A Comparative Evaluation of Shear Bond Strength Between Two Commercially Available Heat Cured Resilient Liners and Denture Base Resin with Different Surface Treatments.

Background: Soft denture liners are widespread materials used in prosthetic dentistry. Their mechanical properties have to meet several key requirements such as adequate bond to denture base resins in order to provide right function of masticatory system and oral hygiene.

Aim: To evaluate and compare the shear bond strength between two commercially available liners and polymethyl methacrylate (PMMA) denture base resin with different surface treatments.

An in-vitro evaluation of effect of EDTAC on root dentin with respect to time.

Background: The present study was devised to evaluate the effects of 17% EDTAC on smear layer removal and on the dentin structure after irrigation with 1 minute and 10 minutes.

Materials & Methods: One hundred extracted mandibular molars with two separate mesial canals were selected; mesiobuccal canal was instrumented to size 30 file with crown down technique. One half of each root (either mesial or distal) was randomly selected and prepared for scanning electron microscopic (SEM) evaluation that was then cut longitudinally into two equal segments.

Epidemiological Study to Evaluate the Prevalence of Dentine Hypersensitivity among Patients.

Background: Dentine hypersensitivity (DH) is a common finding with different prevalence rate. The aim of this study was to evaluate the prevalence of DH and associated risk factors.

Materials & Methods: This cross-sectional survey was done among patients coming to dental hospital.
