Analysis of the effect of bracketless invisible orthodontic treatment combined with initial periodontal therapy on oral health and inflammatory response in patients with anterior tooth fan-displacement caused by periodontal disease
Objective To analyze the effect of bracketless invisible orthodontic treatment combined with initial periodontal therapy on oral health and inflammatory response in patients with anterior tooth fan-displacement caused by periodontal disease,so as to provide reference for clinical treatment of anterior tooth fan-displacement caused by periodontal disease.Methods 60 patients with anterior tooth fan-displacement caused by periodontal disease were selected as observation samples and divided into a control group and an observation group according to computer grouping method,with 30 cases in each group.The control group was given periodontal splint fixation combined with periodontal basic treatment,and the observation group was given bracketless invisible orthodontic treatment combined with initial periodontal therapy.The periodontal indicators,oral health,indicators of inflammation and dental function were compared between the two groups before and after treatment.Results Before treatment,there were no differences in periodontal pocket depth,alveolar bone height,dental coverage distance and gingival sulcus bleeding index between the two groups(P>0.05).After treatment,the periodontal pocket depth in the observation group was(2.65±0.51)mm,the dental coverage distance was(1.78±0.25)mm,and the gingival sulcus bleeding index was(1.56±0.42)points,which were significantly lower than(4.73±0.62)mm,(3.19±0.35)mm,and(3.07±0.30)points in the control group;the alveolar bone height of(5.71±0.29)mm in the observation group was higher than(5.55±0.20)mm in the control group(P<0.05).Before treatment,there were no differences in the scores of independent ability,psychological discomfort,pain and discomfort,and functional limitation between the two groups(P>0.05).After treatment,the scores of independent ability in the observation group was(1.86±0.31)points,the scores of psychological discomfort was(1.63±0.21)points,the scores of pain and discomfort was(1.86±0.19)points and the scores of functional limitation was(1.58±0.20)points,which were significantly lower than(2.16±0.40),(2.07±0.38),(2.33±0.30)and(2.17±0.15)points in the control group(P<0.05).Before treatment,the levels of C-reactive protein(CRP),interleukin-1β(IL-1β)and interleukin-6(IL-6)were not different between the two groups(P>0.05).After treatment,the observation group had CRP of(4.32±0.30)mg/L,IL-1β of(167.26±19.32)pg/ml,and IL-6 of(8.75±1.80)pg/ml,which were significantly lower than(5.20±0.41)mg/L,(210.38±17.95)pg/ml,and(10.34±1.23)pg/ml in the control group(P<0.05).Before treatment,there were no differences in the scores of tooth color,tooth shape,marginal fitness and occlusal relation between the two groups(P>0.05).After treatment,the scores of tooth color,tooth shape,marginal fitness and occlusal relation in the observation group were(6.82±0.46),(7.12±0.50),(7.81±0.34)and(7.68±0.22)points,which were significantly higher than(5.63±0.37),(5.69±0.38),(6.19±0.24),and(6.10±0.33)points in the control group(P<0.05).Conclusion The combination of bracketless invisible orthodontic treatment and initial periodontal therapy provides a more comfortable orthodontic method for patients with anterior tooth fan-displacement caused by periodontal disease.It can not only reduce the inflammatory response,but also help to correct the teeth more efficiently and accurately,and helps to restore the patient's oral health to a normal state.
