Evaluation of the contribution of different groups of teeth to occlusion of patients with symptoms of temporomandibular disorders.

Purpose: The purpose of this study was to analyse the distribution of occlusal forces in the dental arches released during tooth clenching in patients with symptoms of temporomandibular disorders, and to analyse the age and gender structure of the patients in the study group and the control group.

Materials And Method: The study was carried out on a group of 58 patients, of both genders, aged 18-40 years, with full dental arches, who presented for treatment at the Prosthodontics Clinic of the University Dental Clinic in Kraków due to symptoms of temporomandibular disorders. The patients were divided into two groups.

Expanding the range of graphene energy transfer with multilayer graphene.

The interaction between single emitters and graphene in the context of energy transfer has attracted significant attention due to its potential applications in fields such as biophysics and super-resolution microscopy. In this study, we investigate the influence of the number of graphene layers on graphene energy transfer (GET) by placing single dye molecules at defined distances from monolayer, bilayer, and trilayer graphene substrates. We employ DNA origami nanostructures as chemical adapters to position the dye molecules precisely.

The Effect of Brilliant Blue-Based Plaque-Staining Agents on Aesthetic Orthodontic Appliances.

Orthodontic appliances discolour over treatment time, and a yellowish plaque builds up on the contact area of the brackets, adhesive and teeth. Brilliant Blue-based plaque-staining agents (BBPSAs), which increase tooth brushing efficiency, have the potential to support the maintenance of proper oral hygiene during orthodontic treatment. However, they exhibit strong colouring properties, and their impact on the aesthetics of braces remains unclear.

Assessment of Oral Hygiene in Patients Using Fixed and Removable Dentures Treated at the University Dental Clinic in Krakow.

Apart from local lesions, the presence of dental plaque may also have an effect on health, especially in people with general diseases. The aim of this project was to assess the oral hygiene of patients prosthetically treated at the Dental Prosthetics Clinic of the University Dental Clinic in Krakow (Poland) using fixed and removable dentures and to determine the demographic relationships and data related to the education of the respondents. The research material consisted of 120 patients who used fixed (group I) and removable (group II) restorations.

Molecular mechanisms of suberoylanilide hydroxamic acid in the inhibition of TGF-β1-mediated canine corneal fibrosis.

Objective: To investigate molecular mechanisms mediating anti-fibrotic effect of SAHA in the canine cornea using an in vitro model. We hypothesized that SAHA attenuates corneal fibrosis by modulating Smad-dependent and, to a lesser extent, Smad-independent signaling pathways activated by TGF-β1, as well as matrix metalloproteinase (MMP) activity.

Methods: Cultured canine corneal fibroblasts (CCF) were incubated in the presence/absence of TGF-β1 (5 ng/mL) and SAHA (2.
