Summary
The retention of Locator attachments varied based on color and cleansing agent. Clear attachments lost retention in sodium bicarbonate solutions, while blue attachments were affected by sodium hypochlorite and sodium bicarbonate cleansers.
Area of Science:
- Dental prosthetics
- Biomaterials science
Background:
- Overdenture patients use various Locator abutment attachments.
- Cleansing agents are recommended for overdenture hygiene.
- The impact of different cleansing agents on attachment retention is not well-documented.
Purpose of the Study:
- To evaluate the retention of three types of Locator abutment attachments.
- To assess the effect of three distinct denture cleansing solutions on attachment retention in an in vitro setting.
Main Methods:
- Locator attachments (clear, pink, blue) were tested after simulated 6-month immersion in sodium hypochlorite (NaOCl), sodium perborate, or sodium perborate-sodium bicarbonate solutions.
- A control group was immersed in tap water.
- Attachment retention was measured using a testing machine and analyzed with repeated-measures ANOVA and Tukey HSD tests.
Main Results:
- Clear Locator attachments showed significantly reduced retention after soaking in a sodium bicarbonate-containing cleanser (P=.001).
- Pink Locator attachments exhibited no significant change in retention across different solutions.
- Blue Locator attachments demonstrated significantly decreased retention after exposure to NaOCl and sodium bicarbonate cleansing agents (P=.002).
Conclusions:
- Denture cleansing agents differentially affect the retention of Locator attachments based on their color and inherent retention characteristics.
