Abstract

Aim

The aim of the present study was to assess the effectiveness of applying grape seed extract (GSE) gel in periodontal pockets for the treatment of chronic periodontitis.

Methods

Eighty-six sites with pocket depth (PD) >4 mm were selected from five systemically-healthy patients in whom scaling, and root planing were performed, and oral instructions were given, a week earlier. PD, gingival index (GI), plaque index (PI), and bleeding on probing (BOP) were measured, and sites were then divided into the control group (N = 38) and GSE group (N = 48). Four doses of formulated 2% mucoadhesive GSE gel were applied to GSE group sites at baseline visit (T0), and 3, 6, and 9 days after T0. Similarly, a control gel was applied to the control sites. PD, PI, GI and BOP were re-evaluated after 4 weeks and 6 months of first gel application.

Results

Paired t test for both the control and GSE groups showed a significant reduction for all variables after 6 months of gel application (P < .05). The independent t test showed a significant difference (P < .05) only in the reduction of gingival index (mean: 0.85 ± 0.77 for control and 1.3 ± 0.8 for GSE) and plaque index (mean: 0.75 ± 0.71 for control and 1.12 ± 0.7 for GSE).

Conclusion

The subgingival application of the formulated 2% mucoadhesive GSE gel showed significant improvement in the PI and GI only.
