Abstract:Objective To investigate the clinical efficacy of Qingwei power combined with Cefradine in the treatment of periodontal disease and effect on the plague index, periodontal pocket depth of probe sulcus bleeding index. Methods A total of 143 cases of patients who were enrolled by random number table were divided into observation group (n = 51), control group A (n = 46) and control group B (n =46). The observation group was treated with Qingwei power combined with Cefradine, the control group A was treated with Cefradine alone, and the control group B was treated with Qingwei power alone; all the three groups received treatment for 2 weeks. After treatment, plague index, periodontal pocket depth of probe, change of sulcus bleeding index, clinical efficacy and occurrence of adversereactions were compared among the three groups. Results In all the three groups, the plague index, the periodontal pocket depth of probe and the sulcus bleeding index after treatment were significantly lower than those before treatment (P < 0.05). After treatment, the plague index, the periodontal pocket depth of probe and the sulcus bleeding index in the observation group were significantly lower than those in the two control groups (P < 0.05); the plague index, the periodontal pocket depth of probe and the sulcus bleeding index in the control group A were significantly lower than those in the control group B (P < 0.05). The total efficiency of the observation group (96.07%) was significantly higher than that in both the control group A (80.44%) and the control group B (75.22%) with statistical difference (P < 0.05), and no adverse reaction was observed in any group. Conclusions The clinical efficacy of Qingwei power combined with Cefradine in the treatment of periodontal disease is significant, and could obviously decrease plague index, periodontal pocket depth of probe and sulcus bleeding index and improve the clinical symptoms, with important research significance.
