The Clinic And Experiment Research Of Preventing Dry Socket By Local Applied Drugs

OBJECTIVE The purpose of the study is compared with the differences in the rate of bacteria related to dry socket found between 94 patients' mandibular impacted teeth removed after their periconorals were rinsed with hydrogen peroxide solution and iodophenol was applied, and commonly removed teeth, an efficient, economical method for preventing from alveolar osteitis will be found. PATIENTS AND. METHOD 94 patients are chosen and divided into three groups according to a certain standard: Group A (33 patients' periconorals rinsed with 3% hydrogen peroxide solution and applied with iodophenol); Group B (31 patients' periconorals rinsed with 3% hydrogen peroxide solution); Group C (30 patients' periconorals controlled). The bacteria in the sack are collected for aerobic and anaerobic cultures. RESULTS Bacteroides melaninogenicus attached to the patients' periconorals in Group A found is 33.3% before the operation and 10. 1% after the operations; The rate of bacteroides melaninogenicus found on patients' periconorals in Group B is 32.3% and 16.1% before and after the operation; The rate of bacteroides melaninogenicus found on the patients' periconorals in Group C is 30. 0% and 33. 3% before and after the operation. The rate of streptococcus found on the patients' periconorals of the three groups is 100% respectively before and after the operation. CONCLUSION The dry socket is greatly decreased when mandibular impacted teeth are removed by rinsed periconorals with 3% hydrogen peroxide solution and applying iodophenol. This method is easy , efficient and economical and great value available.
