| Abstract | ||
| The aim of this study was to measure the effect of different immersion period up to (7) days of acrylic denture base materials (heat cure acrylic Vertex and QD, and cold cure acrylic Miky-red and QD) in three types of disinfectant solutions (0.525% Sodium hypochlorite, 0.2% Chlorhexidine and 2% acidic Glutaraldehyde) on the Surface roughness. One hundred eighty acrylic plates were prepared from a base plate wax of (20mm × 10mm×2.5 ± 0.03mm) dimension using a conventional denture processing technique. From each type of acrylic denture base materials, (45) acrylic plates were prepared, which where intern divided into three groups: (15) unpolished (inner-side) Surface, (15) polished by conventional technique and (15) polished by a modificated polished technique. The surface roughness was measured by a prethometer. The results, revealed that there was a significant difference at (1%) level between the materials used, solution used, types of polishing technique and the time of immersion. The cold cure acrylic denture base material type (Miky-fed) showed the highest degree of the surface roughness, Photomicrograph microscopical study of the acrylic beads (mer-unit) showed the effect of the size of the beads on the surface roughness. It was concluded that the modificated polishing technique produces a Smoother surface for the acrylic denture base materials, the solutions and duration of immersion up to seven days showed a statistical significant difference but practically they can be used for denture disinfecting. | ||
