Objective:To study the effect of periodontal non-surgical treatment on patients with periodontitis and pathological anterior tooth migration,and analyze the relationship between the severity of migration and the degree of repositioning after treatment,in order to provide a theoretical basis for the early prevention and treatment of patients with clinical pathological tooth migration.Methods:Twenty patients with periodontitis complaining of progressive enlargement and migration anterior space were collected from June 2021 to June 2022 at the Department of Dentistry,First Hospital of Shanxi Medical University.A total of 70 displaced dental spaces,divided into three groups according to the size of the displaced space: Group A: ≤1mm;Group B: 1.1~2mm;Group C: ≥2mm,periodontal primary therapy was completed,and the changes of displaced tooth space,periodontal Probing Depth(PD),gingival bleeding index(BI),clinical attachment level(CAL),alveolar bone absorption and translocation sagittal Angle were measured before treatment,three months and six months after treatment,and analyzed the above results statistically.Results:(1)Clinical periodontal indexes such as periodontal probing depth,attachment loss and bleeding index were significantly lower at three and six months after treatment compared to before treatment(P<0.05).(2)There were no significant difference in clinical indicators such as depth of probing,loss of attachment,bleeding index and height of alveolar bone between three months and six months after treatment(P>0.05).(3)There was no statistically significant difference between the changes in sagittal angle of displaced teeth three and six months after treatment and baseline(P>0.05)(4)At three months after treatment,55.71% of the displaced teeth were repositioned to different degrees,and at six months,the repositioning rate reached 72.86%.(5)Six months after treatment,only 52.78% of the three groups A,B and C had complete gap closure,while no complete gap closure was observed in group B and C.(6)Six months after treatment in groups A,B and C,the highest frequency of relocation was 80.56% in group A,68.18% in group B and 58.33% in group C.Conclusions:After non-surgical periodontal treatment,anterior teeth with displacement space ≤1mm can be closed.The smaller the displacement gap,the higher the frequency of repositioning after treatment.However,the long-term clinical effect needs further observation.Patients with large displacement space still need multidisciplinary treatment combined with orthodontics and restoration... |
