Slime production by coagulase-negative staphylococci in the infected pulps
1Department of Endodontics, Gazi University, Faculty of Dentistry, Turkey.
Abstract:
In this study; slime factor which is produced by coagulase negative Staphylococci was investigated in infected pulps of 145 primary and permanent teeth. Staphylococci were isolated in 27% of the cultures and all of the isolated Staphylococci were coagulase negative (CNS) in permanent teeth whereas 75% of isolated Staphylococci were coagulase negative in primary teeth. Slime production rate was the same for both groups and 22% of CNS were found slime positive. It is thought that slime production is important not only in endodontic microbiology, but also in other fields of dentistry for the explanation of the pathogenesis of infection.
Insights
Coagulase-negative Staphylococci (CNS) were studied in infected teeth. Slime-producing CNS were found in 22% of isolates, suggesting slime
Area of Science:
- Microbiology
- Dentistry
- Endodontics
Background:
- Coagulase-negative Staphylococci (CNS) are implicated in various infections.
- The role of slime factor production by CNS in dental infections requires further investigation.
Purpose of the Study:
- To investigate the prevalence of slime factor production by CNS in infected primary and permanent teeth.
- To assess the significance of slime production in endodontic microbiology and dental pathogenesis.
Main Methods:
- Isolation and identification of Staphylococci from 145 infected primary and permanent teeth.
- Determination of coagulase negativity and slime production rates among isolated Staphylococci.
Main Results:
- Staphylococci were isolated from 27% of teeth.
- All Staphylococci isolated from permanent teeth were CNS; 75% from primary teeth were CNS.
- 22% of CNS isolates exhibited slime-positive characteristics, with similar rates in both primary and permanent teeth.
Conclusions:
- Slime production by CNS is a relevant factor in infected teeth.
- Slime factor may play a significant role in the pathogenesis of endodontic and other dental infections.
