Abstract
Objective: To evaluate the effect of various denture cleansing solutions on
retention of pink Locator®
attachments after 1 year
Materials and methods: Thirty-five pink Locator®
attachments (3.0 lbs. Light
Retention) were divided into five groups (seven specimens in each group) and
soaked in different denture cleansers for 1 year. They were Polident®
5
minutes, Fittydent®
, 0.12% Chlorhexidine gluconate, 1% sodium hypochlorite
and tap water as control. The pink Locator®
attachment was tested for
load-to-dislodgement (retentive force; Newton) on a Universal Testing
Machine (Model 5566, Instron Corp, Norwood, MA) in separate soaking time
(before soaking, after simulated soaking for 1 month, 6 months and 1 year).
The percentage of retention loss after soaking in the denture cleansers for 1
month, 6 months and 1 year were compared by groups using the
Kruskal-Wallis Test and then followed by the Mann-Whitney U Test to indicate
which pairs of denture cleansers were different. A p-value ≤ 0.05 was
considered significant.
Results: After 1 month soaking time, there was no significant difference
among the cleansers (p-value > 0.05). After 6-month soaking time, the
retention for attachments soaked in Fittydent®
(median of % retention loss:
-33.49%) and Chlorhexidine gluconate (-27.05%) were significantly higher than
that soaked in tap water (3.81%). There was no significant difference among
tap water, Polident®
5 minutes (-8%) and Sodium hypochlorite (-9.57%). After
1-year soaking time, the retention for attachments soaked in Sodium
hypochlorite (42.58%) was significantly lower than that soaked in other
solutions. The retention for attachments soaked in Fittydent®
(-36.04% ) and
Chlorhexidine gluconate (-29.03%) were significantly higher than that soaked
in tap water (-10.15%). There was no significant difference between tap water
and Polident®
5 minutes (-12.41%).
Conclusion: Polident®
5 minutes had no significant effect on the retention of
pink Locator®
. Fittydent®
and Chlorhexidine gluconate significantly increased
the retention of the attachments. Sodium hypochlorite significantly decreased
the retention, thus it should not be recommended as a routine denture
cleanser.
