Clinical Study of VectorTM System in Periodontal Therapy

Objective To evaluate the clinical effect of VectorTM system in periodontal therapy.Methods In this split mouth self-control design study,58 patients suffering chronic periodontitis were included.After ultrasonic scaling,each patients' teeth in right-side were treated by subgingival scaling and root planning with VectorTM system(test group),another side were performed by Gracey(control group).All clinical parameters including plaque index(PLI),sulcus bleeding index(SBI),bleeding on probing(BOP),probing depth(PD)and attachment loss(AL)were evaluated at baseline,1,3,6 months after treatment.A visual analogue scale was used to evaluate pain scores upon completion of treatment.Results After treatment,both groups showed significant improvement on their examined index,while there were no significant differences between the two groups(P0.05).During SRP,the Vector system reduced discomforting sensations compared with conventional method.Conclusion VectorTM system in periodontal initial therapy can effectively relieve the clinical symptoms and gain reliable clinical results.
