Glass ionomer cement and resin modified glass ionomer cement are one of the restoration materials that are widely used by dentists. Its presence in the oral cavity causes glass ionomer cement and resin modified glass ionomer cement often in contact with food and beverages such as tangerine juice which can affect the compressive strength. The purpose of this study is to determine the effect of immersion in tangerine juice towards the compressive strength of glass ionomer cement and resin modified glass ionomer. This study was a true experimental with a post test only with control group design. Samples were made from GC Fuji 9 GP and GC Gold Label 2 LC with 36 samples each. Samples were divided into two groups. The first group (18 samples of GC Fuji 9 GP and 18 samples of GC Gold Label 2 LC) was immersed in tangerine juice for 24 hours in an incubator at 37°C. The second group (18 samples of GC Fuji 9 GP and 18 samples of GC Gold Label 2 LC) as a control was immersed in artificial saliva for 24 hours in an incubator at 37°C. The compressive strength was determined using a compression machine. The results showed that the mean compressive strength of glass ionomer cement immersed in tangerine juice was 14,03±0,48 MPa and immersed in artifical saliva was 52,08±0,67 MPa. The mean compressive strength of resin modified glass ionomer cement immersed in tangerine juice was 58,98±0,97 MPa and immersed in artifical saliva was 68,28±0,67 MPa. Data were analyzed with Independent T-test showing the results of p<0.05. The conclusion of this study was that there was an effect of immersion in tangerine juice towards the decreasing of the compressive strength of glass ionomer cement and resin modified glass ionomer cement.

The purpose of this study was to evaluate the compressive strength of two glass ionomer cements, a conventional one (Vitro Fil® - DFL) and a resin-modified material (Vitro Fil LC® - DFL), using two test specimen dimensions: One with 6 mm in height and 4 mm in diameter and the other with 12 mm in height and 6 mm in diameter, according to the ISO 7489:1986 specification and the ANSI/ADA Specification No. 66 for Dental Glass Ionomer Cement, respectively. Ten specimens were fabricated with each material and for each size, in a total of 40 specimens. They were stored in distilled water for 24 hours and then subjected to a compressive strength test in a universal testing machine (EMIC), at a crosshead speed of 0.5 mm/min. The data were statistically analyzed using the Kruskal-Wallis test (5%). Mean compressive strength values (MPa) were: 54.00 ± 6.6 and 105.10 ± 17.3 for the 12 mm x 6 mm sample using Vitro Fil and Vitro Fil LC, respectively, and 46.00 ± 3.8 and 91.10 ± 8.2 for the 6 mm x 4 mm sample using Vitro Fil and Vitro Fil LC, respectively. The resin-modified glass ionomer cement obtained the best results, irrespective of specimen dimensions. For both glass ionomer materials, the 12 mm x 6 mm matrix led to higher compressive strength results than the 6 mm x 4 mm matrix. A higher variability in results was observed when the glass ionomer cements were used in the larger matrices.

The purpose of this study was first to evaluate the elution of 2-hydroxyethyl methacrylate (HEMA) and triethylene glycol dimethacrylate (TEGDMA) monomers from resin-modified glass ionomer cement (RMGIC) and compomers cured with halogen and light-emitting diode (LED) light-curing units (LCUs). The effect of cured materials on the viability of L929 fibroblast cells was also evaluated. One RMGIC (Ketac N100) and two compomers (Dyract Extra and Twinkystar) were tested. Materials were prepared in teflon disks and light-cured with LED or halogen LCUs. The residual monomers of resin materials in solution were identified using high-performance liquid chromatography. The fibroblast cells’ viability was analyzed using MTT assay. The type of LCU did not have a significant effect on the elution of HEMA and TEGDMA. A greater amount of HEMA than TEGMDA was eluted. The amount of TEGDMA eluted from Twinkystar was greater than Dyract Extra (P<0.05) when cured with a halogen LCU. All material-LCU combinations decreased the fibroblast cells’ viability more than the control group (P<0.01), except for Dyract Extra cured with a halogen LCU (P>0.05). Curing with the LED LCU decreased the cells’ viability more than curing with the halogen LCU for compomers. For Ketac N100, the halogen LCU decreased the cells’ viability more than the LED LCU.

