“…Vandenberghe and Jacobs performed a study on human cadaver skulls to investigate the possible effect of tube voltages on accuracy and subjective image quality in periodontal defects using PSP systems using 80, 120 and 160 msec exposure times. There were no statistically significant differences between measurements with different tube voltages and exposure times; besides subjective image quality in detecting lamina dura delineation, trabecular structure depiction, contrast perception and furcation involvement visibility did not differ among observers for varying exposure parameters 13 .…”

SummaryBackground/Aim: The aim of the present study is to evaluate diagnostic accuracy of two generic image receptors with CMOS and PSP sensors for image quality scoring (IQS), burnout incidences (BI) and cervical widths (CW) with regard to four different exposure times.Material and Methods: 43 incisor teeth within 15 paraffin block models were exposed at 4 different exposure times both for the CMOS and PSP groups, and a total number of 120 images were obtained. All images were evaluated by 3 dentomaxillofacial radiologists via 3 different criteria; IQS, BI, CW.Results: Diagnostic quality scorings between groups displayed statistically significant difference for 0,1; 0,125 and 0,16 sec exposure times. PSP group revealed higher IQS. For 0,125 and 0,16 seconds exposure times, PSP group showed higher percentages of BI. Average CW were lower in PSP group. Although no statistically significant difference was found between average CW vs. exposure times in the CMOS group; PSP group revealed significant differences among exposure times. We can state that, the PSP system displayed higher image quality so exposure times can be reduced, alas, the same conclusion is not possible with CMOS system used.Conclusions: Image quality perception is higher in PSP system we used, compared with CMOS system. PSP system display more burnout effects with increasing exposure times, while CMOS system is constant.

“… 16 Furthermore, digital X-ray detector plates provide an excellent spatial resolution perfectly suited for the examination of oral and maxillofacial structures. 17 Another advantage of digital X-ray systems is the almost immediate availability of images. This is especially useful under the above-discussed conditions, where it is often necessary to repeat a shot.…”

PurposeIn the age of X-ray computed tomography (CT) and digital volume tomography (DVT), with their outstanding post-processing capabilities, indications for planar radiography for the study of the dentition of ancient Egyptian mummies may easily be overlooked. In this article, the advantages and limitations of different approaches and projections are discussed for planar oral and maxillofacial radiography using portable digital X-ray equipment during archaeological excavations. Furthermore, recommendations are provided regarding projections and sample positioning in this context.Materials and MethodsA total of 55 specimens, including 19 skeletonized mandibles, 14 skeletonized skulls, 18 separate mummified heads, and 4 partially preserved mummies were imaged using portable digital X-ray equipment in the course of archaeological excavations led by the University of Basel in the Valley of the Kings between 2009 and 2012. Images were evaluated by 2 authors with regard to the visibility of diagnostically relevant dental structures using a 4-point grading system (Likert scale).ResultsOverall, the visibility of diagnostically relevant dental structures was rated highest by both authors on X-ray images acquired using a dental detector. The tube-shift technique in the lateral projections of mandibular dentition achieved the second-best rating, and lateral projections achieved the third-best rating.ConclusionConventional planar digital X-ray imaging, due to its ubiquity, remains an excellent method–and often the only practicable one–for examining the skulls and teeth of ancient Egyptian mummies under field conditions. Radiographic images of excellent diagnostic quality can be obtained, if an appropriate methodology regarding the selected projections and sample placement is followed.

“…Esta modalidade de aquisição de imagens odontológicas digitaisé conhecida como direta, pois faz uso de detectores intraorais do tipo sensor-sólido. Os mais utilizados são os com tecnologia CCD (Charged Coupled Divice) e CMOS (Complementary Metal Oxide Semiconductor) [28]. Estes detectores são conectados diretamente a um computador, através de um cabo, para a transferência dos dados adquiridos instantaneamente, disponíveis em instantes no monitor.…”

Image quality evaluation of eight complementary metal-oxide semiconductor intraoral digital X-ray sensors

Abstract: None of the sensors was considered to generate images of significantly better quality than the other sensors tested. Further research should be directed towards determining the clinical significance of the differences in image quality reported in this study.
