Abstract
Aim
The aim of the present study
was to evaluate the effect on peri-implant mucosal inflammation from the
use of a novel instrument made of chitosan in the non-surgical
treatment of mild peri-implantitis across several clinical centers.
Materials and methods
In this 6-month multicenter
prospective consecutive case series performed in six different
periodontal specialist clinics, 63 implants in 63 patients were finally
included. The subjects had mild peri-implantitis defined as radiographic
bone loss of 1–2 mm, pocket probing depth (PPD) ≥4 mm and a positive
bleeding on probing (mBoP) score. The patients were clinically examined
at baseline and after 2, 4, 12 and 24 weeks, and radiographs were taken
at baseline and at 3 and 6 months. Treatment of the implants with the
chitosan brush seated in an oscillating dental drill piece was performed
at baseline and at 3 months. Reductions in the clinical parameters (PPD
and mBoP) were compared between baseline and the later examination time
points.
Results
Significant reductions in both PPD and mBoP were observed at all time points compared with the baseline clinical measurements (p < 0.001).
The mean PPD and mBoP at baseline were 5.15 mm (4.97; 5.32) and 1.86
(1.78; 1.93), respectively, whereas the mean PPD and mBoP at 6 months
were 4.0 mm (3.91; 4.19) and 0.64 (0.54; 0.75), respectively. Stable
reductions in PPD and mBoP were evident up to 6 months after the initial
treatment and 3 months after the second treatment. All 63 implants were
reported to have stable radiographic levels of osseous support.
Conclusions
This case series demonstrated
that an oscillating chitosan brush is safe to use and seems to have
merits in the non-surgical treatment of dental implants with mild
peri-implantitis. To measure the effectiveness of the method, a
multicenter randomized clinical trial needs to be undertaken.
