Effects of orthodontic treatment on tooth coverage distance and periodontal pocket depth in patients with anterior teeth displacement caused by periodontal disease
Objective To investigate the effects of orthodontic treatment on tooth coverage distance and periodontal pocket depth in patients with anterior teeth displacement caused by periodontal disease.Methods A total of 100 patients with anterior teeth displacement caused by periodontal disease admitted in our hospital from January 2020 to January 2022 were selected as the research objects.According to the random number table method,the patients were divided into control group(n=50)and observation group(n=50).Both groups received conventional periodontal disease treatment,the control group was treated with conventional periodontal splint fixation,and the observation group was treated with orthodontic treatment.The clinical efficacy,periodontal indicators,periodontal index and chewing function were compared between the two groups.Results The total effective rate of treatment in the observation group was 96.00％,which was higher than 84.00％in the control group,and the difference was statistically significant(P＜0.05).Before treatment,there were no significant differences in periodontal pocket depth,alveolar bone height and tooth coverage distance between the two groups(P＞0.05);after treatment,the periodontal pocket depth and tooth coverage distance of the two groups were smaller than those before treatment,the alveolar bone height was greater than that before treatment,those of the observation group were better than the control group,and the differences were statistically significant(P＜0.05).Before treatment,there were no significant differences in probing depth(PD),sulcus bleeding index(SBI)and gingival index(GI)scores between the two groups(P＞0.05);after treatment,the PD,SBI and GI scores of the two groups were lower than those before treatment,those of the observation group were lower than the control group,and the differences were statistically significant(P＜0.05).Before treatment,there were no significant differences in masticatory efficiency and bite force between the two groups(P＞0.05);after treatment,the masticatory efficiency and bite force of the two groups were higher than those before treatment,those of the observation group were higher than the control group,and the differences were statistically significant(P＜0.05).Conclusion Orthodontic treatment can improve the periodontal index and chewing function of patients with anterior teeth displacement caused by periodontal disease,and the treatment effect is significant.
