ABSTRACT
Statement of the Problem: Implant-retained overdenture can improve the stability of dentures and prevent bone loss. Overdenture-wearing patients need special hygiene care
Purpose: The aim of this study was to evaluate the effects of various denture cleansers on the retention of Dio orange O-rings
Method and Materials: In this experimental study, 40 Dio orange O-rings were divided into 4 groups [10 O-rings each] and each group was soaked for equivalent of 6 months in the following solutions: 5.25% NaOCl [1:10 dilution], Corega cleanser tabs, Professional cleanser tabs and water [as the control group]. After 6 months, O-rings were tested for 2inch/minutes of tensile force. The peak load-todislodgement was recorded. Data were imported to SPSS18 and were analyzed by One-Way ANOVA and Tukey HSD test [p
Results: Denture cleansing solutions have significant effects on the reduction of retentive value of O-rings [p
Conclusion: This in-vitro study demonstrated that the retention of O-rings was affected when soaked in cleansing solutions. NaOCl caused more reduction in retentive value compared to effervescent cleansers and would not be recommended for cleansing O-rings. These results should be interpreted clinically and the role of other factors in the retention of O-rings should be considered in order to recommend the best cleanser for O-ring overdentures
