Abstract

Background: The prevalence of dental caries in Indonesia in 2018 is 45.3% of the population. Tooth filling is done so that dental caries does not spread further. The restorative material that is commonly used is composite resin. The compressive strength of composite resin is affected by the polymerization process. The surface of the composite resin exposed to air causes the formation of oxygen inhibited layer (OIL). Glycerin acts as a surface coating that can inhibit contact between the composite resin and air so that polymerization can run optimally. Changes in the mechanical properties of composite resins are also influenced by salivary pH and food intake. The acid contained in fermented milk can affect the matrix and filler bonds in composite resins. Further research is needed to determine the compressive strength of nanohybrid composite resins after the application of glycerin in fermented milk immersion. Purpose: To find out whether there is a change in the compressive strength of nanohybrid composite resin after the application of glycerin immersed in fermented milk, also to find out whether the glycerin application and immersion in fermented milk play a role in causing changes of the compressive strength. Methods: Laboratory experimental research with a total sample of 28 which was divided into 4 groups. Composite resin samples were made with a thickness of 3 mm and a diameter of 5 mm, followed by measuring the compressive strength using the Universal Testing Machine. Results: Independent T-Test test showed significantly different results. The compressive strength value of the group with glycerin application was higher than without glycerin application. Meanwhile, the group immersed in fermented milk drinks had lower compressive strength compared to saline immersion. Conclusion: The compressive strength of the nanohybrid composite resin changed after the application of glycerin immersed in fermented milk.

Abstract

Background: Nanofiller composite resin has good mechanical strength also used for restoration that require aesthetics. However, resin composites can experience discoloration resulting in extrinsic or intrinsic factors. To produce perfect polymerization, glycerin can be used as an air-inhibition coating to prevent the formation of Oxygen-Inhibited Layer resulting in a more stable over discoloration. Purpose: To knowing the color change due to the application of glycerin on nanofiller composite resin immersed in turmeric extract solution. Method: It is a laboratory experimental study with a Pre-Test-Post-Test Control Group Design using 28 samples of 3M ESPE Filtek 350XT nanofiller composite resin divided into 4 groups, namely the group with glycerin application and without glycerin application which were soaked in turmeric extract with and saline for 4 days. The color changes were measured using a CHNSpec CS-10 colorimeter before and after immersion. Results: Nanofiller composite resin with turmeric extract immersion without glycerin application had an average discoloration of 90.97 + 23.26 while with glycerin application it had a lower average of 84.37 + 9.24. On the results of the independent sample t-test with a significant level of 5%, it has a value of p = 0.506 > 0.05. Conclusion: Composite resin with glycerin application experienced less color change than composite resin without glycerin application in turmeric extract immersion, but statistically not significant.
