Objective To evaluate the clinical effect of enamel matrix derivative(EMD) assisted with connective tissue graft(CTG) in the treatment of gingival recession. Methods Search The Cochrane Library, PubMed, EMbase, Web of Science, Wanfang Public Database,VIP database and CNKI to search for randomized controlled trials of EMD in the treatment of gingival recession. The search period is from the establishment of the databases to October 3, 2022. The test group was treated with EMD+CTG, while the control group was treated with CTG alone. Meta-analyses were performed using Review Manager 5.4.1 and Stat12.0. Results Meta analysis results showed that only 12 months after treatment, there was a statistically significant difference in the PD and CAL outcome indicators between the EMD assisted treatment group and the control group [MDPD=-0.10, 95% CI (-0.19, -0.01), P = 0.03], [MDCAL=-0.38, 95% CI(-0.71, -0.04), P = 0.03]. There was no significant difference between the test group and the control group in other indicators. Conclusion EMD assisted CTG in the treatment of gingival recession may be beneficial to the reduction of PD and CAL. |
