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

Table 4

Included studies related to in vivo studies.

Author/year	Observation period	Method used	Study objectives	Outcomes
Mutlay et al./2008	3, 6, and 12 months	Evaluation criteria: physical integrity, surface detail, adhesion, color, odor, plaque accumulation, resilience, hygiene, mucosal condition, and signs of fungal colonization	Clinical performance denture liners, 12 months	Roughening, posterior region
Bail et al./2014	Rats used palatal plates, 14 days	A roughness tester	Roughness, soft liners	Roughness, Dentuflex and Dentusoft, similar. Trusoft, rougher than Dentusoft. Ufi Gel P, lowest roughness (14-day)
Ogawa et al/2016	Original and 1-month hardness, after oral exposure	Shore D hardness	Denture liners changes, 1-month clinical setting	Hardness, changes influenced, patients’ characteristics
