Clinical Evaluation Of The Application Of Fixed Periodontal Splint In Periodontal-Endodontic Combined Lesions Case Reports

Objective: To evaluate the clinical effect of fixed periodontal splint(PFM continuous crowns or PFM fixed bridge) applied in periodontal-endodontic combined lesions.Methods: 25 patients with periodontal-endodontic combined lesions were inclouded. 55 teeth with periodontal-endodontic combined lesions of the 25 patients were treated with periodontal therapy and root canal therapy followed by fixed periodontal splint. Prior to treatment and 6 months later the following parameters were evaluated: masticatory efficiency, bleeding index(BI), probing depth(PD), attachment loss(AL) and tooth mobility(TM).Results: 6 months later, the PD and the AL of the teeth reduced, and the masticatory efficiency of the teeth improved.Conclusion: For combined periodontal-endodontic lesions, periodontal therapy and root canal therapy followed by fixed periodontal splint was an effective therapy method.
