Master Title

Evaluation of a Novel Zinc-Reinforced Glass Ionomer Cement (Microstructure and Certain Physico-Mechanical Properties)

Master Abstract

English Summary of Master Thesis This study was designed to evaluate and compare microstructure, flexural strength, diametral tensile strength, fluoride release, solubility and water sorption and wear resistance of the new encapsulated zinc reinforced glass ionomer cement to encapsulated conventional and resin modified glass ionomer cements. A total number of one hundred forty four specimens were fabricated. Specimens were divided into three equal main groups (forty eight each), according to type of materials used; conventional glass ionomer (Ketac molar, 3M), resin modified glass ionomer (Photac fil, 3M) and zinc reinforced glass ionomer cements (Chem Fil Rock, Dentsply). For each material: three specimens were randomly selected for scanning electron microscope and EDX evaluation as one day dry specimen, one week dry specimen and one week wet specimen. The remaining forty five specimens of each group were distributed according to testing methods; fifteen specimens for flexural strength test, fifteen specimens for diametral compressive test for tension, then both were further subdivided into three subgroups (five each); according to storage period; one day, one week and one month. Five specimens for fluoride release assessment, five specimens for solubility and water sorption tests and five specimens for wear resistance test. For flexural strength test; bar-shaped specimens were fabricated in split Teflon mold. Specimens were stored in distilled water till the storage period. The test was performed using universal testing machine at a crosshead speed of 1.0 mm/min. For compressive test for tension; disc-shaped specimens were fabricated in split Teflon mold. Specimen were stored in distilled water till the storage period. The test was performed using universal testing machine at a crosshead speed of 0.5 mm/min. For fluoride release assessment; the specimens were stored in 3ml of distilled water and fluoride release was measured using fluoride ion selective electrode daily for the first week then weekly for the two months. For solubility and water sorption tests; the specimens were stored in a desiccator, at (37±1)°C for 24 hours, they were weighed on digital analytical balance (0.0001 g accuracy). This is the initial dry weight (W1). Specimens were then immersed distilled water at (37±1) °C for 1 week in an incubator then weighed one minute after removal from water in the balance (W2). The specimens then dehydrated in a desiccators at (37±1) °C for 24 h and weighed again. This is final dry weight (W3). For wear test; the specimens were stored in distilled water for 14 days at (37±1) °C in an incubator then weighed in digital analytical balance, this is the initial weight (M1). Each specimen subjected to wear testing using TNO-TRIBO Meter Wear testing machine. Test conditions were 0.1 bar wet pressure, the speed of rotation 120 rpm and the time duration for the rotation 10 minutes under constant distilled water irrigation as lubricant. Then specimen was weighed in digital analytical balance and considered as final weight of specimen (M2). The data was collected, recorded and tabulated. Statistical analysis was carried out using SPSS program. One way ANOVA was used to test the effect of group within each time on different measurements. Duncan Post-Hoc Comparisons at p=0.05 was used for means comparison. The results of this study showed that zinc reinforced glass ionomer cement showed less cracks and voids, intermediate flexural strength, highest initial diametral tensile strength and intermediate fluoride release compared to conventional and resin modified glass ionomer cements. Moreover, the highest wear resistance was observed in zinc reinforced GIC. However, the highest solubility and water sorption were observed in zinc reinforced glass ionomer cement followed by resin modified GIC and conventional GIC, respectively. Within the limitation of this study and after analysis of its results, following could be concluded; 1- Zinc reinforced glass ionomer cement is a promising dental filling material. 2- The present of zinc in zinc reinforced glass ionomer cement produced a minimum surface cracks and voids comparable to conventional and resin modified glass ionomer cements. 3- Flouride release from glass ionomer cements is a compositional properties. 4- Although presence of zinc in zinc reinforced glass ionomer cement improved its mechanical properties, yet, a dramatic increase in solubility and water sorption were obvious .

PHD Title

THE EFFECT OF NANODIAMONDS SURFACE DEPOSITION ON CELLULAR ACTIVITY OF 3D-PRINTED POLYCAPROLACTONE SCAFFOLDS FOR BONE TISSUE ENGINEERING (A RANDOMIZED IN-VITRO STUDY)

PHD Abstract

ENGLISH SUMMARY OF PhD Thesis This study was designed to treat 3D-printed polycaprolactone (PCL) scaffolds surface with nanodiamonds deposition, and evaluate its effect on the surface topography, hydrophilicity, degradation, and in-vitro cellular activity compared to untreated 3D-printed PCL scaffolds for bone tissue engineering applications. A total number of 168 PCL scaffold specimens were fabricated by using fused deposition modeling (FDM) technique which is one of 3D printing technology. These scaffolds were equally divided into two main groups according to the surface treatment; Control group (C) consisted of the untreated 3D-printed PCL scaffold specimens and Nanodiamonds group (ND) consisted of nanodiamonds surface deposited 3D-printed PCL scaffold specimens. A number of 54 non-porous scaffold specimens for both groups were fabricated in dimensions of 12mm×12mm×3mm (length.× width × thickness) for morphological, microstructure, surface and chemical characterization by FESEM, Raman spectroscopy, AFM, FTIR, respectively, as well as contact angle measurements by drop shape analyzer, (n=6). Also, 30 porous scaffolds for both groups were fabricated in dimensions of 12mm×12mm×3mm (length × width × thickness) for morphological characterization by FESEM, as well as water uptake and in-vitro degradation measurements by electrical analytical balance (n=6). Regarding in-vitro cellular activity assessment, a number 84 porous scaffold specimens from both groups were prepared with dimensions of 12mm×12mm×6mm (length × width × thickness) for cell adhesion by FESEM, cell viability by MTT assay and osteogenic differentiation by ARS staining at different time intervals (n=6). Statistical significance level was set at p =0.05. The FESEM micrographs revealed that the PCL scaffolds were successfully 3D printed with the exact dimensions of the software design while the Raman spectra confirmed the successful surface deposition of nanodiamonds on the scaffold specimens. The AFM characterization showed the homogeneously distributed nanoscale features of the nanodiamonds across the surfaces of ND group with average surface roughness value of 2.88 nm (±0.821) versus 8.65 nm (±0.855) for C group. Also, the FTIR spectra confirmed the presence of oxygen-containing functional groups on the nanodiamonds surfaces, compared to control group that did not show such groups. Moreover, the ND group revealed a statistically significant smaller contact angle (17.45 degree ±1.34), higher water uptake percentage after 24 hours immersion in PBS (21.56 % ±1.73) and higher degradation rate after six months immersion in PBS (43.92 % ±0.77) compared to C group. Furthermore, clearly enhanced cell adhesion was demonstrated in ND group at different time intervals (day one, day three and day seven). Also, compared to C group, ND group showed a statistically significant higher cell viability percentage of 120.64% (±4.94), 158.35% (±5.40) and 180.67% (±10.59) at all different time intervals; day one, day three and day seven, respectively. Additionally, higher Ca deposits confirming the osteogenic activity of the differentiated BMSCs were observed in ND group compared with C group.
