Abstract
Objective: To evaluate the effect of locally applied bio-glass on the teeth hypersentivity and periodontal recovery after subgingival scaling and root planing. Methods: In this double blind study, 60 patients with chronic periodontitis were included and were randomly divided into four groups of 15 patients: bio-glass powder and bio-glass paste group (Po + Pa), bio-glass powder group (Po), bio-glass paste group (Pa) and control group. Powder was applied in pockets after subgingival scaling and root planning (SRP) and paste was used as toothpaste for 6 weeks. Periodontal indices and the severity of tooth hypersensitivity were recorded. Results: Obvious mitigation of tooth hypersensitivity was observed in bio-glass powder or paste applied patients within the fist three weeks after SRP. Only few patients presented teeth hypersensitivity in the 6th week after SRP. In the 6th week after SRP, bleeding index significantly decreased in bio-glass powder or paste applied patients. More pocket depth and clinical attachment level reduction was found in bio-glass powder applied patients. Application of bio-glass powder or paste improved clinical attachment level in the 3 rd month after SRP. Conclusion: The hypersensitivity after subgingival scaling could be relieved without any treatment in 6 weeks, while the bio-glass powder and the 7％ bio-glass paste could reduce the prevalence and the severity of it. Further more, bio-glass also improved the clinical outcomes of subgingival scaling via its bacteriostatic action.关键词
