Efficacy evaluation of subgingival scaling with Bushenguchiwan in short-term treatment of moderate to severe periodontitis

Objective:To evaluate the effect of subgingival scaling with Bushenguchiwan on short-term treatment of moderate to severe periodontitis.Method:44 moderate to severe periodontitis patients were enrolled into this trial,whom were randomly divided into two groups,23 in the experimental group and 21 in the control group.Each patient with 2 index teeth were selected.Every patient in this study was given periodontal initial therapy,including supragingival scaling and subgingival scaling.After that,patients in the experimental group took 4 g Bushenguchiwan orally twice a day for 3 months.Bleeding on probing(BOP),probing depth(PD),attachment loss(AL)and mean grey values(MGVs) of the alveolar bone of all teeth which were selected were measured before and after treatment.Result:After 3 months treatment,the ratio of BOP(+),PD and AL in the experimental group were decreased significantly(P 0.05),while MGVs were significantly increased(P 0.05).The ratio of BOP(+) and PD in the control group showed the same change as in the experimental group.However,AL and MGVs in the control group showed positive change(P 0.05).The total efficacy ratio of the experimental group was higher than that of the control group,with significantly difference(P 0.05).Conclusion:The effect of subgingival scaling with Bushenguchiwan on short-term treatment of moderate to severe periodontitis is obviously superior to simple scaling.The effect may be associated with Bushenguchiwan which could promote alveolar bone formation and decrease AL.
