The Face

Similar to Medicine, digital communication, information processing, and x-ray imaging have changed the face of dentistry. The incorporation of digital systems into medical and dental practice has necessitated development of a standard that allows reliable transmission of information between the devices taking the images, devices storing the images, and devices displaying the images. This standard is termed as DICOM. The following article briefly reviews how DICOM came about, how dentistry is involved, the various elements that are part of the DICOM system, and how DICOM is currently used in dentistry.

Urgency. Replantation of the tooth the expeditious return of an extracted tooth in his hole. Despite the fact that the operation of tooth replantation has been known since the 19th century, to this day in dental practice, this technique is rarely used, although in some cases this type of organ-preserving operations is the only alternative to tooth extraction.Purpose. To analyze the effectiveness of the operation of tooth replantation carried out by the classical method.Materials and methods. Replantation of tooth 1.2 was carried out according to the classical method. Evaluation of optical density of bone tissue surrounding the root apex of the replanting tooth 1.2 was carried out with the use of computed tomography in X-ray output 0,04 mSv according to Hounsfield. The efficiency of the graft mobility was determined using the apparatus Periotest M Siemens (Medizintechnik Gulden). The values of the device from –8.0 to +9.9 correspond to the lack of mobility of the tooth (osteoid type of tooth fixation), from +10.0 to +19.9 — the first degree of mobility, from +20.0 to 29.9 — the second degree, from +30.0 and more — the third degree.Conclusion. 1 year 7 months after the replantation of tooth 1.2 we observed a complete restoration of its functions and the absence of pathological mobility.

PHE and FGDP(UK) co-published Guidance Notes for Dental Practitioners on the Safe Use of X-ray Equipment in 2020 to encompass all relevant information to safely use and maintain radiographic equipment by dental practitioners. This guidance supersedes the first edition, previously published in 2001 by the Department of Health, and there are a number of notable changes that should be highlighted to the dental team. The document is freely available and accessible on the FGDP(UK) website and should be an essential tool to ensure the safety of the dental team, patients and the public. CPD/Clinical Relevance: Members of the dental team must acknowledge the updated guidance notes and look to incorporate these changes into their working routine to ensure good clinical practice.

Success Of Treatment

The introduction of digital x-ray receivers which replaced conventional films was a significant radiographic development that is commonly used in daily dental practice. Dental implant therapy (DIT) is a sought after dental therapeutic intervention and dental radiography is an essential component contributing to the success of treatment. Dental radiographs taken in daily practice are generally conventional two-dimensional images and/or three-dimensional images. Ideally, the choice of radiographic technique should be determined after a thorough clinical examination and comprehensive consideration of the advantages, indications, and drawbacks. Digital three-dimensional modalities that have emerged over the last decade have been incorporated into DIT with the assumption that treatment outcomes will be improved. These modalities are constantly being reassessed and improved but there is a paucity of published information regarding the assessment of variables such as dosages and dimensional accuracy, suggesting that further research in these matters is necessary. This is crucial in order to obtain evidence-based information that may influence future radiographic practices. In this narrative, the authors present the most commonly used dental radiographic modalities currently used in DIT.

Local Cone

The mathematical theory of computed tomography (CT) was proposed by J. Radon in 1917. It was declared that the projection of whole datasets was needed to reconstruct CT images. Therefore, according to J. Radon’s original theory, local cone beam CT (local CBCT) was impossible to achieve. In this paper, I discuss how local CBCT was discovered and developed. Its development required many technical elements, such as a turntable and X-ray television system, for basic experiments such as those on which narrow collimation theory and multifunctional panoramic tomography were based. These experiments endured many failures during development. Now, local CBCT is extremely popular in dental practice because local CBCT has a low radiation dose and high resolution. This paper introduces the technical elements and outlines the important stages during the development of local CBCT in the 1990s.

AbstractUsing a new ID hybrid model of the electron bombardment in flare loops, we study not only the evolution of densities, plasma velocities and temperatures in the loop, but also the temporal and spatial evolution of hard X-ray emission. In the present paper a continuous bombardment by electrons isotropically accelerated at the top of flare loop with a power-law injection distribution function is considered. The computations include the effects of the return-current that reduces significantly the depth of the chromospheric layer which is evaporated. The present modelling is made with superthermal electron parameters corresponding to the classical resistivity regime for an input energy flux of superthermal electrons of 109erg cm−2s−1. It was found that due to the electron bombardment the two chromospheric evaporation waves are generated at both feet of the loop and they propagate up to the top, where they collide and cause temporary density and hard X-ray enhancements.
