Clinic Study On Changes Of Occlusal Force And Periodontal Parameters Following Initial Therapy Of Chronic Periodontitis

Objective To evaluate the changes of the occlusal force and the clinical periodontal parameters following initial therapy in chronic periodontitis, in order to help the clinicians and patients to preserve the systemic periodontal treatment.Methods: two molar with similar moderate periodontaitis from two side of 27 chronic periodontitis patients were randomly divided into two groups (P group and S group) . S group were treated with supragingival scaling; P group were treated with scaling and root planning. The data of the occlusal force, PD PLI SBI and GR was taken and analysised at pretreatment and 1st 3rd, 6th month separately after treatment by t-test.Results: There were significant differences between two groups in 3rd, 6th month after treatment. Root planning group get more improvement in occlusal force PD SBI and GI.Conclusion: Compared with supa rgingival scaling, root planning is more effective in the increasing of the occlusal force and the decreasing of PD and SBI.
