Introduction: The main goal for preventing and controlling periimplantitis is the reduction of oral bacteria load, through home and professional procedures. The aim of the present study was to evaluate the impact of a professional standard non-surgical therapy and the motivation to the use of domiciliary interdental brushes (Gunchi - South Korea) in a cohort of 75 patients with at least 1 implant placed with a minimum of 2 years follow-up and maximum 5 years.

Materials and methods: Seventy-five patients were screened on the basis of specific inclusion and exclusion criteria and were grouped into three different controlled cohorts based on their age: Group 1: patients aged 25-39 years; Group 2: patients aged 40-54 years; Group 3: patients aged 55-69 years. All subjects received oral hygiene instructions and a standard professional non-surgical treatment with ultrasonic debridement, polishing and ozonated water rinse by a specific professional device for a minute (Aquolab® - Italy). After the education and motivation session patients were instructed to use interdental aids (interdental brushes, Gunchi South Korea).

Patients were monitored for a total of 2 months follow-up. The following clinical parameters were measured on each patient before dental debridement and oral hygiene motivation (T0) and at 30 days (T1) and 60 days (T2):

Probing pocket depth (PPD), Recession (Rec), Modified Plaque Index (mPI) and Modified Sulcus Bleeding Index (mSBI).

Results: Each group showed significant improvements on Probing Depth (PD), mSBI and mPI at T1 an T2 follow-up. No statistically significant differences were found in terms of soft tissue recession. The difference between T2 and T0 and between T1 and T0 were computed on each parameter (ΔPPD, ΔRec, ΔmPI, ΔmSBI) for the comparison in efficacy between groups using the T-student test (p-value<0.05). The group-2 had statistical significant improvement in PPD respect to group-3, and in mPI and mSBI then group-1 respectively in T1 and T2 (p-value<0.05).
