Antifibrinolytic prevention of alveolitis sicca dolorosa

In a double-blind study dental cones containing the antifibrinolytically active propylic ester of p-hydroxybenzoic acid (PEPH), sulfanilamide and sulfathiazol or placebo were placed in dental sockets following removal of impacted mandibular third molars on 95 consecutive patients, 50 women and 45 men. The duration of the operation, the type of surgeon, preoperative symptoms and the use of peroral anticonception were recorded. The patients were asked to return to the clinic on the seventh postoperative day, and it was then noted whether the healing was disturbed by Alveolitis Sicca Dolorosa (ASD) or not. Statistical analysis showed a significantly prophylactic effect of PEPH against ASD. The prophylactic effect was most pronounced in the group of male patients without preoperative symptoms and in the group of patients operated by dental students. It could not be demonstrated that the sulfa drugs in the cones were of any benefit to the healing of the socket.
