Conclusion Adhesion to the prosthesis base is improved with surface treatments .
Rough surfaces and changes in hardness compromise the material 's serviceability
Purpose The objective of this systematic review is to compare results concerning the properties of adhesion , roughness , and hardness of dental liners obtained in the last ten years .
Surface Roughness Changes in Denture Liners in Denture Stomatitis Patients.
PURPOSE This r and omized clinical trial assessed how surface roughness ( Ra ) in resilient liners was affected by soft tissue health conditions and time-related aspects in patients with complete dentures . METHODS Specimens of acrylic resin ( control ) and denture liners ( silicone-based or acrylic resin-based ) were inserted into the dentures of patients with and without denture stomatitis ( n = 30 ) .  Ra was evaluated before denture insertion and after 7 , 14 , and 21 days of prosthesis wearing . Data were analyzed using three-way analysis of variance and Student-Newman-Keuls test . RESULTS Patients with stomatitis showed a higher Ra ( P < .001 ) , while all liners presented rougher surfaces after 14 days of clinical service , irrespective of the soft tissue health condition . CONCLUSION Ra of the tested denture liners was increased in patients with denture stomatitis . It is presumed that a longer wearing period will result in rougher surfaces