Abstract: Dental caries is commonly found among modern people with various age, ranged from children, teenager to adult. This indicates the increasing needs of dental caries care. One of dental caries treatments is filling the tooth by using Glass Ionomer Cement (GIC). GIC is a type of filling material with low resistance against acid. This study aimed to find out whether the submersion time affected the GIC filling. This was an experimental study with a posttest only control group design. Samples were 16 round shaped GIC fillings, divided into two groups: treatment group using 1% acetic acid solution and control group using artificial saliva. Each of both groups were divided into four groups according to the submersion time; 5 minutes, 10 minutes, 15 minutes, and 20 minute. Samples were submersed at 37oC in the incubator. Solubility was measured by using spectrophotometer and data were analyzed statistically by using SPSS. Normality was tested by using the Shapiro-Wilk test. Data were analyzed by using Pearson correlation test. The results showed a p value of >0.05 among treatment. Conclusion: Submersion time did not affect the GIC fillings.Keywords: acetic acid, glass ionomer cement, GIC fillings.Abstrak: Karies gigi merupakan masalah kesehatan yang masih sering dialami oleh masyarakat saat ini dan dijumpai pada berbagai golongan usia, mulai dari anak-anak, remaja dan dewasa. Hal ini menyebabkan kebutuhan perawatan karies gigi semakin meningkat. Salah satu cara perawatan karies gigi yaitu dengan melakukan penumpatan. Glass ionomer cement (GIC) merupakan salah satu bahan tumpatan gigi yang sering digunakan. GIC memiliki daya tahan rendah terhadap kondisi yang asam.

Propolis is a natural resinous substance produced by honey bees. The antimicrobial effects of glass ionomer cement have been shown to improve with the addition of propolis; however its effect on the physicomechanical properties of the cement is not known. Aim: The purpose of this study was to evaluate the compressive strength and solubility of conventional restorative glass ionomer cement following the addition of propolis. Study design: Twenty half cylindrical samples were prepared with conventional restorative glass ionomer cement formed the control group. Another twenty samples were prepared with propolis added to conventional restorative glass ionomer cement formed the experimental group. The compressive strength was assessed using universal testing machine. To assess solubility, the samples were immersed in deionised water at room temperature, for 7 days. The solubility was measured as a difference in the weight of the sample; prior to immersion and following immersion at the end of each day. Results: The control group had a significantly higher mean compressive strength of 146.26 Mpa as compared to the experimental group (135.06 Mpa). The solubility between the groups was significant. Conclusion: In comparison to the control group, incorporation of propolis to conventional restorative glass ionomer cement decreased the compressive strength significantly. The solubility of the cement in the experimental group increased significantly over 7day period as compared to the control group.

The aim of this study was to evaluate the compressive strength of resin-modified glass ionomer cement Fuji II LC and Vitremer, in powder/liquid ratios of 1:1, 1:2 and 1:3, at three periods (24 hours, 7 and 28 days) of storage in distilled water at 37ºC. For each material, P/L ratio and storage time, 5 cylindrical specimens were prepared, with 4mm diameter and 6mm height, in silicon moulds. Specimens were light-cured for 40 seconds at each extremity, removed from the moulds and laterally light-cured (perpendicular to long axis) for 40 seconds, protected as recommended by the manufacturers and immersed for the time tested. The specimens were submitted to compressive strength testing in an Instron machine at a crosshead speed of 1.0mm/min until failure. Data were submitted to ANOVA and Tukey's test (5%), and showed that the compressive strength of resin-modified glass ionomer cement was reduced when P/L ratio was reduced and that the storage in water had little influence on compressive strength.
