Effect of the emodin thermosensitive hydrogel on coilagenase in gingival crevicular fluid of patients with chronic periodontitis / 中国基层医药

ABSTRACT

Objective To observe the effect of the emodin thermosensitive hydrogel on collagenase in gingival crevicular fluid of patients with chronic periodontitis and to evaluate the clinical efficacy.Methods Forty patients with chronic periodontitis were selected.For each patient after scaring and root planning,the one teeth on one side in a person was assigned at the test group and treated with the emodin thermosensitive hydrogel in the pocket once a week for four weeks.The teeth on the other side were assigned as the control group,just with the primary periodontal treatment.The PLI、SBI、PD、AL、MD and content of collagenase in gingival crevicular fluid were examined at baseline,before administration and after administration four weeks.The COL-II level in GCF was detected using ELISA method.Results There were no significant differences in PLI、SBI、PD、AL、MD and content of collagenase in gingival crevicular fluid before the treatment(P ＞ 0.05).While there are some evidences that periodontal indexes dropped down and the type Ⅱ collagenase level in gingival crevicular fluid also declined after using the emodin thermosensitive hydrogel than the control group(t =3.46,4.02,4.18,3.03,2.79,4.29,all P ＜ 0.05).Conclusion Ultrasonic scaling using the emodin thermosensitive hydrogelas was more effective in reducing the type Ⅱ collagenase level in gingival crevicular fluid.And improving clinical parameters associated with periodontal health in patients with chronic periodontitis.
