Objectives In our research, we evaluated the effect of coconut and sesame oils using the microneedling technique on gingival inflammation and plaque accumulation among patients with gingivitis by creating microholes in the gingiva to facilitate the concentration and entrance of the oils through gingival tissues. Materials and Methods Twenty‐four patients with clinically diagnosed plaque‐induced gingivitis were selected from Vision dental hospital, Riyadh, KSA, and assigned to one of three groups randomly; group A consisted of eight participants who were treated with dermapen and topical coconut oil, group B had eight participants who were treated with dermapen and topical sesame oil, and group C involved eight patients who received periodontal mechanical treatment only. Postintervention gingival status and plaque status for all participants were assessed using a modified average gingival index and a plaque index at Weeks 1, 2, and 4. Results Groups A and B experienced highly significant reductions in gingival indices, while group C showed reduced scores but was not significantly notable. On the contrary, the three studied groups exhibited no significant difference in the reduction of plaque indices when compared altogether. Conclusion Our study demonstrated an effective novel technique that revealed a noticeable improvement in gingival status and a reduction in the average gingival index and plaque index.
