Abstract

PURPOSE
The purpose of this study was to evaluate the transmission of candida in denture by dental polishing lathe.
MATERIALS AND METHODS
Maxillary complete dentures made from the same model were infected with Candida albicans. Polishing wheels were keep in various chlorhexidine solution and distilled water for an hour. The infected dentures were polished by prepared dental polishing lathe with sterile pumice and distilled water. And then sterile maxillary complete dentures were polished with same method. Polishing surface was wiped with a cotton swab and the sample was regrown for checking Candida albicans.
RESULTS
All polishing wheel with chlorhexidine resist fungal infection. But the polishing wheel with distilled water is infected with Candida albicans.
CONCLUSION
A chlorhexidine is highly efficient in fungal infection prevention on dental polishing lathe.
