ABSTRACT
Objective: To assess the efficacy of platelet-rich fibrin (PRF) on the pain and healing of the
extraction socket related with established alveolar osteitis (dry socket, AO) after
the removal of maxillary and mandibular molars. Materials and Methods: One hundred consecutive adult patients with age group ranging from 18 to 40 years
along with established dry socket after maxillary and mandibular molar extractions
who have not received any treatment for the same were included in this single-arm
clinical trial. PRF was placed in the maxillary and mandibular molar extraction sockets
after adequate irrigation of the socket. All the patients evaluated for the various
study variables which include pain, degree of inflammation, and healthy granulation
tissue formation (wound healing) at the 1st, 3rd, 7th, and 14th post-PRF placement day in the alveolar socket. Data were analyzed using Shapiro-Wilk's
test, Chi-square test and/or Student's t-test, Friedman's test, Wilcoxon signed-rank
test, and Bonferroni test, with the significance level set at P < 0.05. Results: There was significant reduction in pain associated with AO at the 3rd and 7th post-PRF placement day in the extraction socket along with mark decrease in the degree
of inflammation at the 3rd post-PRF placement day, and there was better wound healing by the end of the 2nd week. Conclusion: The use of PRF in this clinical trial illustrates the promising results in terms
of reduced pain and better healing in the patients with sustained AO.
