The faculty of Dentistry organized a visit to the “AEEDC Cairo Education Conference and Exhibition” which was held at the Royal Maxim Palace Kempinski Hotel in the 5th Settlement – Cairo on 12-14 December. The AEEDC Cairo Education Conference and Exhibition is considered one of the highly specialized scientific and educational events dedicated to dentistry professionals in Egypt and the wider MENA region. It also discusses the most important issues and the latest developments in the field. The PUA dental students visited the AEEDC exhibition where they got apprised of the state-of-the-art dental equipment and materials. It is worth mentioning that PUA dental students presented many research papers in this conference, including:

• A research entitled “Safety Measures During Dental Radiology” which was presented by the students Zeinab Alaa Eldin, Jolie Ashraf and Sara Hesham who spoke about the measures should be taken before dental radiology as well as the importance of raising the students’ awareness of these measures. The findings of this research confirmed the necessity of wearing a lead apron that acts as a radiation shield especially for pregnant women to prevent any negative effects of radiation exposure on the embryo.
• A research entitled “Evaluation of Shear Bond Strength of Composite Resin to Dentin vs. Resin-modified Glass Ionomer” which was presented by the students Gina Ahmed, Ahmed Khaled Karkoura and Gawad Sherif. This research was conducted on some removed teeth and the findings proved that the shear bond strength of the composite resin is stronger to the dentin than the resin-modified glass ionomer. This research project was evaluated by a panel of professors in dentistry from Pharos and Alexandria universities.
• A research entitled “The Effects of Natural and Chemical Disinfection on the Quality of Dental Unit Water Lines ” which was presented by the students Sara Alaa Eldin, Abdelrahman Khaled and Somaia Mohamed. A comparison was drawn in this research betweeen the effect of aloe vera and sodium hypochlorite in the purification of water in the dental units. The results showed no statistically significant difference between the two substances in the water purification process, however, it was found that sodium hypochlorite causes calculus in teeth and thus aloe vera is highly recommended as a purifier.
• A research entitled “The Effects of Commercially Available Cosmetics on Oral Tissues” which was presented by the students Pansy Elsayed, Hend Abdel Moniem and Marwan Adel. Albino rats were employed in this experiment while being injected with the lead substance in the cosmetic products. The results showed that this substance caused some inflammation in the oral tissues of the albino rats and thus the research recommended the curtailment of the lead substance in the cosmetic products.

A research entitled “Comparison of Sealing Ability of MTA, Endosequence Bioceramic Root Repair Material and Resin-modified Glass Ionomer (RMGI) in Furcal Perofration Repair (Bacterial Leakage Model)” which was presented by the students Haya Hicham, Yasmin Elsaid and Mohamed Mostafa. This research was conducted on a number of removed teeth which had cavities in their roots and MTA, bioceramic and  glass ionomer materials were injected in them. The findings showed that bioceramic was the most effective material in the sealing ability of root cavities and it managed also to prevent microbial growth. The results also proved that MTA was ranked the second in the effective sealing ability, then came the glass ionomer material.
