Pengaruh Obat Kumur Beralkohol terhadap Kekasaran Permukaan Semen Ionomer Kaca Konvensional

Surface roughness is one of the important properties to determine the aesthetic and long-term durability of a dental restoration materials such as glass ionomer cements. In the oral cavity, the intervention of food, drink or other materials such as mouthwash can affect the properties of restorative materials. The aim of this study was to evaluate the effect of alcohol containing mouthwash to the surface roughness of conventional glass ionomer cement. This was an experimental laboratory study with time-series design. Samples were conventional glass ionomer cement (Fuji IX, GC, Japan) in disk shaped with 10 mm in diameter and 2 mm thick. Totally 10 samples were made and measured the initial surface roughness. Then the samples were stored in the alcohol containing mouthwash (Listerine® Cool Mint, Johnson & Johnson, Indonesia) for 30 seconds and measured the surface roughness again. The treatment and surface roughness measurements of samples is repeated up to 2 times for data 60 and 90 seconds. Roughness measurements made using profilometer tester (Mitutoyo, Japan). Data were analyzed by one-way ANOVA (p=0,05) post hoc LSD. The results showed the average value of surface roughness of glass ionomer cements early, after soaking 30, 60, and 90 seconds of 0.56 ± 0.11 µm, 0.71 µm ± 0.23, 0.96 ± 0.16 µm and 1.02 ± 0.13 µm. Data analysis shows the difference in surface roughness values were significantly (p <0.05) between groups immersion and significant difference was found between groups of 30 seconds to 60 seconds and a group of 60 seconds to 90 seconds. The conclusion that there is influence of alcoholic mouthwash to the surface roughness of glass ionomer cement and the longer the soaking time with a mouthwash that contains alcohol, the surface roughness of glass ionomer cement will increase.

Objectives: Glass ionomer cements (GICs) are among the most popular dental restorative materials, but their use is limited due to their clinical disadvantages. Many efforts have been made to improve the properties of these materials by adding various fillers. Incorporation of hydroxyapatite (HA) into the GICs is considered to improve the physical properties of restorations, and may prevent treatment failure. This study aimed to evaluate the surface roughness (Ra) of a conventional glass ionomer cement (CGIC), a resin-modified glass ionomer (RMGI) and a Zirconomer with and without micro-hydroxyapatite (µHA). Materials and Methods: This experimental study was conducted on 6 groups (n=10) including CGIC, CGIC + µHA, RMGI, RMGI + µHA, Zirconomer, and Zirconomer + µHA. A total of 60 disc-shaped samples (6 mm × 2 mm) were prepared in plastic molds and were stored in distilled water for 24 h. After polishing of the specimens, their Ra was measured by a profilometer in micrometers (µm). The data were analyzed using two and one-way ANOVA, Tukey's HSD test, and independent t-test. Results: Incorporation of µHA resulted in statistically significant differences in Ra between the study groups (P<0.05). Following the incorporation of µHA, the Ra significantly decreased in CGIC (P=0.013) and Zirconomer (P=0.003). However, addition of µHA to RMGI resulted in a significant increase in its Ra (P<0.001). Conclusion: Addition of µHA decreased the Ra of Zirconomer and CGIC, and increased the surface roughness of RMGI samples.

INTRODUCTION: The aim of adding chlorhexidine (CHX) to glass ionomer cements (GIC) is to improve their antibacterial property, but it may interfere with their bond to dentin. OBJECTIVE: To evaluate the influence of adding chlorhexidine diacetate at different concentrations to a high-viscosity GIC on its bond to sound and artificial caries-affected dentin. MATERIAL AND METHOD: Eighty human third molars were used, on which an area of dentin was exposed on the occlusal surface. Half of the specimens were kept sound and the other half were subjected to artificially induced caries. CHX was mixed with GIC powder at 0.5%, 1% and 2% (w/w). GIC without CHX was used as control. On each dentin surface a specimen measuring 1 mm in diameter and 1 mm high was made. The samples were kept at 37 °C and 100% humidity for 24 hours and subject to microshear testing. The results were analyzed using Kruskal-Wallis and Mann Whitney tests (α=0.05). RESULT: There was no significant difference between bond strength of sound and caries-affected dentin (p>0.05). For both substrate conditions, groups GIC, GIC+0.5% CHX and GIC+1% CHX showed statistically similar bond strength (p>0.05), and higher than that of GIC+2% CHX (p<0.025). Cohesive and mixed failures were predominant in all groups. CONCLUSION: The addition of 0.5% and 1% chlorhexidine did not result in negative changes in the bond strength of GIC to caries-affected and sound dentin.

