| Abstract | ||
| Aim: The aim of this study was to examine the effects of glycerin-coated wax pattern on dental stone surface quality in terms of surface roughness and micro air bubble formation. Method: In this study, a total of 20 modeling wax samples were used for the hydrophilicity test (the contact angle test) divided into 2 groups (control and glycerin-painted). A total of 20 dental stone samples were also prepared for visual and microscopic analysis divided into 2 groups (control and glycerinpainted). Results and conclusion: The contact angle data showed a significant decrease in surface hydrophilicity for the glycerin-painted group (P-value < 0.05). However, the visual and microscopical analysis did not show a prominent distinction in surface quality between the two groups, so there is no noticeable effect on dental stone surface caused by glycerin-modified wax pattern. | ||
