The effect of periodontal treatment on the basis of analysis of orthodontictreatment in patients with periodontal disease

摘要

Objective: To find out the effect of periodontal treatment on orthodontic treatment. Methods: A total of 30 cases from January 2013 to November 2014 were taken into the research. The periodontal health indicators (probing depth/PD, tooth mobility/TM, bleeding on probing/BOP, and clinic attachment loss/CAL) were taken into measurements, before any treatment T0, after 3-month periodontal treatment T1 and after the periodontal treatment combined with orthodontic treatment T2, respectively. Also, the changes of the distance from alveolar ridge crest to cement-enamel junction (CEJ), root length and density of alveolar bone were observed through CBCT measurement. Results: The TM in T1 was obviously less than that in T0 (P0.05). The root length in T2 and T1 shared no statistic difference and the root resorption did not occur after the orthodontic treatment (P>0.05). The distance from alveolar ridge crest to CEJ did not result in alveolar resorption after orthodontic treatment (P>0.05). The changes of density of alveolar bone in T1 were better than that in T0 while after the orthodontic treatment, it decreased. Conclusions: The periodontal treatment before orthodontic treatment plays an efficient role in controlling the periodontal disease and meanwhile, creates a good condition for further orthodontic treatment to restore both good appearance and masticatory function of teeth.
