PURPOSE: The purpose of this in vitro study is to assess the effect of ozone cream on C. albicans on acrylic resin denture plates. METHODS: 120 experimental denture plates were prepared with heat-polymerized acrylic resin (15mm XI5 mm X 3 mm; Dentsply, LUCITONE 199 Resin, York, PA) according tothe manufacturer's instructions, were contaminated with C. albicans then treated with ozonated cream. Results were compared with contaminated plates in ultrasonic sterile water as a negative control group and contaminated plates treated with chlorhexidine as a positive control group. • Thirty acrylic resin surfaces were polished with pumice and rubber wheels and treated with ozonated cream Pol-Oz • Thirty acrylic resin surfaces were polished with pumice and rubber wheels and treated with ultrasonic sterile water. Pol-Wat (Negative Control) • Thirty acrylic resin surfaces were polished with pumice and rubber wheels and treated with chlorhexidine. Pol-CHX (Positive Control) • Thirty acrylic resin surfaces were rough and were treated with ozonated cream. Rou-Oz After treatment, the number of attached C. albicans was counted by using optical microscope. RESULTS: The analysis demonstrated that here were statistically significant differences amongst the four groups. A p=0.017 was observed when Pol-Wat was compared with Rou-oz group. In addition, there was a significant reduction in the colony count when comparing the Pol-Wat with Pol-Oz group (p=0.001). Furthermore, the p values for Pol-Oz were significantly lower when compared with the remaining three groups (p= 0.00001, 0.00001 and 0.001 respectively). CONCLUSION: Ozone cream was highly effective for inhibiting C. albicans in pure cultures on polished denture acrylic resin plates.
