Use of "gelatamp" colloidal silver gelatin sponge to prevent dry socket after extracting mandibular impacted teeth

PURPOSE: To study the clinical effect of "gelatamp" colloidal silver gelatin sponge on preventing dry socket after extracting the mandibular impacted teeth.METHODS: 1350 teeth extracted from 976 patients who needed to extract the mandibular impacted teeth were divided into group A,group B and group C randomly."Gelatamp" colloidal silver gelatin sponge was implanted into alveolar socket after teeth extraction in group A,with absorbable gelatin sponge was implanted into alveolar socket in group B and nothing was implanted into alveolar socket in group C.The incidence of dry socket was observed,the data was analyzed using SPSS10.0 software package.RESULTS: The incidence of dry socket was 0.44% in group A,2% in group B and 4.44% in group C.There was significant difference in the incidence of dry socket between group A and group C(P0.01).There was also significant difference between group B and group C(P0.05) and between group A and group B(P0.05).CONCLUSIONS: The results demonstrate that "gelatamp" colloidal silver gelatin sponge can prevent the occurrence of dry socket after teeth extraction,which is of wide clinical use.
