Quantitative relationship between yeast and bacteria in denture-induced stomatitis
Scandinavian Journal of Dental Research
|April 1, 1983
Summary
Denture plaque analysis revealed higher yeast and bacteria counts in patients with denture-induced stomatitis. This suggests microbial overgrowth contributes to stomatitis, with yeast playing a significant role.
Area of Science:
- Oral microbiology
- Denture stomatitis research
Background:
- Denture-induced stomatitis is a common oral condition.
- Microbial plaque on dentures is implicated in its development.
Purpose of the Study:
- To quantitatively assess yeast and bacteria in denture plaque.
- To investigate the relationship between microbial counts and denture stomatitis.
Main Methods:
- Collected 7-day-old denture plaque from edentulous subjects.
- Used quantitative culture methods to identify yeasts and bacteria.
- Compared microbial loads between stomatitis patients and healthy controls.
Main Results:
- Significantly higher yeast and bacteria counts were found in stomatitis patients.
- Yeast constituted a higher percentage of microbial counts in stomatitis patients.
- Higher initial yeast counts correlated with improved palatal mucosa after treatment.
Conclusions:
- Increased plaque formation and microbial overgrowth, particularly yeasts, contribute to denture-induced stomatitis.
- Yeast antigens and toxins are significant factors in stomatitis.
- Bacteria may also play a role in the pathogenesis of denture stomatitis.
