Background: Very little research has been performed using anthropomorphic juvenile phantoms and Optically Stimulated Luminescent dosimeters to measure the absorbed doses and energy imparted to children during panoramic and cephalometric radiographic examinations of children.rnrnObjectives: To measure juvenile patient radiation dose to the organs of the head and neck during digital panoramic and cephalometric radiography.rnrnMethods & Materials: Two juvenile anthropomorphic CIRS phantoms 5 yr old and 10 yr old were filled with Optically Stimulated Luminescent dosimeters at 21 head and neck organ sites. An Instrumentarium OP100D orthopantogramograph was used to expose the phantoms at 73kVp, 6.4mA and 16.8 s for panoramic imaging and at 85kVp, 12mA, and 17.6s for cephalometric imaging. The effective radiation dose was calculated for all the organs of the head and neck. Organ fractions irradiated were determined from ICRP-89. Organ equivalent doses and overall effective doses (micro Sieverts) were based on either one panoramic view or one cephalometric view and the ICRP-103 tissue weighting factors.rnrnResults: Overall measured organ doses were higher for the 5 yr old than the 10 yr old for both the panoramic and the cephalometric imaging. The highest doses seen were in the glands, extrathoracic airway and the oral mucosa. The organ equivalent dose in micro Sieverts also yielded similar results. The effective dose in micro Sieverts for the 5 yr old was 27.8 (pan) and 6.5 (ceph), while the 10 yr old results were 26.3 (pan and 3.8 (ceph).rnrnConclusions: This was the first study to evaluate radiation exposure to juvenile CIRS phantoms using OSL dot dosimetry in conjunction with panoramic and cephalometric imaging to provide organ equivalent doses and overall effective dose for 10 yr and 5 yr olds based on ICRP-103 tissue weighting factors.

Physiological swallowing and the abandonment of the suction are essential to build a beautiful occlusion.This acquisition occurs spontaneously for 60% of children at age 4 years; sample from which recruits children who will Never need orthodontic treatment.When the child require orthodontic treatment, acquiring a good swallowing will reduce the duration of treatment and ensure the stability of the results. This change in the swallowing program Can be done by cortical or subcortical ways
Hamdan Bin Mohemmed College of Dental Medicine, UAE
Time : 11:00-11:25
Dimitrios Tziafas is Professor of Endodontics in Endodontic Program of Hamdan Bin Mohammed College of Dental Medicine, DHCC Dubai, UAE. He received his DDS and PhD in Aristotle University of Thessaloniki, Greece (AUTH). After post-doc research in Institute Biologie Medicale, Faculte de Medecine, Universite Louis Pasteur, Strasbourg, France, he served as: Professor and Chair of the Department of Endodontology at AUTH and Director of Master Programs in Endodontics in AUTH (1999-2013) and European University College, Dubai (2013-2016), President of IADR – Continental European Division (2006-2008), Chairman of the 42nd IADR-CED meeting and Member of the Research Committee of European Society of Endodontology. He published 8 invited reviews and 50+ research papers in international peer-reviewed scientific journals (Endodontology and Basic Science), a monograph on Reparative Dentinogenesis and textbooks chapters relating to Dentin-Pulp Biology. 25+ lectures as invited keynote speaker and 100+ research presentations in international meetings.
Entering the era of molecular dentistry, novel treatment modalities and biomaterials, able to regenerate craniofacial and oral tissues are designed and tested at preclinical level. Biomedical research, seems to convert progressively the paradigm of traditional dentistry where the lost tooth structure is replaced by an appropriate dental material, into a new regenerative paradigm where the lost tooth structure should be replaced with tooth structure. Numerous experimental approaches support the working hypothesis that the therapeutic control of dentin-pulp complex regeneration is now possible. Among other clinical situations, the clinical challenges in the development of effective therapies in teeth with deep dentinal cavities, extensive loss of crown tooth structure and compromised pulp functions, offer exciting opportunities for the near future. In this presentation the biological insights of the real therapeutic needs in the currently used vital pulp treatment modalities and the newly introduced materials will be reviewed. The most promising molecules-based dentin-pulp complex tissue engineering strategies, and how they can work in a clinically predictable way, will be further discussed.

Keynote: Potential release of in vivo, ex vivo traces metals from metallic medical implants in the human body
Time : 11:25-11:50
Dr. Henryk Matusiewicz is professor of chemistry in the Department of Analytical Chemistry at Poznan University of Technology, Poland. Development and application of novel analytical methodologies: modern methods of sample preparation, development of spectrochemical methods for the quantification of elements, application of analytical methods to problems of environmental, biological and clinical chemistry and inorganic trace and ultratrace analysis, including speciation analysis and fractionation are his main research interests.

He was a postdoctoral research associate at the Department of Chemistry, Colorado State University, USA (1975-1978) and in the Department of Chemistry, University of Massachusetts, USA (1982-1984), International Visiting Scientist at the Elemental Analysis Research Center, US Food and Drug Administration, Cincinnati, USA (1984-1985), Distinguished Visiting Scientist at the National Research Council of Canada, Institute for Environmental Chemistry, Ottawa, Canada (1988-1986, 2011; 3 months each year), Visiting Professor (DAAD) at the University of Hannover, the University of Dortmund and at Max-Planck-Institute für Metallforschung, Dortmund, Germany (1992) and Visiting Professor at the University of Oviedo, Spain (1997).
Metal ion release from metallic materials, e.g. metallic alloys and pure metals, implanted into the human body in dental and orthopedic surgery is becoming a major cause for concern. This lecture provides an overview of both metallic alloys and pure metals used in implant materials in dental surgery. Additionally, a short section is dedicated to important biomaterials and their corrosive behavior in both real solutions and various types of media that model human biological fluids and tissues. The presentation gives an overview of analytical methods, techniques and different approaches applied to the measurement of in vivo, ex vivo trace metals released into body fluids and tissues from patients carrying metal dental implants. Reference levels of ion concentrations in body fluids and tissues that have been determined by a host of studies are presented in this lecture.
