Abstract

Objective

The aim of this study was to compare the effects of AFG and i-PRF on palatal wound healing and postoperative discomfort.

Materials and methods

Thirty-six patients in need of FGG were divided into three groups. AFG (n = 12) or i-PRF (n = 12) was applied and compared with control group (n = 12). Wound healing with H2O2 test, VAS, MSS, and LTH index were evaluated on the 3rd,7th, and 14th days and 1st month. The bleeding status was evaluated on the 3rd and 7th days. Palatal tissue thickness was measured at baseline, 1st month, and 3rd month.

Results

Epithelialization was higher in the test groups on the 14th day than the control group (p < 0.05). MSS scores at the 14th day and 1st month were lower in the AFG group than the control and the i-PRF group (p < 0.05). In the AFG group, LTH levels at the 3rd,7th, and 14th days and 1 month were higher than control and i-PRF groups (p < 0.05). VAS scores of the AFG group were lower than the control and i-PRF groups at the 7th day (p < 0.05). Bleeding was lower in the test groups than in the control group (p < 0.05). There was no difference between the groups in terms of tissue thickness (p > 0.05).

Conclusion

AFG and i-PRF have positive effects on the healing process by accelerating wound healing and reducing postoperative morbidity. Therewithal, AFG has superior properties in wound healing compared with i-PRF.

Clinical relevance

Patient discomfort and pain feeling have a great effect on patient’s tendency to surgery and platelet concentrates such as AFG and i-PRF overcome these problems and contribute to patient’s quality of life.
