Background: GIC as a restorative material has the ability to chemically bond to the structure of teeth and the ability to release fluoride so that it is suitable for use in patients with a high caries risk but has poor mechanical strength. Modification of GIC restorative materials with combination with bioactive materials to obtain benefits such as increasing mechanical properties, antibacterial properties and remineralization potential has been mentioned in some research literature. In this study, Carboxymethyl-chitosan (CMC) is added to the powder phase of conventional GIC to increase the compressive strength. Objective: to analyze the influence of modified GIC with the addition of CMC on compressive strength and surface morphology. Methods: Thirty holes in a cylindrical acrylic mold, each hole has a diameter of 4 mm and thickness of 8 mm, were filled with conventional GIC restorative material (FUJI IX, GC corp, Japan), modified GIC with 5% CMC and 10% CMC added in the powder phase. The samples were divided into 3 groups: control group GIC (n=10), GIC-CMC 5% group (n=10) and GIC-CMC 10% group (n=10). The compressive strength measurement performed with Universal testing machine (Tensilon RTG-10Kn, A&D, Japan), and were calculated according to the following equation: CS= P/(πr2)

Where P is the maximum load and r is the radius of the cylinder-shaped specimen

Statistical analysis was done by One-Way ANOVA and Post hoc Bonferroni (p<0.05). The surface morphology of the material modification of GIC-CMC and control group was observed using the Scanning Electronic Microscope (EVO MA-0, Zeiss, Germany).

Results: There is a significant difference between the GIC-CMC 5% and GIC-CMC 10% modification groups and the control group (One-Way ANOVA; p<0.05). Based on the Post Hoc Bonferroni (p<0.5) test there is a significant difference in compressive strength in SIK-CMC modification materials of 5% and SIK-CMC of 10% with the SIK control group. Modification of SIK with CMC affects morphological changes in the form of reduced porosity and increased fractures along with the addition of CMC percentage.Conclusion: Modification of GIC with CMC addition reduces compressive strength with the lowest average yield at 10% CMC addition. The surface porusity of SIK modification material with the addition of CMC tends to decrease and increase the surface of cracks that widen along with the addition of CMC percentage."

"SIK modifikasi resin dapat mengalami penurunan kekerasan permukaan pada pH kritis rongga mulut 5,5 yang dapat dicegah dengan pemberian ion kalsium dan fosfat. Ion tersebut bersumber dari CPP ACP. Pengaplikasian CPP ACP pada SIK modifikasi resin diketahui mampu mencegah terjadinya penurunan kekerasan permukaan SIK modifikasi resin. Saat ini telah ada penggabungan propolis pada CPP ACP yang bertujuan untuk meningkatkan sifat antibakteri tetapi diketahui penambahan propolis mengurangi pelepasan ion kalsium dan fosfat dari CPP ACP sehingga berpengaruh terhadap kemampuannya dalam melindungi SIK modifikasi resin dari penurunan kekerasan permukaan.
