A Comparison of Teeth Measurements on Plaster and Digital Models.

(1) Background: Modern imaging methods and constantly developing technologies extend the range of diagnostic tools in medicine and in orthodontics. Thanks to them, scientists and doctors can use devices designed to diagnose 3D structures of the human body. The aim of the study was to assess the usefulness of digital orthodontic models as a diagnostic tool in the work of an orthodontist through a comparative analysis of the value of orthodontic measurements made on traditional plaster models and virtual models.

The mechanical strength of orthodontic elastomeric memory chains and plastic chains: An in vitro study.

Background: The loss of physical properties of orthodontic chains has been a topic of discussion among scientists and clinicians, motivating efforts to improve elastic materials and minimize the decrease of force. Orthodontic companies have introduced memory elastomers, which, according to the manufacturers, have improved mechanical properties.

Objectives: The aim of the study was to evaluate the effects of stretching elastomeric chains submerged in 37°C artificial saliva.

[Dental examination integral part of preventive testing head and neck cancers].

In recent years, in Poland and in Europe, we have seen a steady increase in the incidence of malignant tumors of the head and neck. On the basis of national cancer registries, the increase in new cases in the last ten years is over 15% and that worries epidemiologists and the medical community. Taken in Europe prevention programs aimed at reducing new cases.

[The role of the multidisciplinary team in the diagnosis and treatment of patients with laryngeal and hypopharynx cancer].

Introduction: In Poland the annual incidence of cancer of the larynx is about 3,000 cases which accounts 2% of all malignant tumors. Results of treatment of head and neck cancers are still unsatisfactory (five-year survival - 50%). In order to improve the outcome in Greater Poland Cancer Centre in 2010 a multidisciplinary team was created which is involved in the individual qualification of each patient to the best form of therapy.
