Evaluating the effect on tensile bond strength between commonly used acrylic denture base material lined with two variety of soft liners after using three varieties of denture cleansers-an in vitro study

Background: Long-term use of denture causes significant changes in its supporting structures and can lead to constant pain discomfort. Soft lining material extensively used field prosthodontics improve fit conventional acrylic resin for restoring optimal health abused oral tissue showing degenerative change. Method: Specially designed metal mould fabrication 80 blocks. Applying soft liner between 2 sample using grouping these samples immersion solution cleansers. These were then divided into groups 40 each applying variety group (L1 L2). Keeping specimen cleanser per day 8 h keeping 3 times a day=equals days treatment. Thus, the 30 days×3 exposure=amount 90 (3 months) exposure tensile bond strength measured universal testing machine (Instron). ANOVA test is applied. Results: Tensile Viscogel with based decreased more Polident followed by Efferdent, Clinsodent least affected water which statistically significant. Conclusions: The clinician should choose considering microbiologic properties cleansers aspects such as compatibility liners.
