Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: At baseline, 1, 3, 6 months, full-mouth plaque score (FMPS), full-mouth bleeding score (FMBS), probing depth (PD), bleeding on probing (BOP), modified gingival index (mGI), and modified plaque index (mPlI) were assessed.
Primary purpose: TREATMENT

Brief summary: To evaluate the naturally occurring peri-implant mucositis (PM) treatment by means of non-surgical sub-marginal peri-implant instrumentation (NSPI) with or without full-mouth disinfection approach (FMD). Specifically, the primary outcome of the present study compared the efficacy of NSPI and full-mouth disinfection (FMD) with respect to NSPI and placebo in the treatment of PM at 6 months follow-up. The secondary outcome evaluated the influence of possible predictors on the BOP changes among all follow-up sessions.

Detailed description: Fifty-six patients with 85 Implants affected by PM were randomly assigned to test (NSMD+FMD) or control procedures (NSMD + placebo). At baseline, 1, 3, 6 months, full-mouth plaque score (FMPS), full-mouth bleeding score (FMBS), probing depth (PD), bleeding on probing (BOP), modified gingival index (mGI), and modified plaque index (mPlI) were assessed. Furthermore, the proportions of Aggregatibacter Actynomycencomitans, Porphyromonas Gingivalis, Tannerella Forsythia and Treponema Denticola were also recorded. The BOP reduction was set as a primary outcome and the patient was considered statistical unit. Data were analysed to assess BOP reduction at a 6-month follow-up and to identify significant predictors of implant-site BOP through mixed generalized linear regression.

Eligibility criteria: Inclusion Criteria:

* age ≥18 years old;
* implants with smooth necks supporting cemented or screw-retained single-unit crowns with at least one BOP-positive site (Berglundh et al., 2018),
* implants placed in both maxilla and mandible
* patients with gingivitis or treated periodontitis with the absence of residual PD ≥5 mm
* presence at least of 2 mm of keratinized mucosa (KT) at implant sites

Exclusion Criteria:

* presence of systemic diseases;
* pregnancy or lactating;
* use of inflammatory drugs or antibiotics within 3 months prior to study recruitment;
* implants with modified (i.e., micro-rough) necks;
* interproximal open contacts between implant restoration and adjacent teeth;
* peri-implantitis (Berglundh et al., 2018)
