Abstract EN
Back ground: This study was done to assist setting time, solubility of manufactured dental base materials from enamel powder and synthetic hydroxyapatite with or without CO2 lasers treatment.
Materials and Methods : The ratio of the elements of the manufactured base materials and the parameters of CO2 laser (15.92W / cm2 power density and 0.2 seconds exposure time) were detected from the pilot study, the setting time and solubility tests described by British standard specification for zinc polycarboxylate cement was used in this study Results : the results showed that the manufactured base material that contains mixture of enamel powder and hydroxyapatite without CO2 laser treatment has (29.47 ± 2) minutes setting time, and (1.136 ± 0.5)% solubility, while the manufactured base material that contains mixture of enamel powder and hydroxyapatite with CO2 laser treatment has (26.1 ± 3.8) minutes setting time, and(2.66 ± 0.5) % solubility.
While the manufactured base material that contains hydroxyapatite powder with CO2 laser treatment has (16.7±4.5) minutes setting time, and (1.78 ± 0.5) % solubility.
Conclusion : the manufactured base materials that contains enamel powder has longer setting time and the CO2 laser treatment will reduce the setting time of all types of the manufactured base materials, the base materials that contains synthetic hydroxyapatite has higher solubility than other base materials and the CO2 laser treatment will reduce the solubility of the manufactured base materials.
