/jats:p>","DOI":"10.3390\/dj12050145","type":"journal-article","created":{"date-parts":[[2024,5,16]],"date-time":"2024-05-16T03:24:48Z","timestamp":1715829888000},"page":"145","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Orally Derived Stem Cell-Based Therapy in Periodontal Regeneration: A Systematic Review and Meta-Analysis of Randomized Clinical Studies"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-1788-0714","authenticated-orcid":false,"given":"Alessandro","family":"Campagna","sequence":"first","affiliation":[{"name":"Department of Biomedical and Dental Sciences and Morphofunctional Imaging, University of Messina, 98122 Messina, Italy"},{"name":"Department of Surgical Sciences, C.I.R.
