Purpose: This randomized controlled trial aimed to study the effects of lining mandibular complete den-
tures with silicone-based resilient denture liners, especially with respect to sensation.
Methods: The trial included completely edentulous patients who were willing to fabricate new set of
complete denture. A random permuted block method (block size: 4) was used to assign participants to
one of the following groups: mandibular conventional denture (CD) group or mandibular denture with
resilient denture liner (RD) group. The outcomes were evaluated using both, objective measures (current
perception threshold (CPT) and pain threshold (PT)) for external stimuli measured using the Neurometer
CPT® and subjective measures (physical pain and psychological discomfort measured using the Japanese
version of Oral Health Impact Profile for Edentulous patients—OHIP-EDENT-J). The outcomes were mea-
sured twice, at immediately after completion of denture adjustments (first measurement), and 3 months
after the completion of denture adjustments (second measurement). All outcomes were analyzed using
the Student t -test. A p -value of <0.05 was considered statistically significant.
Results: CPT was significantly higher with RD than CD only at second measurement with frequency level
of 20 0 0 Hz and 5 Hz. The pain thresholds were significantly higher in the RD group than the CD group.
The physical pain and psychological discomfort scores were significantly lower in the RD group than in
the CD group.
Conclusion: This study concludes that edentulous patients wearing mandibular complete dentures with
silicone-based resilient denture liners dull perception mandibular ridge mucosa and felt less pain than
those without the liners.
