Image quality in panoramic radiography

Dento Maxillo Facial Radiology
B MolanderH G Gröndahl

Abstract

Because of the increase in panoramic radiography it is important to know if image quality has improved with recent technical developments and if there are differences between the different machines that can justify the difference in price. Six conventional panoramic units and the two panoramic programs (dental and jaw panorama) of the Scanora (Soredex, Orion Corporation Ltd, Helsinki, Finland) multi-modal unit were compared by evaluating the radiographs for subjective image quality and estimating the number of additional intra-oral radiographs necessary for a comprehensive evaluation of the periapical and periodontal bone status. Patients ranging in age from 40 to 60 years with teeth in all four quadrants were selected at random and radiographed with each machine or program. Thirty matching radiographs were selected from our archives in order to evaluate one machine (Orthopantomograph 5, Siemens AG, Bensheim, Germany) which was no longer in use. Seven oral radiologists scored the image quality of between 34 and 36 of the 240 radiographs on a 4-point scale and recorded the additional radiographs needed. The results showed that the mean score for the Scanora dental panorama was significantly higher than mean scores for the other ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
