Scope of Research
The Oral Microbiology Testing Service (OMTS) Laboratory at the Kornberg School of Dentistry provides commercial diagnostic testing services to practicing dentists and several dental school clinical programs in the U.S. The OMTS Laboratory is licensed by the Pennsylvania Health Department for clinical periodontal microbiology analysis. These services are focused on microbial culture and antibiotic susceptibility testing of dental plaque/biofilm sampled from patients with periodontal disease or failing dental implants.
The OMTS Laboratory also
- conducts self-funded periodontal microbiology research,
- evaluates the quality of dental unit water within the Kornberg School of Dentistry, and
- analyzes biological indicators from the school’s autoclaves to assess their sterilization efficacy and compliance with infection control policies.
Organisms routinely examined for by culture include the following.
- Aggregatibacter actinomycetemcomitans
- Porphyromonas gingivalis
- Tannerella forsythia
- Prevotella intermedia/nigrescens
- Fusobacterium nucleatum
- Campylobacter rectus
- Parvimonas micra
- Streptococcus constellatus
- Streptococcus intermedius
- Enterococcus faecalis
- gram-negative enteric rods/pseudomonads
- Staphylococcus aureus and other staphylococci
- Candida species (yeasts)
Established in 1982 as the world’s first clinical periodontal microbiology laboratory at the University of Pennsylvania, the OMTS Laboratory moved to Temple University in 1997. It is the largest state-licensed, culture-based clinical periodontal microbiology laboratory of its kind in the U.S.
The OMTS Laboratory is inspected and licensed by the Pennsylvania Department of Health for high-complexity bacteriological analysis, and meets the same proficiency and quality control standards required of hospital medical microbiology laboratories. The laboratory is also Clinical Laboratory Improvement Amendments-certified by the U.S. Centers for Medicare and Medicaid Services for human diagnostic specimen testing.
