Prof. Mahmoud Abdel Alim, Vice President of Assiut University for Community Service and Environmental Development, visited the Faculty of Dentistry on Sunday 23 June 2024.
He was welcomed by Prof. Safaa Marzouk Tohami, Dean of the Faculty, Prof. Heba Allah Gamal Rashed, Vice Dean for Community Service and Environmental Development, Prof. Mohamed Badawi Abdel Hamid, Vice Dean for Education and Students, Prof. Mohamed Nahed Attia, Director of the University Dental Hospital, and Mr. Montasser Hussein Ahmed, Moderator of the Faculty.
His Excellency also made a tour inside the Dentistry Hospital, where he praised the level of service provided in the hospital clinics and laboratories and the fee-paying treatment and operations unit.
ABSTRACT
Purpose: This research aimed to compare translucency of lithium disilicate glass ceramic and high translucent monolithic zirconia using different finishing techniques and after being exposed to a corrosive medium.
Materials and Methods: Two main ceramic materials, Lithium Di-silicate (IPS e.max CAD LT A3, C14) and High Translucent Zirconia (HTZ) from DD BioZx2 A3-HT, along with acetic acid as a corrosive agent was employed in this study. Forty ceramic discs(10x12mm) were classified into two groups (20 discs each) according to the type of ceramic used then each group was subdivided into two subgroups (10 discs each) according to the finishing procedure (glazed and polished) then each disc was tested for translucency parameter. All discs were immersed in 4% acetic acid as a corrosive agent to study the effect of aging on translucency of glazed and polished ceramic.
Results: In terms of translucency parameter (TP), both glazed and polished subgroups of E-max samples exhibited statistically no significant difference after corrosion (p-value=0.149). Similar trends were observed in HTZ samples (p-value=0.853). Additionally, when comparing glazed samples between E-max and HTZ, Results showed that there was no statistically significant difference between both materials (E-max/HTZ) p-value=0.067. While for the polished samples there was statistically significant difference between both materials (E-max/HTZ) favoring the superior translucency of polished E-max samples over HTZ ones. p-value=0.029.
Conclusions: The translucency parameter (TP) of the studied materials is not significantly affected by the finishing procedure (mechanical polishing or glazing). But compared to glazing, mechanical polishing produced better translucency outcomes for the examined samples. Also corroded E-max exhibits superior translucency in comparison to HTZ.
ABSTRACT
Purpose: This research aimed to compare lithium disilicate glass ceramic and high translucent monolithic zirconia using different finishing techniques and after being exposed to a corrosive medium.
Materials and Methods: Two main ceramic materials, Lithium Di-silicate (IPS e.max CAD LT A3, C14) and High Translucent Zirconia (HTZ) from DD BioZx2 A3-HT, along with acetic acid as a corrosive agent was employed in this study. Forty ceramic discs(10x12mm) were classified into two groups (20 discs each) according to the type of ceramic used then each group was subdivided into two subgroups (10 discs each) according to the finishing procedure (glazed and polished) each disc was tested for color stability. All discs were immersed in 4% acetic acid as a corrosive agent to study the effect of aging on color stability of glazed and polished ceramic.
Results: In terms of color stability (∆E), both glazed and polished subgroups of E-max samples exhibited statistically significant differences after corrosion, favoring the superior color stability of glazed over polished ones (p-value=0.001). Similar trends were observed in HTZ samples, with glazed samples demonstrating better stability (p-value=0.003). Additionally, when comparing glazed samples between E-max and HTZ, the HTZ group showed significantly better color stability (p-value=0.001). The same pattern was found in polished samples, favoring HTZ over E-max (p-value=0.001).
Conclusions: Corrosion of samples exerted a notable impact on the color stability of the tested Lithium Di-silicate (E-max) and High Translucent Zirconia (HTZ) ceramics, irrespective of the finishing techniques employed. The method of finishing played crucial roles, with glazed HTZ samples demonstrating the least susceptibility to corrosion in terms of color stability.
Prof/ Ahmad Alminshawy, President of Assiut University, inspected the second semester exams for second year ((Assiut Government & National Universities) on June 10th, 2024.
Alminshawy was Accompanied by Prof/ Dr. Nobi Mohamed Hassan (Vice President of Assiut National University for Academic Affairs)
During the inspection, the President emphasized the importance of adhering to the examination regulations for exam supervisors, the need to take all necessary measures to ensure the smooth running of the exams, and the necessity of maintaining the calmness and discipline of the exam halls.
He also polled students about the nature and difficulty of the exams and inquired about any problems they encountered during the exams.
The President was also welcomed by Prof/ Safaa Marzouk Tohami (Dean of the Faculty), Prof/ Heba Allah Gamal El-Din Rashid (Vice Dean of the Faculty for Community Service and Environmental Development), Prof/ Mohamed Badawy Abdel Hamid (Vice Dean of the Faculty for Education and Students), Prof/ Mohamed Nahed Atia (Director of the University Dental Hospital), and Mr. Montasser Hussein Ahmed (Moderator of the Faculty).
