| Abstract | ||
| Pressure indicator during insertion of removable prosthesis can help identify potential areas of discomfort resulting from different errors during prosthetic work, correct diagnosis of specific problem relies on proper application of pressure indicator. A study was therefore, undertaken to measure pressure area of upper and lower complete dentures using different types of pressure indicating materials. Thirty two processed dentures were examined. All of them had a clear tissue surface with no sharp projections to minimize patient discomfort. Three different pressure indicating materials ; zinc oxide, alginate, and extra light silicon were used, surface area measurements were evaluated for each material. Setting time, ease of remove, no. of sites, and coast of the materials were also evaluated. The results of this study showed that there was a significant difference in pressure area measurements between the three different pressure indicating materials, while there was no difference between alginate and silicon- alginate and zinc oxide materials, while there was a significant difference between silicon and zinc oxide pressure materials. Setting time appreciation showed that silicon set in shorter time than alginate and zinc oxide materials, while for cost variable discussion silicon material revealed a higher cost means than both alginate and zinc oxide materials. In the present investigation data collected showed a significant difference in pressure area measurements between silicon and zinc oxide materials. Silicon, and alginate pressure materials showed no difference in pressure area readings between them. | ||
