  • 1Department of Periodontology, College of Dentistry, Seoul National University, Korea.


It has been reported that Magnoliae cortex extract has antibacterial and antimicrobial activity against pathogenic microbes and Zea Mays L. extract is effective for improving gingival tissue health. The purpose of this study was to examine the anti-inflammatory and antimicrobial effects of Zea Mays L. and Magnoliae cortex extract mixtures through experimental periodontitis induced beagle dog model. Nine beagle dogs with experimentally induced periodontitis were selected. Baseline clinical indices which includes plaque index, gingival index, probing pocket depth, clinical attachment level, gingival fluid flow rate were recorded and microbial assays were done. Magnoliae cortex and Zea Mays L., mixed at 2:1 ratio in 105mg capsular dosage, were taken by 3 capsule (Group I) or 6 capsule dosages (Group II) three times a day. After 4,8,12 weeks, clinical indices were recorded. All data of clinical indices were compared through one-way ANOVA with 95% confidence level. Clinical indices of group I and II showed significantly better results than those of control group. There were no significant differences between group I and II. In conclusion, it was confirmed that mixture of Magnoliae cortex and Zea Mays L. (mix ratio 2:1) possessed clinical improving effects to periodontitis.
