[Abstract]
[Objective]
In recent years, despite the increasing use of soft relining materials for removable dentures, effective cleaning methods for denture plaque have yet to be established. Since soft relining materials are more prone to staining than other materials, patient guidance and denture cleaning methods should be carefully considered for postoperative management. We investigate the effects of agar particle blasting on denture plaque on soft relining materials.
[Method]
Artificial plaques were attached to the surface of the soft relining materials(SOFRELINER TOUGH S(Soft), Tokuyama Dental Corporation, Tokyo, Japan) to simulate denture plaque. Agar particles¹⁾(INA AGAR S-6, Ina Food Industry Co., Ltd., Nagano Japan) were blasted onto the surface to clean it. [Results and Discussion]
The surface roughness Ra didn’t change significantly after the agar particles were blasted.
Since agar particles have sufficient cleaning ability against artificial plaques, cleaning soft relining materials with agar particles is expected to be applied clinically in the future.
