This course attempts to determine the usefulness of various microbiological testing systems for the management of periodontitis patients.
Upon completion of this course, participants should be able to do the following:
- Identify microorganisms that have been implicated in periodontal disease.
- Explain the importance of antimicrobial susceptibility testing.
- Discuss the purpose of microbial testing during the treatment evaluation phase.
Microbiological tests in periodontics can be of great help in determining the characteristics of a pathogenic infection, prescribing the optimal antibiotic regimen and monitoring the effectiveness of treatment. However, they are not without potential pitfalls. Current microbiological tests vary considerably in sensitivity and specificity. A false positive test result may lead to unnecessary therapy and patient distress. A false negative test result may prompt the withholding of necessary therapy and the subsequent progression of disease. Also, diagnostic tests can be relatively expensive and uncomfortable for patients. This article attempts to determine the usefulness of various microbiological testing systems for the management of periodontitis patients.