This article describes the properties, advances and shortcomings of glass-ionomer cement as a restorative material. The adhesion of glass-ionomer to tooth structure is less technique sensitive than composite resins and its quality increases with time. Therefore glass-ionomer might turn out to the more reliable restorative material in minimal invasive dentistry based on adhesive techniques.

This study evaluated, in vitro, marginal microleakage in class II restorations confected with the glass ionomer cement Vitremer and with the composite resins Ariston pHc and P-60. The aims of the study were to assess the effect of thermocycling on those materials and to evaluate two methods utilized in the analysis of dye penetration. Sixty premolars divided in three groups were utilized; the teeth had proximal cavities whose cervical walls were located 1 mm below the cementoenamel junction. Half of the test specimens from each group underwent thermocycling; the other half remained in deionized water, at 37ºC. The specimens were immersed, for 24 hours, in a basic 0.5% fuchsin solution at 37ºC. For the analysis of microleakage, the specimens were sectioned in a mesio-distal direction, and the observation was carried out with the software Imagetools. The results were evaluated through the 2-way ANOVA and through the Tukey’s test. All groups presented marginal microleakage. The smallest values were obtained with Vitremer, followed by those obtained with the composite resins P-60 and Ariston pHc. There was no statistically significant difference caused by thermocycling, and the method of maximum infiltration was the best for detecting the extension of microleakage.

Objective: To evaluate the marginal fit and microleakage of monolithic zirconia crowns cemented with bioactive cement (Ceramir) compared to that cemented with glass ionomer cement and to evaluate the effect of thermocycling on marginal fit. Materials and methods: Twenty sound human molar teeth were prepared to receive a monolithic zirconia crowns. Teeth were divided randomly into two equal groups according to the type of luting cement. Group I: glass ionomer cement and group II: Ceramir cement. After cementation, the vertical marginal gap was assessed by using stereomicroscope before and after thermocycling. Twenty equidistant measurement points were taken for each crown. Leakage assessment was carried out using Fuchsin dye penetration followed by digital photography under a stereomicroscope. Data were analyzed by Mann-Whitney U test to compare between the two luting cements. Wilcoxon signed-rank test was used to evaluate the effect of thermocycling on the marginal fit (P ≤ 0.05) Results: Whether before or after thermocycling, the results showed no significant difference between the marginal gap values of the two tested groups. For both groups, there was a significant increase in marginal gap values after thermocycling. Also, there was no significant difference between leakage scores of the two tested groups. Conclusions: Similarity in the physical properties and chemical composition of the two cements result in a non- significant effect on the vertical marginal fit and the extent of microleakage of translucent zirconia crowns. Thermocycling had a negative impact on the vertical marginal gap of the two tested luting agents.

Abstract In this study the top and bottom surface hardness of two polyacid-modified composite resins (PMCRs), one resin-modified glass ionomer cement (RMGIC), and one composite resin were evaluated. The affect of water storage on their hardness was also investigated. The study was conducted using four different groups, each having five specimens obtained from fiberglass die molds with a diameter of 5 mm and a height of 2 mm. Measurements were made on the top and bottom surface of each specimen and recorded after 24 hours and again at 60 days. All tested materials showed different hardness values, and the values of top surfaces of the specimens were found to be higher than the bottom surface in all test groups. There was no statistical difference in the Vickers hardness (HV) values when the test specimens were kept in water storage. In conclusion Hytac displayed microhardness values higher than Vitremer and Dyract. We found the order of HV values to be Surfil > Hytac > Dyract > Vitremer, respectively. Vitremer presented the lowest microhardness level and Surfil the highest. Citation Bayindir YZ, Yildiz M.
