Abstract

Background: The color of the porcelain surface is the main criterion for achieving perfect aesthetics. A factor that influences the color is the amount of firing of the porcelain. Purpose: To determine the color change of porcelain after repeated firing four times. Method: The research specimens consisted of 6 metals coated with Classic porcelain and 6 metals coated with Noritake porcelain and were subjected to four firing stages, then each stage was fired four times. The color change value was measured using VITA Easyshade. Statistical analysis using ANOVA. Result: The Classic and Noritake groups experienced a significant increase in color change from 1st to 2nd burning and from 1st to 3rd burning with a p-value < 0.05. There is a significant difference in the color change value based on the repetition of porcelain firing with a significance value of 0.000 < 0.05. There is a significant difference in the color change value based on porcelain products with a significant value of 0.020 < 0.05. There is no significant effect between repeated firing on porcelain and porcelain products in affecting the color change value with a significance value of 0.143 > 0.05. Conclusion: Both product groups experienced an increase in color change from firing 1st to 2nd and from firing 1st to 3rd. There was no increase in color change from firing 2nd to firing 3rd. There are significant differences in color change values based on porcelain products and there is no significant effect between repeated firing on porcelain and porcelain products on affecting color change values.

Abstract

Background of the problem: Adolescents with thalassemia often experience dental health problems due to disease complications and treatment. Prevention can be achieved by improving nutritional status and public education about thalassemia. The program activities that can be a solution to these problems are through education. Objectives: This service aims to improve dental health, understanding of the use of dentures, and nutritional status among adolescents with Beta Thalassemia Major in DKI Jakarta. Methods: The methods used in this activity include socialization and counseling on dental health and thalassemia disease, which were attended by 40 adolescents from the Indonesian Thalassemia Foundation in DKI Jakarta. The stages of the activity include the distribution of activity information, the completion of a pre-test questionnaire, presentation of the material, examination, and evaluation session. Results: The post-test results of the community service activity revealed that 57.5% of participants fell into the high knowledge category, 37.5% into the moderate category, and 5.0% into the low category. Conclusion: This indicates that after this activity, there was an increase in understanding regarding efforts to improve nutritional health, the use of dentures, and the nutritional status of adolescents with beta thalassemia. Recommendations or follow-up: The intervention in the form of socialization and counseling has successfully increased the knowledge of nutritional health, dentures, and the nutritional status of adolescents with beta-thalassemia.
