After treatment, the clinical efficacies were evaluated, and GI scores, PLI scores, and BOP in two groups were compared. Results After treatment, the clinical efficacies in the control and treatment groups were 80.00% and 95.00%, respectively, and there was difference between two groups (P<0.05). After treatment, GI scores, PLI scores, and BOP in two groups were significantly decreased, and the difference was statistically significant in the same group (P<0.05). And the periodontal indexes in the treatment group were significantly lower than those in the control group, with significant difference between two groups (P<0.05). Conclusion Zhongtong'an Capsules combined with Cydiodine Buccal Tablets has clinical curative effect in treatment of gingivitis, can improve periodontal indexes of patients, with good safety, which has a certain clinical application value.
