Infection - microbiological diagnostics

Key points

Marginal bone loss can lead to deepened pockets. Superinfection can develop periimplantitis
Microbiological sensitivity testing, may be clinically relevant when periimplantitis; evidence is present

Microbiota parameters

Presence/number of implants influences aerobe and anaerobe species in saliva and on tongue in edentulism.

Subgingival microbiota in periimplantitis vary according to studies. Less periodontal pathogens than in partial edentulism. Prevotella nigrescens, Fusobacterium nucleatum, P. gingivalis, T. forsythia, Treponema denticola or Aggregatibacter actinomycetemcomitans have been associated with peri-implantitis. Microflora different from periodontitis, with high numbers of peptostreptococci or staphylococci. Typical are enteric rods, staphylococci and yeasts.

Antibiotic medication selection

For periimplantitis the beneficial effects of a systemic antibiotic, as adjunct to mechanincal/surgical treatment remain unproven. Whether the composition of submucosal microbiota is a determining factor for the effectiveness of therapy remains unsubstantiated. Microbial testing can help selecting proper antibiotic by detecting resistant species.

Microbiology tests

Available tests for on an outpatient population:

phase-contrast microcopy
culturing
latex agglutination test
checkerboard DNA-DNA hybridization
polymerase chain reaction

Phase-contrast microscopy:

Simple and fast chair-side test which provides proportion of cocci/rods/filaments and motile organisms. Increased % of motile organisms has been associated with aggressivety of periodontitis; this relationship is not established for periimplantitis.

Culturing

Culturing is technique sensitive and time-consuming. Determines sensitivity towards antibiotics. Paper points are inserted in the periimplant pocket and transported in a vial to the laboratory.

Latex-agglutination test

Consists of beads coated with specific antibodies. When contacting target antigens from the sample, à clumping of beads. Simple and rapid.

Checkerboard DNA-DNA hybridization

Optimal test for complex ecosystems. Allows identification of large numbers of species in many samples. ≥104 bacteria allow detection.

Polymerase chain reaction

Involves amplification of DNA sequence by a primer. If amplification occurs, presence of target species proven. ≥ 10 bacteria can be detected. Biofilm may contain enzymes which inhibit reaction.

Inflammation and infection

Inflammation can be limited to the soft tissue around the implant (mucositis) or involve the underlying bone tissue as well (peri-implantitis). Infection can be caused by various risk factors, such as inadequate hygiene and patient compliance...

Medication

the patient might need or appreciate adequate medication against pain and swelling, for example Paracetamol, Acetylsalicylicacid (ASA), or of the non-steroidal anti-inflammatory drug...

Oral hygiene instructions

All tissue surfaces, prosthesis surfaces and implant surfaces should be accessible by oral hygiene aids like toothbrushes, interdental brushes and dental floss or dental tape. It is paramount that, during treatment planning...
