---|---|---|---|---|---|
Asadzadeh et al. [45] | 2012 | Peri-implant tissues | 20 patients | 20 implants | Correlation between the increase in peri-implant BOP from 1 to 6 months after loading and an increase in colonies of Streptococcus spp. and Peptostreptococcus spp. |
Neilands et al. [46] | 2015 | Peri-implantitis vs. peri-implant health |
50 patients (25 peri-implantitis; 25 healthy) |
1 implant per patient |
Highly variable microbial composition. Significantly higher prevalence of Porphyromonas/Prevotella and anaerobic Gram positive cocci in peri-implantitis. |
Tripodakis et al. [47] | 2011 | Peri-implant tissue vs. periodontal disease |
20 patients |
20 periodontal sites that became 20 peri-implant sites |
Spirochetes in peri-implant samples: 69% vs. 2% at baseline and 12 months, respectively. Higher colony forming units (CFU)/ml in samples from periodontal sites. |
de Waal et al. [48] | 2013 | Peri-implantitis |
30 patients (15 placebo; 15 test [chlorhexidine]) |
79 implants (48 placebo; 31 test) |
Sixty of the 79 implants were positive at baseline. A.a. not detected. Both procedures reduced P. gingivalis, P. intermedia, T. forsythia, F. nucleatum, P. micra and C. rectus. |
