Title : Adjunctive Subgingival Irrigation with Silver Nanocolloid to Root Debridement: A Randomized Split-Mouth Controlled Trial on Clinical Periodontal Outcomes
Author(s) : Dr. Hannah Müller, Dr. Zara Khan
Abstract :
Local delivery of antimicrobials has been investigated as an adjunct to conventional therapy. This study aimed to
determine the efficacy and clinical outcomes of silver nanocolloid irrigation as an adjunct to mechanical root
debridement in the management of periodontitis. Fifty one (51) patients with the presence of at least 1 pocketing
site of ≥ 6mm in both contralateral half mouth after periodontal assessment were enrolled. In this split mouth design
study, pocketing sites of ≥ 6mm were treated with subgingival root debridement in combination with either silver
nanocolloid or saline subgingival irrigation. Bleeding score showed a significant reduction over the observation period
in control group (p = 0.034). The probing pocket depths were reduced for both groups, with a significant treatment
effect (p < 0.001) from baseline to 6-week review. Also, there was a notable reduction in overall median pocket depth
in both genders. In conclusion, within the limitations of the study, no additional benefits were observed with the use
of silver nanocolloid irrigation following mechanical debridement.
