Subjects and Methods: A total of seven subjects presented to the Department of Removable Prosthodontics Clinic, Al Azhar University, Gaza, Palestine, who had old and new complete dentures took part in this study. The inner and outer surfaces of the complete denture bases of both upper and lower dentures were sampled, the samples were cultured, and the bacterial type was determined by microbiological methods. Results: Of the seven subjects studied, five subjects have shown Staphylococcus (STAPH) spp. in the inner and outer surfaces of both upper and lower dentures for the old and the new as well, while one subject has shown the STAPH spp. also on the lower surfaces of both old and new denture, but the upper surfaces showed no bacterial growth. The last subject had grown bacteria on both upper and lower old dentures, but in the new denture, the bacteria grew only in the upper surface. Conclusion: STAPH spp. showed a great prevalence in both old and 1 week of dentures in use as it predominated in the inner tissue surfaces as well as the outer polished surfaces. ER -
