Retrieval of silver cones using different techniques

International Endodontic Journal
M Hülsmann

Abstract

Three different techniques of silver cone retrieval were investigated in 41 teeth containing 91 silver cones. The techniques used for retrieval were as follows: (i) hand instrumentation with files, spoon excavators and forceps; (ii) the automated Canal-Finder-System; (iii) ultrasonic devices. In all teeth, these techniques were used in the same sequence, starting with hand instrumentation, followed by the Canal-Finder-System, and ending with ultrasonic devices. Fifty-two of the 91 cones (57 per cent) could be removed with hand instruments. Of the remaining 39 cones, 19 were removed after using the Canal-Finder-System. An additional 10 cones could be removed after the use of ultrasonics. Two cones could only be bypassed by the Canal-Finder-System but were not removed with any of the techniques investigated in this study. Eight silver cones (9 per cent) could neither be bypassed nor removed. It was concluded that silver cone retrieval in more than half the cases could be performed easily with hand instruments, particularly spoon excavators. The automated Canal-Finder-System and ultrasonics proved to be helpful devices in many difficult cases, but did not guarantee success in every case.

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.
