Abstract

The aim of the study was to improve the efficiency of the final stage of orthodontic treatment. The study included 32 patients divided into two groups of 16. Orthodontic treatment was performed using a bracket system active self-ligation straight arc technique with step adjustment anthropometric quantitative evaluation system (The ABO Model Grading System). Centric occlusion and centric relation were analyzed at baseline and after treatment by mandible position indicator MPI (Mandibular Position Indicator). The first group received treatment according to conventional protocol, in the second group braces were readjusted by indirect bonding after ABO anthropometric measurements. The efficiency of orthodontic treatment using ABO system at the late stages of adjustment in the second group was significantly higher than in the first group (p=0.002248; p=0.023431, respectively). MPI analysis in the first group in 10 (62.5%) patients showed mismatch of centric occlusion and centric relation not seen in the second group. In 3 (18.75%) patients of group 2 the difference did not exceed 0.5 mm which was considered normal. Thus, the application of ABO anthropometric system followed by readjustment of incorrectly positioned brackets by indir...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.
