Effect of povidine iodine gelation sponge on the incidence of dry socket caused by impacted mandibular third molar extraction

Objective:To explore effects of povdine idione gelatin sponge on the prevention of dry socket caused by impacted mandibular third molar extraction.Method:impacted mandibular third molars extracted were divided into two groups at random.One was the experimental group,in which we implanted povdine idione gelatin sponge into alveolar nest,cotton bale staying for 30 min;the other was contrast group,in which we didn't implant anything into alveolar nest,only cotton bale staying for 30 min.Then we compared occurrence of dry socket of the two groups.Result:There were 6 persons infected with dry socket in the contrast group,with the incidence rate of 5.66%,while there was only one infected with dry socket in the experimental group,the incidence being 0.85%.Suggesting that the incidence of dry socket was significantly lower in the experimental group compared with contrast one.Conclusion:The result demonstrates that the povdine idione gelatin sponge can prevent the occurrence of dry socket.
