Background: Peri-implant mucositis is a bacterial and inflammatory
disease of implant surrounding soft tissues. Chlorhexidine (CHX) associated with
PVP-VA (Polyvinylpyrrolidone/vinyl acetate) has an adjuvant function in the
antibacterial activity: it protects the film-forming layer, due to polymer, from
microbial contamination or over-infection, and prolongs its permanence, without a
direct action on the tissues and wounds. Sodium DNA is able to improve gingival
trophism. The aim of the study was to compare a gel with CHX and
antidiscoloration system (A.D.S.) 0.5% with the addition of PVP-VA and sodium
DNA with a placebo gel without chlorexidine in peri-implant mucositis treatment.
Methods: Trial design: A single center randomized controlled pilot
clinical trial was conducted on a total of 24 patients with mucositis, randomly
allocated into two groups. In the group (A) (n = 12) patients were treated with a
gel with CHX + A.D.S. 0.5% while a placebo gel was used in the group (B) (n =
12). Outcome: Plaque Index (PI) (primary outcome), Bleeding on probing (BOP) and
Gingival Index (GI) (secondary outcomes) were assessed at baseline and at 2 weeks
after treatment period. Results: Mean PI score recorded at baseline was
2.4
