Abstract
Aim: A clinical trial to determine the post-operative outcomes of a PRF-treated socket versus
a conventionally treated socket following surgical removal of third molar teeth.
Introduction: Third molar surgery is a procedure many have to endure and which often results
in prolonged healing time with consequential absence from work and school. This has
motivated clinicians to seek methods to enhance the healing process and in effect, reduce the
healing time. Research on the use of PRF in enhancing wound healing in maxillofacial and oral
surgery have shown varying results. Therefore, this study was conceived to ascertain the effect
PRF has on the post-operative sequelae of third molar teeth.
Materials and Methods: This was a split mouth, prospective, single blinded, randomized
control trial. The study sample was made up of 26 patients (N=26) who met the inclusion
criteria. Four of the patients experienced neurosensory fallout of an associated nerve and were
subsequently excluded from the sample. This resulted in the total sample size of twenty-two
patients (n=22). Symmetrically impacted maxillary and mandibular third molars were removed
under general anaesthesia. Patients were treated in a within subject design: when one side of a
patient was treated with PRF, the other side was conventionally treated and acted as a control.
The allocation of the side treated with PRF was 'random'. Patients were followed-up on Day 2
and Day 7, respectively. Pain scores were recorded on a visual analogue scale (VAS) using 0
to 10 pain score. Swelling, wound dehiscence, development of alveolar osteitis, wound
infection and post-operative bleeding were compared between the intervention and control
side.
Results: Twenty-two patients (females = 13 and males = nine) b
