New sensors for dental X-ray imaging

Autor: J. Andersson, U. Welander, H. Stamatakis, Val O'Shea, R. Irsigler, Kevin M. Smith, C. S. Petersson, M Heuken, Richard Bates, Christer Fröjdh

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 434:18-23

Digital systems for dental X-ray imaging are rapidly replacing conventional film techniques. The major advantages of digital systems are reduced X-ray doses due to increased sensitivity, time savings since no development is needed and reduced use of

Diagnostic performance of the visual caries classification system ICDAS II versus radiography and micro-computed tomography for proximal caries detection: an in vitro study

Autor: H. Stamatakis, Panagiotis Mitropoulos, Christos Rahiotis, Afrodite Kakaboura

Publikováno v: Journal of dentistry. 38(11)

Objectives The purpose of this study was: (a) to compare the visual caries classification system ICDAS II with conventional (CR) and digital radiography (DR) for diagnosis of non-cavitated caries on free proximal surfaces, (b) to examine the potentia

The use of platelet-rich plasma combined with demineralized freeze-dried bone allograft in the treatment of periodontal endosseous defects: A report of two clinical cases

Autor: Markou, N. Pepelassi, E. Kotsovilis, S. Vrotsos, I. Vavouraki, H. Stamatakis, H.C.

Background. On the basis of systematic reviews and randomized controlled trials, the authors provide reports of two cases in which platelet-rich plasma (PRP) combined with demineralized freeze-dried bone allograft (DFDBA) was used to treat periodonta

On the occurrence of a pumice-rich layer in Holocene deposits of western Peloponnesus, Ionian Sea, Greece. A geomorphological and geochemical approach

Autor: Bathrellos, G. Vasilatos, C. Skilodimou, H. Stamatakis, M.

A single, pumice-rich sandy horizon located in Holocene deposits of western Peloponnesus, Ionian Sea, Greece has been newly detected in a littoral belt 250 m wide and more than 3km long. Pumice fragments are hosted in siliceous-cherty sand that overl

Treatment of periodontal endosseous defects with platelet-rich plasma alone or in combination with demineralized freeze-dried bone allograft: A comparative clinical trial

Autor: Markou, N. Pepelassi, E. Vavouraki, H. Stamatakis, H.C. Nikolopoulos, G. Vrotsos, I. Tsiklakis, K.

Background: Platelet-rich plasma (PRP) alone or combined with other regenerative materials was previously studied in human periodontal endosseous defects. There are no sufficient data evaluating to what extent the addition of demineralized freeze-dri

Imaging properties of scintillator coated silicon CCDs

Autor: C. S. Petersson, Christer Fröjdh, U. Welander, H. Stamatakis, Hans-Erik Nilsson, W. Klamra

Publikováno v: 1998 IEEE Nuclear Science Symposium Conference Record. 1998 IEEE Nuclear Science Symposium and Medical Imaging Conference (Cat. No.98CH36255).

Silicon CCDs are widely used for X-ray imaging in dentistry. Due to the low absorption coefficients for X-rays in silicon the CCD is generally coated with a scintillating layer. In this work we have measured the X-ray response from a number of differ
