Evaluation of Sodium Hypochlorite as a Denture Cleanser
Denture Condition: Influence on Masticatory Performance, Volatile Sulfur Compounds and Presence of Biofilm
The present study tried to integrate all aspects of denture care: patient satisfaction with the treatment, denture decontamination and base material defects after decontamination processing.
Considering that it is necessary to stipulate a simple and effective routine protocol for denture cleaning the aim of this study was to evaluate, in vivo, the efficacy of 0.5% sodium hypochlorite (NaOCl) as a denture cleanser and its effect on color stability and surface roughness of complete dentures. The patients' satisfaction with the denture cleaning method was also assessed.
