This systematic review and meta-analysis aimed to evaluate the current evidence about the changes in GT and KTW following the injection of injectable platelet-rich fibrin (i-PRF) in patients with thin GP.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;A thorough search was conducted up to April 2024 across the following nine databases: The Cochrane Central Register of Controlled Trials (CENTRAL), PubMed&lt;sup&gt;®&lt;/sup&gt;, Scopus&lt;sup&gt;®&lt;/sup&gt;, Web of Science&lt;sup&gt;®&lt;/sup&gt;, Google Scholar, Trip, CINAHL via EBSCO, EMBASE via OVID, and ProQuest. This review covered parallel-group and split-mouth randomized controlled trials (RCTs) which investigated the changes in GT and KTW following i-PRF injection on the buccal anterior region in both jaws for individuals with thin GP. The risk of bias in the included studies was evaluated using Cochrane's tool (RoB 2), and the GRADE framework was utilized to assess the overall strength of evidence. Agreement between the authors was assessed using Cohen's kappa statistic.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Seven RCTs were included in this review, five of which were appropriate for the quantitative synthesis of data. The meta-analysis showed a statistically significant increase in the GT in the i-PRF group at all assessment times compared to baseline (MD ranged from 0.12 mm to 0.38 mm). Regarding KTW, 4-time injections led to a significant increase in KTW after 3-month and 6-month follow-ups compared to baseline (MD = 0.31 mm, and MD = 0.37 mm, respectively). In contrast, 3-time injections yielded a non-significant increase in KTW after 1 and 3 months of follow-up (MD = 0.14 mm at both assessment times). The strength of evidence supporting these findings ranged from low to moderate.
