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.

Comparative evaluation of shear compressive bond strength between cross-linked acrylic resin denture base and cross-linked acrylic resin teeth with different modifcations of their ridge lap surfaces.

A major problem commonly observed in denture wearer is the detachment of artifcial tooth/teeth from acrylic denture base. The problem was grave when porcelain teeth used along with the then available denture base materials. The bond formed was purely mechanical and hence debonding of teeth from denture base was a frequent occurrence.
