Objective: The purpose of this randomized، double-blind،controled trial was to
evaluate the clinical and radiographic effects of 0.12% chlorhexidine digluconate gel on
peri-implant (hard and soft tissues surrounding the implant) maintenance.
Mater
ial and methods: Forty patients (80 implants) who received two implants at
least were randomly assigned to two groups: 0.12% chlorhexidine digluconate gel as test
group، and placebo without CHX as control group. Clinical and radiographic parameters
were recorded at day 10، month 2، 4، and 6.
Results: All clinical parameters except PPD showed better results in test group which
had statistically significant reductions (P< 0.05) in modified plaque index، modified
gingival index، modified bleeding index and attachment level compared to the placebo
group. There were no significant differences between groups in probing pocket depth or
radiographic parameter.
Conclusions: The results of this clinical study indicate that twice daily use of 0.12%
chlorhexidine digluconate gel may enhance the peri-implant maintenance.
