Assessing the Impact of Stem Cell-based Therapy on Periodontal Health: A Meta-analysis of Clinical Studies.
Objective: While clinical trials exploring stem cells for regenerating periodontal tissues have demonstrated positive results, there is a limited availability of systematic literature reviews on this subject. To gain a more comprehensive understanding of stem cell interventions in periodontal regeneration, this meta-analysis is undertaken to assess the beneficial effects of stem cells in human periodontal regeneration.
Methods: "PubMed," "Cochrane Library," "Web of Science," "Embase," "Wanfang," and "CNKI," were used to extract clinical studies related to the utilization of stem cells in repairing periodontal tissue defects. This search included studies published up until October 5, 2023. The inclusion criteria required the studies to compare the efficacy of stem cell-based therapy with stem cell-free therapy for regenerating periodontal tissues. Meta-analysis was conducted using Review Manager software (version 5.4).
Results: This meta-analysis synthesized findings from 15 selected studies investigating the impact of stem cell interventions on periodontal tissue regeneration. The "stem cell" group displayed a substantial reduction in clinical attachment level (CAL) compared to the "control" group within 3 to 12 months post-surgery. However, no significant differences in CAL gain were found between groups. Probing pocket depth (PPD) significantly decreased in the "stem cell" group compared to the "control" group, particularly for follow-up periods exceeding 6 months, and dental stem cell treatment exhibited notable improvements. Conversely, no significant differences were observed in PPD reduction. Gingival recession (GR) significantly decreased in the "stem cell" group compared to the "control" group at 3 to 12 months post-surgery. No significant differences were observed in GR reduction between groups. No significant differences were identified in cementoenamel junction-bone distance reduction, infrabony defect reduction, or bone mineral density increase between the two groups. Furthermore, no significant changes were observed in the gingival index, plaque index, or width of keratinized gingiva.
Conclusion: In conclusion, while stem cell-based therapy offers promising prospects for periodontal defect treatment, there are notable limitations in the current body of research. Larger, multicenter, double-blind RCTs with robust methodologies are needed to provide more reliable evidence for stem cell-based intervention in periodontitis.
