PERBANDINGAN KEBOCORAN MIKRO RESTORASI KELAS II GLASS IONOMER CEMENT DAN CERAMIC REINFORCED GIC
Introduction: GIC is one of the materials used for restorations. The advantages of GIC as a dental restoration are that it has a thermal expansion coefficient similar to a teeth and it can chemically bond with enamel and dentin and the disadvantages are that it is fracture-prone and brittle. CRGIC is a ceramic-reinforced GIC capable of providing hardness properties. Class II restorations are restorations found on the proximal surface of posterior teeth and there is a possibility of micro-leakage due to thin enamel. Objective: To compare micro-leakage of CRGIC and GIC in class II restorations. Methods: This research is an experimental study with a sample size of 24 maxillary premolars with class II cavities. Samples were divided into two groups, group 1 using CRGIC and group 2 using GIC. The samples were treated with manual thermocycling at 5ºC and 55ºC. Samples were immersed in 1% methylene blue solution for 24 hours. Teeth were cut using a separating disc. Microleakage was seen using a USB digital microscope with 100x magnification. The statistical test used was Mann-Whitney alternative test. Results: The average microleakage in groups 1 and 2 were 2.5 and 3.75. Data analysis using the Mann-Whitney alternative test showed a significant difference between the two groups of GIC and CRGIC (p
