Abstract:

AIM: The aim of this study is to compare and evaluate the effectiveness of Advanced PRF(A-PRF) and Injectable PRF(I-PRF) in the healing process of the surgical sitesafterthe removal of mandibular third molars.Changes in pain, swelling, mouth opening was evaluated.   MATERIALS AND METHODS: 10 patients (3 males,7females ;18-35 years old) wereselected for the removal of bilateral impacted mandibular third molar teeth. A-PRF and I-PRF was placed in the right side for 5 patients in each group. In both the groups the left side of the patients was taken as the control group. Post-operative pain was evaluated using a visual analogue scale(VAS), postoperativeswelling was calculated using the distance between several facial landmarks(Carillo et al method) and mouth opening measured inter-incisally on the 1st postoperative day, 3rd day and the 7th day respectively. SPSS version 26.0 was used for data analysis.   RESULTS: Advanced PRF group recorded significant improvement in pain (p- value= 0.063),swelling (p-value =0.001)and mouth opening (p-value =0.013) compared to the Injectable PRF group. There was statistically significant difference between the advanced PRF and injectable PRF group.   CONCLUSION: Advanced PRF group showed decreasedpain, swelling and increased mouth opening compared to injectable PRF group.
