ABSTRACT Background Dentinal sealers (desensitizing agents) are used to protect the pulp from possible injurious effects after tooth preparation and also prevent the penetration of dentinal tubules by bacteria and their products which are currently thought to cause most of the pulpal inflammation under the crowns. Aim The purpose of this study is to determine the efficacy of effect of three different desensitizing agents on retention of crowns cemented with resin-modified glass ionomer cement. Materials and methods Forty freshly extracted maxillary first premolars were notched for retention and the teeth specimens were mounted in autopolymerising resin. The axial height of all the specimens was 4 mm with a 20° angle of convergence. Impressions of the prepared teeth were made, later waxed invested and casted. Thirty teeth were coated with three different desensitizing agents were used in this study: Cavity varnish (Namuvar, Deepti Dental Products), Glutaraldehyde (Gluma- Heraeus Kulzer), Resin (AdheSE, Ivoclar Vivadent). Ten teeth were not coated with desensitizing agents to act as control group. Independent T test used to compare the mean values between groups. Results Tensile strength for average surface area of the groups I, II, III and IV are 0.3759, 0.2375, 0.2411, 0.2348 respectively. The t-test shows ‘p’-value is statistically not significant (p < 0.05) for groups II and III, where as in group IV ‘p’-value is statistically significant (p < 0.01). Conclusion The use of AdheSE/resin-based dentinal sealer showed increase in bond strength of the crowns luted with resin-modified glass ionomer cement when compared with control group. This study advocates the use of resin-based sealer or a glutaraldehyde-based sealer before cementation of the crowns. The cavity varnish, however, reduces the bond strength and is not acceptable.

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 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.

Objective: To evaluate the effect of ethanolic extracts of propolis (EEP) addition in different proportions to glass ionomer cement (GIC) on microleakage and microhardness of GIC. Study design: The cement was divided into four groups: one using the original composition and three with 10%, 25%, and 50% EEP added to the liquid and then manipulated. For microleakage assessment, sixty primary molars were randomly divided into four groups (n=15). Standard Class II cavities were prepared and then filled with EEP in different proportions added to GICs. Microleakage test was performed using a dye penetration method. The data were analyzed using one-way ANOVA and Mann - Whitney U tests (α = 0.05). Disc shaped specimens were prepared from the tested GIC to determine Vickers hardness (VHN). The data were analyzed using one-way ANOVA and post hoc Tukey test (α = 0.05). Results: There were no statistically significant differences between the groups in terms of microleakage (p &gt; 0.05). There were statistically significant differences between the VHN values of groups (p &lt; 0.05). Increasing addition of EEP to GIC statistically significantly increased VHN value of GIC (p &lt; 0.05). Conclusions: The addition of EEP to GIC increased the microhardness of the GIC and did not adversely affect the microleakage. Thus, it might be used during routine dental practice due to its antibacterial properties
