Background: The aim of this study is to determine in a randomized trial the impact on treatment outcome after 12 months of different subgingival irrigation solutions during scaling and root planing (SRP). Methods: Fifty‐one adult volunteers with generalized chronic periodontitis were treated by full‐mouth SRP using 0.9% sodium chloride, 0.12% chlorhexidine digluconate, or 7.5% povidone–iodine for subgingival irrigation during SRP. Before SRP and after 3 and 12 months, probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP) were recorded. Subgingival plaque samples were analyzed for Aggregatibacter actinomycetemcomitans , Porphyromonas gingivalis , Tannerella forsythia, and Treponema denticola . Results: PD, CAL, and BOP were significantly improved in all groups after 12 months ( P <0.001 to P = 0.044). No significant differences were seen among the groups for all sites and sites with 4 to 6 mm PD at baseline. The povidone–iodine group had the highest clinical improvements. The counts of A. actinomycetemcomitans and P. gingivalis were significantly reduced after 12 months ( P = 0.045 and P = 0.002) using povidone–iodine. Significant differences between the groups were seen after 3 months for A. actinomycetemcomitans and P. gingivalis , and after 12 months for T. forsythia . Conclusions: No differences were seen among the groups in the clinical results after 12 months. Regarding the microbiologic results, a slight benefit seemed to derive from the use of povidone–iodine.
