dc.description.abstractThe purpose of this study was to evaluate by means of indentation technique the effects of acid hydrolysis and mechanical polishing on the surface residual stresses of two low-fusing ceramic materials: Duceram-LFC (Dentin and Enamel) and Finesse (Dentin and Enamel) porcelains. Sixteen sample bars (25.O mm x 3.5 mm x 2.5 mm) were fabricated for each material, and assigned to 4 surface-treatment groups (4 bars for each group): control, hydrolysis, glazed then polished, and polished then glazed. Surface residual stresses were determined by conventional micro indentation crack technique. A Buehler Vickers indenter contacted the Duceram samples with a 500-gram load for 10 seconds, and the Finesse samples with a 300-gram load for the same time period. A scanning electron microscope (SEM) was used to study surface texture before and after hydrolysis and polishing. Mean crack length values created from the Vickers indenter are shown in (Table l and Table 2). [TRUNCATED]en_US
