Objective: To compare the effect of 4 remineralizing materials on the incipient artificial carious lesion and its proximal sound enamel when used with fluoride dentifrice. Study Design: Models mimicking proximal contact were made, each of which was placed with an artificial carious specimen in contact with a sound enamel specimen. Each carious specimen was treated with one of four materials: glass ionomer cement (GIC), resin modified glass ionomer cement (RMGIC), 5000 ppm sodium fluoride (F-gel), and casein phosphopeptide amorphous calcium phosphate (CPP-ACP). The GIC and RMGIC specimens were thermocycled. Then all specimens were pH-cycled for 5 days with twice a day soaking in 1,000 ppm NaF dentifrice solution. Specimens were examined by polarized light microscopy and lesion area quantified by image analysis. Results: RMGIC significantly yielded smaller areas of lesion than CPP-ACP and GIC (p<0.05). F-gel reduced more area of lesion than CPP-ACP significantly (p<0.05). In the associated contact, RMGIC significantly reduced the area of lesion better than CPP-ACP (p<0.05). Conclusions: The most effective remineralizing material in reducing the carious lesion areas was RMGIC followed by F-gel, GIC and CPP-ACP. The demineralization inhibitory effects on the associated sound contact enamel followed the same trend.

Background: Class II restoration with zirconia inlay is concerned by numerous studies about the luting coupling between zirconia inlay and teeth. The present study was performed to evaluate the microleakage of Class II zirconia inlayusing two different luting agents and compare to direct restoration using bulk fill composite. Aims: To evaluate the microleakage of Class II restorations using three different techniques. Materials and methods: The study was performed in laboratory with three groups. Each of thirty extracted human teeth was prepared a class II cavity with the same dimensions, then these teeth were randomly divided into 3 groups restored by 3 different approaches. Group 1: zirconia inlay cemented with self-etch resin cement (Multilink N); Group 2: zirconia inlay cemented with resin-modified glass ionomer cement (Fuji Plus); Group 3: direct composite restoration using bulk fill composite(Tetric N-Ceram Bulk Fill). All restorations were subjected to thermal cycling (100 cycles 50C – 55 0C), then immersed to 2% methylene blue solution for 24 hours. The microleakage determined by the extent of dye penetration along the gingival wall was assessed using two methods: quantitative and semi-quantitative method. Results: Among three types of restorations, group 1 demonstrated the significantly lower rate of leakage compared to the others, while group 2 and 3 showed no significant difference. Conclusion: Zirconia inlay restoration cemented with self-etch resin cement has least microleakage degree when compare to class II zirconia inlay restoration cemented with resin-modified glass ionomer cement and direct composite restoration using bulk fill composite. Key words: inlay, zirconia ceramic, class II restoration, microleakage.

AbstractTo investigate the impact of radiotherapy on surface properties of restorative dental materials. A conventional resin composite—CRC (Aura Enamel), a bulk-fill resin composite—BFRC (Aura Bulk-fill), a conventional glass ionomer cement—CGIC (Riva self cure), and a resin-modified glass ionomer cement—RMGIC (Riva light cure) were tested. Forty disc-shaped samples from each material (8 mm diameter × 2 mm thickness) (n = 10) were produced according to manufacturer directions and then stored in water distilled for 24 h. Surface wettability (water contact angle), Vickers microhardness, and micromorphology through scanning electron microscopy (SEM) before and after exposition to ionizing radiation (60 Gy) were obtained. The data were statistically evaluated using the two-way ANOVA and Tukey posthoc test (p < 0.05). Baseline and post-radiation values of contact angles were statistically similar for CRC, BFRC, and RMGIC, whilst post-radiation values of contact angles were statistically lower than baseline ones for CGIC. Exposition to ionizing radiation statistically increased the microhardness of CRC, and statistically decreased the microhardness of CGIC. The surface micromorphology of all materials was changed post-radiation. Exposure to ionizing radiation negatively affected the conventional glass ionomer tested, while did not alter or improved surface properties testing of the resin composites and the resin-modified glass ionomer cement tested.
