| description | Aim:
This study aims to enhance the scannability of Type III alpha gypsum by incorporating an opacifier and to evaluate its effect on the LSE property.
Setting and Design:
In vitro – Comparative study.
Materials and Methods:
The base powder of Type III alpha gypsum was divided into three groups: Group I (100 g of base powder), Group II (90 g of base powder with 10 g of TiO2), and Group III (80 g of base powder with 20 g of TiO2). The study had two parts: First, scanning the mixtures to determine the best scannable material; second, testing for LSE using a plaster extensometer with 0.01 mm precision. Each group’s scannability was assessed using a Medit lab scanner, and their LSE was measured.
Statistical Analysis Used:
One-way ANOVA with Tukey’s post-hoc test for multiple comparisons.
Results:
Results showed that there was a statistical significance between the three groups. However, there was a decrease in the LSE with an increase in the concentration of the titanium dioxide (TiO2). Group III has shown superior scanning properties compared to the other groups.
Conclusion:
Type III alpha gypsum reinforced with 20% TiO2 as an opacifier has exhibited superior scanning properties and there was a statistically significant decrease in the LSE between all three groups with increase in the concentrations of TiO2. |
