Alveolar osteitis prevention by immediate placement of medicated packing.
OBJECTIVE
The purpose of this study was to evaluate whether immediate placement of medicated dry socket packing would decrease the incidence of alveolar osteitis (dry socket) with lower third molar extractions.


METHODS
In 100 patients, 200 lower third molars were extracted. One half of the sockets were packed to the crest of the alveolar ridge with a one-quarter-inch radiograph-detectable filament gauze that contained 9% eugenol, 36% balsam of Peru, and 55% petroleum jelly. The medicated packing was removed 1 week after surgery. None of the patients were taking antibiotics. Patients were instructed to increase their oral hygiene before and after surgery and were to use 0.12% chlorhexidine gluconate 2 days before and 3 days after surgery. RESULTS; Two hundred bilateral lower third molars of varying difficulty were extracted. The overall alveolar osteitis rate was 34 (17%). The immediately packed lower third molar sites had an alveolar osteitis rate of 8 (8%). The sockets that were not packed with medicated packing the day of surgery had an alveolar osteitis rate of 26 (26%). The difference was statistically significant (P =.001).


CONCLUSIONS
The results of this study suggest that placement of medicated dry socket packing immediately after lower third molar extraction decreases the alveolar osteitis rate.
