Interleukin-1β activity in gingival crevicular fluid of abutment teeth with temporary fixed restorations versus final fixed restorations: Prospective observational study.

Research Abstract

To compare the effect of temporary fixed restorations to final fixed restorations on gingival health of abutment tooth by evaluating the level of IL-1β in gingival crevicular fluid (GCF) as an inflammatory biomarker. Subjects and Methods It was a nonrandomized prospective observational study. Samples of GCF were collected from 24 participants with provisional and permanent definitive full-coverage restorations with subgingival margin placements at three intervals for each participant: Interval 1, after preparation and immediately before cementation of temporary fixed restoration. Interval 2, after two weeks of temporization and before receiving the final fixed restoration. Interval 3, after two weeks of final fixed restorations. GCF were collected from gingival crevice of the abutment tooth by pre-prepared filter paper with dimensions of 2mmx13mm. They were prepared for IL-1β concentration assay by enzym
