Huseyin Avni Balcioglu, DDS, PhD, holds the position of Associate Professor in the Department of Anatomy at Istanbul University Faculty of Dentistry. After receiving his dental degree from Istanbul University Faculty of Dentistry, in 2001, He worked as a Research Assistant in the department of Anatomy, for five years, and completed the PhD program, while he also worked in private dental practice. He took part in administrative activites associated with his roles as a faculty board member. He is currently a member of the Board of Medical Specialties Reporting System Commission of Turkish Ministry of Health. Dr. Balcioglu has lectured as an invited speaker in different symposiums, particularly about TMJ/TMD.
Abnormal in- and out alterations in the anatomical relations of the temporomandibular joint are referred as temporomandibular joint disorders. The incidence of temporomandibular joint disorders is high in the population. Pain is the most common symptom, while few or more symptoms may be involved in the disease process. There are various factors that play a role in disease progress and most frequently it is a combination of them. There are various branches in medical and dental sciences that can have a profound treatment plan which differs from each other in every aspect; one can hardly address an ideal method. The present study aims to underline the need for treatment, as well as the right approach for the treatment.

Aleksandar Dimkov is an Associate Professor and President of Macedonian Association of Pediatric and Preventive Dentistry. He received his DMD from the Saints Cyril and Methodius University of Skopje, Republic of Macedonia (1994) and completed Residency in Pediatric and Preventive Dentistry from the St. Panteleimon University Dental Clinical Center in Skopje (2001). He obtained MSc (2003) and PhD (2011) in the field of Pediatric and Preventive Dentistry from Saints Cyril and Methodius University of Skopje. He was a Visiting Researcher at Medway School of Sciences, University of Greenwich UK (2007-2011). He has published more than 70 national and international publications in the field of pediatric and preventive dentistry as well as in the field of dental materials and microbiology in dentistry.
The glass-ionomer cements, possessing the positive characteristics of fluorine in the processes of re-mineralization and antimicrobial action, distinguish themselves as the most acceptable restorative material. A vast number of studies have established that conventional and resin-modified GICs have the ability for slow and sustainable release of fluorides over long time periods. Because fluorine exhibits antimicrobial effects, glass-ionomer cements could be easily recognized to have an additional very significant characteristic-an antimicrobial effect. In addition to the release of fluoride ions, and in order to improve the antimicrobial characteristics, GICs can potentially be used as templates for the release of other active antimicrobial components. The most used antimicrobial agent to be incorporated in glass-ionomer cements in different concentrations and different percentage ratios is chlorhexidine. Unfortunately, reference data on the incorporation of other antimicrobial components in GICs is very scarce. Although some antimicrobial agents have a confirmed effect in the reduction of the cariogenic salivary flora when used in rinses or toothpastes, the results regarding their incorporation in glass-ionomer cements are still scanty. The main aim of this presentation is the answer to the question, can we obtain antimicrobial GIC-s and improve their characteristics with other antimicrobial components than chlorhexidine or not.

Time : 10:30-11:00
Marginal fit is a very important factor considering the restoration’s long-term success. Adding porcelain to copings may cause distortion and lead to an inadequate fit of all ceramic crowns. The aim of this study was to measure the marginal and internal fit on zirconia all ceramic copings and crowns. Two teeth extracted for periodontal reasons were prepared for zirconia all ceramic crowns. Zirconium copings were made with CAD/CAM zirkonzahn system. On those copings, we applied ceramic layers. Measurements were performed with replica technique threw optic microscope. For each copings or crowns, the specimen was measured at 32 points. All data were statistically analyzed with student t test. The mean marginal gap was 89.7 μm for central zirconia coping and 67.22 μm for the premolar zirconia coping; Internal gap for central zirconia coping was 88.31 μm and 61.9 μm for the premolar zirconia coping. The mean marginal gap after applying ceramic layers was 89.96 μm for central all ceramic crown and 66.9 μm for the premolar all ceramic crown; Internal gap for central all ceramic crown was 88.3 μm and 61.83 μm for premolar all ceramic crown. The zirconia all ceramic zirkonzahn copings and crowns meet the clinical acceptable criteria. There is no significant difference between marginal and internal fit on the zirconium zirkonzahn copings with zirkonzahn all ceramic crowns.
