The effect of denture cleansers on temporary soft liners

Area of Science:

• Materials Science
• Biomaterials Engineering
• Dental Prosthetics

Background:

• Dental liners are crucial components in prosthetic applications.
• The interaction between dental liners and common cleaning agents is not fully understood.
• Material compatibility is essential for the longevity and performance of dental prosthetics.

Purpose of the Study:

• To evaluate the impact of nine different cleansers on the properties of commonly used dental liners.
• To determine which liner materials exhibit superior resistance to degradation from cleaning solutions.
• To provide data-driven insights for selecting appropriate dental liners based on cleanser compatibility.

Main Methods:

• Circular samples of eight different dental liner materials were prepared.
• Samples were immersed in nine distinct cleanser solutions, with daily solution changes for one month.
• Six key properties were quantitatively assessed: color change, porosity, surface distortion, size change, water sorption, and solubility.
• Statistical analysis was employed to evaluate liner and cleanser performance.

Main Results:

• No single property could determine optimal liner selection; a multifactorial approach is necessary.
• Lynal, Tissuedyne, F.I.T.T., and Hydro-Cast demonstrated the highest resistance to cleanser effects, in descending order.
• Viscogel, Softone, and Veltec were the most adversely affected liners.
• Clorox/Calgon and Miller cleansers showed comparable overall performance, with Clorox/Calgon being compatible with six out of eight liners.
• Liner material thickness did not significantly influence the observed effects of the cleansers.

Conclusions:

• Dental liner selection should consider a comprehensive evaluation of multiple material properties in conjunction with expected cleaning protocols.
• Certain liner materials (Lynal, Tissuedyne, F.I.T.T., Hydro-Cast) offer better durability against common dental cleansers.
• Cleanser choice significantly impacts liner integrity, with Clorox/Calgon and Miller exhibiting moderate to good compatibility across various liners.
