Aim: The present study aimed to assess the efficacy of combining microneedling (MN) and injectable platelet-rich fibrin (i-PRF) administration with i-PRF alone in augmenting the thickness of gingiva to manage thin periodontal phenotype. Methodology: The clinical trial involved 36 patients who were diagnosed with thin periodontal phenotype. They were randomized under two groups: MN + i-PRF versus i-PRF alone, carried out as a split-mouth trial. One quadrant was treated only with i-PRF delivery through the gingival sulcus, while the contralateral side was treated with MN and i-PRF in 3 sessions at 10-day intervals. The primary parameter measured was the thickness of the gingiva, at baseline and 3 months following therapy. Statistical analysis was performed using the Mann-Whitney U test. Wilcoxon’s signed ranking test for inter-group and intra-group analysis, respectively. Results: The study results showed a significantly greater increase in gingival thickness (GT) in sites where both MN and i-PRF injection was done, compared to i-PRF alone, with a p value of .04. Conclusion: Both treatment modalities showed improvement in GT, being a minimally invasive alternative for mucogingival surgery. Adjunctive MN was found to be more beneficial than i-PRF alone. However, further research should be carried out to address the drawbacks of the study and for a better understanding of this novel approach.
