Abstract

Purpose: To evaluate the retention capability of three Locator attachments after soaking in
three different cleansing solutions.
Materials & Methods: Three implants were embedded into acrylic block, Locator abutments
were placed onto the implants. 120 locator attachments divided into three groups (40 each): pink,
white and purple Locator attachments were soaked in different denture-cleansing solutions: (water
as control group, Efferdent, 5.25% Sodium Hypochlorite, Tantum Verde Mouthwash) ten each
for a time resembling one year of clinical use. The Locator attachments were tested for load-todislodgement
(retentive force; Newton) with a Universal Testing Machine. Data were collected,
tabulated and statistically analyzed using Two Way ANOVA test followed by the Tukey’s HSD test
(α ≤ 0.05).
Results: There were no statistical significant differences between water, Efferdent and Tantm
Verde mouthwash (P>0.05) for all types of locator attachments while sodium hypochlorite gave
statistical significant lower retention values and retention loss percentage (P< 0.05) than that
immersed in other solutions.
Conclusions: Within the limitations of this study Efferdent and Tantum Verde mouthwash can
be used as denture cleanser while sodium hypochlorite is not recommended.
