The article presents two clinical cases of patients with Heerfordt-Waldenström disease demonstrating diagnostic difficulties and the need for holistic treatment approach.

[Ultrastructural changes of human dental hard tissues during orthodontic treatment with fixed appliances].

The aim of the study was to evaluate ultrastructural changes of dental enamel after fixation of orthodontic appliances, initial influence of orthodontic forces and removal of braces. Five intact permanent tooth extracted for orthodontic reasons were included in the experimental study. Scanning probe microscopy was conducted in 4 random enamel points in each tooth (20 points overall) in semi-contact mode with standard 10 nm probes.

[Oral mucosa reaction in patients adapting to removable dentures].

Oral mucosa reaction of prosthetic bed to the removable acrylic dentures was evaluated in 43 patients (12 male and 31 female) aged 56-69 years with partial and full teeth loss in one or both jaws. Patients of the first (control) group (17 patients) were not using additional tools improving fixation of the removable dentures during adaptation period, while patients of the second (main) group (26 patients) used Corega cream for dentures fixation for 30 days follow-up.

[Study on the influence of whitening toothpastes on the nanocomposite material surface].

The influence of whitening toothpastes on the surface of nanocomposite dental restorative materials (24 samples divided in 3 groups according to type of toothpaste used) was studied using optical profilometry. The most significant changes on the surface roughness of the material caused abrasive whitening toothpaste in comparison to enzymes-based paste. Selection and use of whitening toothpastes in patients with dental restorations must be carried out under dentist's supervision.
