EFFECT OF ADDING TIO2 NANOPARTICLES ON THE MECHANICAL PROPERTIES OF HEAT CURED ACRYLIC RESIN BEFORE AND AFTER THERMOCYCLING
Research Abstract
ABSTRACT
Objective:
The aim of this study was to evaluate the effect of different concentrations of titanium dioxide nanoparticles on the mechanical properties of heat polymerized acrylic resin before and after thermocycling. The tested parameters were flexural strength and hardness.
Material and Methods: 120 specimens were prepared according to the specific dimension for each test (flexural strength and micro hardness) and distributed into: - Before thermocycling (control, (TiO2) nanoparticles with concentration (0.1% and 0.2%). - After thermocycling (control, (TiO2) nanoparticles with concentration (0.1% and 0.2%). Thermal cycles were performed in a thermocycling machine consisted of 5000 cycles at 5°C and 55°C. Results: Flexural strength and micro hardness were tested for both groups. The data was collected and statistically analyzed. Both Flexural strength and micro hardness were decreased by adding TiO2 nano particles concentrations.
Conclusion: adding (TiO2) nanoparticles to methyl methacrylate adversely affects the flexural strength and micro hardness before and after thermocycling.

FLOW CYTOMETRIC ANALYSIS IN TONGUE SQUAMOUS CELL CARCINOMA: RELATION TO DISEASE FREE SURVIVAL
Research Abstract
ABSTRACT
DNA ploidy was investigated in 19 formalin fixed-paraffin embedded blocks of tongue squamous cell carcinoma. Single cell suspensions for flow cytometric analysis were prepared according to Hedley, (1989). The DNA ploidy and histogram were calculated and compared with the incidence of tumor recurrence. DNA aneuploidy was observed in 8 (42%) tumors. The mean DNA index was 1.46 with a range of 1.74 to 1.89. Recurrence of the primary lesions was seen in ten cases, distant metastasis found in three cases while only one case showed both local recurrence and distant metastasis. The results indicate positive relationship between aneuploidy and recurrence of tongue squamous cell carcinoma

Immunohistochemical evaluation of PCNA, P53 and survivin in ameloblastoma
Research Abstract
ABSTRACT
The purpose of this study was carried out to examine the expression of PCNA, P53 and survivin in different types of ameloblastoma. The cases of ameloblastoma consisted of solid type tumors and histologic arrangements of different subtypes were observed. In some cases, more than one histologic subtype was identified in the same lesion, and each tumor was categorized according to the predominant cell pattern. PCNA and survivin immunohistochemical expression revealed stronger staining for the follicular ameloblastoma, while for p53 protein the strongest stain was detected in the plexiform type. The results indicated that the ameloblastoma has great proliferative potential, which can contribute to explain its aggressiveness and invasive characteristics
