This systematic review and meta-analysis examined the oral microbiota differences among dentate, edentate, and complete denture-wearing older adults (≥65 years). The analysis included 15 studies and found that edentate individuals had lower microbial diversity and distinct patterns compared to dentate individuals. Notably, Porphyromonas gingivalis and Tannerella forsythia were less prevalent in edentate individuals (p<0.001).
Key findings
- Edentate individuals exhibited lower microbial diversity compared to dentate individuals.
- Porphyromonas gingivalis and Tannerella forsythia were less prevalent in edentate than dentate individuals (p<0.001).
- Denture stomatitis was associated with microbial dysbiosis in complete denture wearers.
- P. gingivalis and T. forsythia increased after CD insertion for a short term (p=0.002 and p=0.006, respectively).
Why it matters
Understanding the differences in oral microbiota among older adults can inform strategies for managing oral health, particularly in those with dentures. This knowledge is crucial for preventing complications such as denture stomatitis and maintaining overall mucosal health.
