Measurement and analysis of alkaline phosphatase and aspartate aminotransferase activity levels in gingival cervical fluid after treatment of telescope retained fixed bridge

Objective To explore the role of telescopic crown retainers fixed bridge in periodontal maintenance. Methods A total of 64 abutment teeth were selected from 16 patients and divided into experimental and control groups(n=32 each) . The gingival index and sulcus bleeding index of abutments in the both two groups were detected at 6 and 12 months before and after repair. The alkaline phosphatase(ALP) and aspartate aminotransferase(AST) activity levels in gingival cervical fluid were measured using automatic biochemistry analyzer. Results There were significant differences in GI and SBI between the experimental and control groups,as well as in ALP and AST activity levels(P0.05) . Conclusion Telescope retained fixed bridge might help protect the periodontal tissue of abutment teeth.
