    4. Effects of Temperature Variations during Sintering of Metal Ceramic Tooth Prostheses Investigated Non-Destructively with Optical Coherence Tomography

      Effects of Temperature Variations during Sintering of Metal Ceramic Tooth Prostheses Investigated Non-Destructively with Optical Coherence Tomography
      Calibration loss of ovens used in sintering metal ceramic prostheses leads to stress and cracks in the material of the prostheses fabricated, and ultimately to failure of the dental treatment. Periodic calibration may not be sufficient to prevent such consequences. Evaluation methods based on firing supplemental control samples are subjective, time-consuming, and rely entirely on the technicians skills. The aim of this study was to propose an alternative procedure for ...

    6. Assessment of dental plaque by optoelectronic methods

      Assessment of dental plaque by optoelectronic methods
      The formation of dental biofilm follows specific mechanisms of initial colonization on the surface, microcolony formation, development of organized three dimensional community structures, and detachment from the surface. The structure of the plaque biofilm might restrict the penetration of antimicrobial agents, while bacteria on a surface grow slowly and display a novel phenotype; the consequence of the latter is a reduced sensitivity to inhibitors. The aim of this study was ...

    7. OCT and shear-force evaluations of zirconia Fixed Partial Prosthesis processed with a conventional CAD/CAM technology

      OCT and shear-force evaluations of zirconia Fixed Partial Prosthesis processed with a conventional CAD/CAM technology
      Introduction. Dental ceramics show better biocompatibility and aesthetic properties in dental constructs with regard to metals. However, they also have an insufficient mechanical stability, as well as low resistance limits due to their fragility. Taking into account these aspects, glass infiltrated with ceramic materials such as alumina (i.e., zirconiareinforced ceramics) is being nowadays considered a better material for full fixed partial prostheses (FPPs) than ceramics: the former has a ...

    11. MicroCT and optical coherence tomography imagistic assessment of the dental roots adhesive

      MicroCT and optical coherence tomography imagistic assessment of the dental roots adhesive
      Several obturation methods are available today to study the 3D filling of the root canal. There are also several methods capable to evaluate the ability to seal apically the root canals. However, the common methods of investigation are invasive; they also lead to the destruction of the samples. If the sectioning differs slightly from the desired area, the investigation is non-conclusive regarding the micro-leakages. Also, although the use of Cone-Beam ...

      Temperature variation in metal ceramic technology analyzed using time domain optical coherence tomography
      The quality of dental prostheses is essential in providing good quality medical services. The metal ceramic technology applied in dentistry implies ceramic sintering inside the dental oven. Every ceramic material requires a special sintering chart which is recommended by the producer. For a regular dental technician it is very difficult to evaluate if the temperature inside the oven remains the same as it is programmed on the sintering chart. Also ...

    15. Imaging of noncarious cervical lesions by means of a fast swept source optical coherence tomography system

      Imaging of noncarious cervical lesions by means of a fast swept source optical coherence tomography system
      Non-carious cervical lesions (NCCL) are defined as the loss of tooth substance at the cemento-enamel junction and are caused by abrasion, erosion and/or occlusal overload. In this paper we proved that our fast swept source OCT system is a valuable tool to track the evolution of NCCL lesions in time. On several extracted bicuspids, four levels of NCCL were artificially created. After every level of induced lesion, OCT scanning ...

  2. About Victor Babes University of Medicine and Pharmacy

    Victor Babes University of Medicine and Pharmacy

    Victor Babes University of Medicine and Pharmacy, Timisoara Romania. What is today's mission of the Romanian school of medicine? It is defined by the key role that it plays in the creation of the sanitary and education reforms. Thus, on one hand, the Medical University has a central role in the efficacy of the health system, whose purpose is improving the health of the population. On the other hand, the preparing of new doctors must integrate the new concept of "medicine without frontiers". Only the University of Medicine can impose as absolutely mandatory the total collaboration between both the teaching and the medical systems, with the commitment of excellence in education, research and caring for the patients. Facing these fundamental requests, the Victor Babes University of Medicine and Pharmacy of Timisoara, lacking an extensive past, has only one chance - looking towards the future. It must continuously offer high European standards in training new doctors, Romanian or foreigners, it must develop valuable biomedical research and intertwined with the educational and research programs, it must promote exemplary clinical services. Considering the difficult conditions of our country, the continuous fulfilling of these objectives can be achieved only by team spirit and by the intergenerational collaboration, by joining the experience and the possibilities of some with the will and the competence of the others.
