Abstract: Objective:To explore the effects of double circumferential fibrotomy(CF)in the improvement of periodontal attachment of the teeth with periodontal disease.Methods:22 migrated incisors of 4 adults were randomly assigned to one-time CF group (T1 )and double CF group(T2)by center line.Periapical intraoral radiographic examination was performed using paralleling technique at pre-and post-leveling-alignment stage of the teeth.Root length,crown-root ratio and the distance of CEJ-AC were measured.The periodontal in-dicators were also recorded during the orthodontic treatment.Data were statistically analysed by comparative t-test.Results:CEJ-AC and crown root ratio reduction was greater in T2 group than those in T1 group(P <0.01 ),but the periodontal indices did not show sig-nificant difference between the 2 groups(P >0.05).Conclusion:Double circumferential fibrotomy can improve periodontal attachment, reasonable orthodontic force does not lead to remarkable root resorption of the periodontitis inflicted teeth.
