Abstract
Platelet concentrates (PCs) have been used for over 20 years in dentistry, as an adjunct to oral surgery procedures, to improve hard and soft tissue healing and control postoperative symptoms. Among various PCs, Leukocyte and Platelet-Rich Fibrin (L-PRF) has become very popular due to its excellent cost-effectiveness ratio, and to the simple preparation protocol, but comparative clinical studies with other PCs are lacking. The aim of this split-mouth cohort study was to evaluate the effect of Concentrated Growth Factors (CGF), a recently introduced PC, as compared to L-PRF for enhancing post-extraction socket healing. Methods: Patients in need of bilateral tooth extractions were included. Each side was treated with either CGF or L-PRF. Pain, socket closure and healing index were the main outcomes. Results: Forty-five patients (24 women), aged 60.52 ± 11.75 years (range 37–87 years) were treated. No significant difference in outcomes was found, except for Pain at day 1 (p < 0.001) and socket closure in the vestibulo-palatal/lingual dimension at day 7 post-extraction (p = 0.04), both in favor of CGF. Conclusions: based on the present results, CGF proved to be as effective and safe as L-PRF, representing a valid alternative option for improving alveolar socket healing and reducing postoperative discomfort.
Highlights
In dentistry, there has been increasing interest in products that promote wound healing
Platelets play a critical role in haemostasis, but are essential in the healing process as they are a source of growth factors [4]
The histograms showed a similarity of extraction site distribution between the two treatment groups
Summary
There has been increasing interest in products that promote wound healing. In this respect, in the last few years, the use of platelet preparations, alone or in combination with other biomaterials, has proven to be a valuable regenerative option [1,2,3]. In the last decade, it was shown that the use of autologous non-transfusional blood components in oral surgery allows for better and accelerated epithelialization and more vascularized connective tissue at wound healing sites, in addition to pain reduction [5,6,7,8,9,10].
