The BIDM 2014 not only opened the doors to open-discussions and learning for the region but allowed the participants to build their skills and use the oppor- Beirut International Dental Meeting 2014 tunity for networking by up-to- date knowledge and sharing experiences in the application of technology throughout the event. President of Lebanese Dental Association, Prof. Elie Maalouf discussed during the opening ceremony: “With the theme “Planning for the Future” we encourage all Lebanese living in Lebanon and abroad, as well as all Arab and foreign dentists to attend this highly regarded meeting, in an effort to plan for a better future, not just scien- tifically, but culturally and politi- cally.“ Prof. Maalouf further an- nounced, “We should all de- nounce terrorism and extremist behavior. Attending this meeting and especially in this dire time will tell the world that we are strong together and will show them that no matter how hard they try to separate us we will always find a platform to meet. Lebanon is a small country but it has always reflected to the world a sense of modern civilization and openness to all cultures and religions. Lebanon does not tol- erate extremist behavior and will not allow negative media to taint its reputation. Holding ambitious annual dental meet- ings with world renowned inter- national and local speakers will show the world that we are com- peting with first world countries regarding scientific achieve- ments”. > Page 31 BIDM 2014 Opening Ceremony The Exhibition
