Adjunctive use of locally delivered host-modulators in intra-bony defects as part of step 2 periodontal therapy: systematic review, meta-analysis and trial sequential analysis.

BACKGROUND

This systematic review and meta-analysis aimed at investigate the role of locally delivered host-modulators in combination with step 2 of periodontal therapy in reducing probing pocket depth, improving clinical attachment level and reducing bone defect depth in intra-bony defects.

HIGHLIGHT: RCT with at least 6 months follow-up were included in this study. Risk of bias assessment was performed with Cochrane collaboration tool and Grade GRADEpro. In addition, meta-analysis and trial sequential analysis were used to aggregate the available evidence. 22 studies met the inclusion criteria and were included in this systematic review. At 6 months locally delivered host-modulators significantly improved PD and CAL and bone defect depth.

CONCLUSION

Considering the emerging role of host-inflammatory response in the treatment of periodontitis, several studies are exploring the role of locally delivered host modulators as an adjunct to step 2 of periodontal therapy.
