Denture Liners: A Systematic Review Relative to Adhesion and Mechanical Properties

Table 3

Included studies related to the hardness and roughness for hard denture liners.

Author/year	Method used	Study objectives	Outcomes
Urban et al./2009	Vickers hardness tester and surface roughness tester	Effect of water-bath postpolymerization (PP), degree of conversion, flexural strength, and microhardness, reline resins	Hardness increased by PP except Ufi Gel Hard
Machado et al./2009	Vickers hardness tester and surface roughness tester	Hardness and surface roughness, microwave and chemical disinfection, reline resins, denture resin	Hardness, Lucitone 550, not affected. Kooliner and DuraLiner II, increased, except Lucitone 550. Microwave 2 cycles, increased roughness. Tokuyama did not increase. Hardness, small decrease, 30 days
Izumida et al./2014	Surface roughness tester	Roughness, denture cleansers, reline resin	Roughness, reduction, brushing and sodium perborate and/or chlorhexidine gluconate
Machado et al./2012	Surface roughness tester	Roughness, denture, hard chairside and resilient lining materials	Initial roughness, no differences, Lucitone and Sofreliner, Tokuyama Rebase II and New Truliner. Chlorhexidine 4%, increased roughness, Ufi Gel Hard and Sofreliner, after disinfection
Dias Panariello et al./2015	Knoop hardness and surface roughness tester	Roughness (brushing, immersion). Hardness, color, Lucitone 550 (L), and reline resin	Roughness, decreased to L. Hardness, NaOCl and perborate, decreased to L. Hardness, decreased for T
Machado et al./2011	Surface roughness tester	Roughness denture, hard chairside and resilient lining materials	Roughness, Tokuyama Rebase II and Ufi Gel similar or < New Truliner. Roughness, Lucitone and Tokuyama Rebase II, not affected by immersion and disinfection
