Hypothesis
This study investigates the proteolytic activities of certain periodontal bacteria and the effects of synthetic proteinase inhibitors on proMMP-9.
Conclusion
The study concludes that periodontal bacteria can activate proMMP-9 and that synthetic proteinase inhibitors can slightly reduce bacterial proteolytic activities.
Supporting Evidence
- All studied periodontal bacteria produced proteinases that could fragment proMMP-9.
- Synthetic proteinase inhibitors showed slight but significant effects on bacterial proteolytic activities.
- P. gingivalis exhibited the strongest proteolytic activity among the bacteria tested.
- ILM and EDTA were among the inhibitors that significantly affected bacterial proteinases.
Takeaway
Some bacteria in your mouth can break down proteins that help keep your gums healthy, but certain medicines might help stop this from happening.
Methodology
The study involved analyzing the proteolytic activities of various periodontal bacteria using zymography and Western immunoblot techniques.
