The aim of the study was to evaluate the effectiveness of platelet-rich fibrin (PRF)
for closer of oroantral communication (OAC) during two months of clinical and
radiographical follow-up. Eleven patients of both sexes(45.5% males ,54.5% females)
included in this study who had (OAC) after dental extraction. The closer was done by
using fibrin clot which was plugged into the alveolar socket of the extraction site that
contains the communication, and then we sutured the fibrin membrane to the gingival
borders above it. The results revealed that (PRF) can close the oroantral communication
successfully in 81.8% of the sample with the following complications :pain 27.3% , edema
18.2% , dehiscence 18.2%. We conclude that platelet-rich fibrin can close oroantral
communication that results from dental extraction when it has been used as a clot and
membrane together with simple complicated subsequent clinical symptoms and without
radiographical signs of inflammation of the maxillary sinus.
The aim of this study is to evaluate the combination of
autologous factors, platelet rich fibrin (PRF), with bone grafts,
beta tricalcium phosphate (βTCP), In Improving the Prognosis of
Surgical Treatment of periapical lesions .
This study was aimed to evaluate the effect of the use of Platelet-
Rich Fibrin on immediat complication following impacted
mandibular third molar surgery. forty extractions of bilateral
impacted mandibular third molars were performed in 20 volunt
eers
(18 to 25 years old). After extraction of right and left mandibular
third molars, the socket at 1 side received the autologous PRF (test
group) and the other was filled with blood clot (control group) .
