Đánh giá kết quả đau, sưng, dị cảm và khít hàm bằng phương pháp phẫu thuật răng khôn hàm dưới kết hợp màng fibrin giàu tiểu cầu PRF (platelet-rich-fibrin)

Determining the role of platelet-rich fibrin membrane PRF (Platelet-rich-fibrin) in the surgical treatment of lower third molar to help stop bleeding, reduce swelling and pain, stimulate rapid wound healing, and increase the ability to create bone, reducing the rate of alveolar osteomyelitis of patients who come for surgical treatment of lower third molar at Cai Nuoc General Hospital. Materials and methods: Convenient sampling of 99 patients aged 18 years and older who came for surgical treatment of lower third molar with platelet-rich fibrin membrane PRF (Platelet-rich-fibrin) at Cai Nuoc General Hospital from March 2019 to May 2020. Results: Wound healing: The incisions after 1 day of tooth extraction mostly healed well (79.8%), after 3 days mostly healed well (60.6%). Swelling: Rate Less swelling accounted for the same rate at 1 day and 3 days after surgery (57.6%) and only 4% at 7 days. Severe swelling decreased from 35.4% at 1 day to 25.3% at 3 days and 3% at 7 days. Pain sensation: On the 1st day, 66.7% of patients had little pain, 30.3% of moderate pain and 3% is very painful. On the 3rd day, 72.7% had little pain. On the 7th day, only 3% of the patients still felt little pain. Opening the mouth: on the 1st day, 50.5% opened the mouth well, on the 3rd day, 65.7% opened the mouth well, on the 7th day there was 99.0 % of patients opened their mouth well and 100% opened their mouth well at 1 month. Conclusion: Platelet-rich-fibrin membrane PRF (Platelet-rich-fibrin) has a role in supporting the surgical treatment of lower third molar.
