Surface Roughness of Heat Cured Acrylic Resin Versus Acrylic Resin With Titanium Dioxide

The Surface Roughness of Rapid Heat Cured Acrylic Resin Versus Modified Conventional Acrylic Resin With Titanium Dioxide Nanoparticles in Maxillary Single Dentures: A Randomized Clinical Trials

Measurement of surface roughness of tow different material of denture base to find out which material is more hygienic by decreasing the amount of bacterial accumulation.

Using a denture base material as a standard value which is the rapid heat cured acrylic resin and compare it with a new material which is a conventional acrylic resin with addition of titanium dioxide nano particles in surface roughness and measuring it by a device called stylus profilometer this will be done on 20 patients this trial will take about 6 months.
