Effect of Platelet-Rich Fibrin on Pain Following Closure of Oroantral Communication

Abstract

Background & aim: Oroantral communication (OAC) is an abnormal connection between the maxillary sinus and the oral cavity. It is mostly formed after the extraction of posterior maxillary teeth. Various methods for closure of communications have been reported in the literature. In this study, PRF plugs were used for immediate closure of OAC. The aim of this study was to compare the clinical results of PRF plugs with buccal advancement flap in the closure of oroantral communication.

Materials and Methods: Twenty-two patients aged 19-64 with oroantral communication were randomly divided into two groups. In group 1, OAC was treated with PRF plugs and in group 2 a buccal flap was used. Clinical follow up was carried at one week after surgery for assessment of success of surgery and pain.

Results: Four OAC recurred; three of them following buccal flap procedure with success rate 72.7% and one in PRF for a 90.9% success rate. The pain score was statistically greater in buccal flap group in First, second and third day following surgery.

Conclusions: The use of PRF in immediate closure of OACs is effective technique which enables the closure without a primary flap and makes the treatment of OACs less traumatic and easier. Moreover, this technique is cheap and easily accessible without the need for special surgical expertise
