EFFECTS OF PROFESSIONAL ORAL HYGIENE AND TEETH WHITENING ON THE MICROELEMENT COMPOSITION OF ENAMEL.

Objective: Aim: The objective of this study is to investigate the impact of professional teeth cleaning and the substances used in modern dentistry for whitening on the microelement composition of tooth enamel.

Patients And Methods: Materials and Methods: To study the morphology and microelement composition of the enamel, scanning electron microscopy was performed using the MiraLM microscope equipped with a Schottky field emission electron gun from Tescan.

Results: Results: A comparative analysis between the areas subjected to mechanical cleaning and those where it was not applied revealed a significant difference in the research results, particularly in carbon, which changed from 25.

MICROBIOLOGICAL ANALYSIS OF ABDOMINAL CAVITY EXUDATE, BLOOD AND AFFECTED TISSUES SAMPLES FROM PATIENTS WITH INTRA-ABDOMINAL ABSCESSES IN COMPLICATED INFECTION OF ABDOMINAL CAVITY.

Objective: The aim: To conduct an analysis of the results of a microbiological examination of biological samples taken from patients with intra-abdominal abscesses.

Patients And Methods: Materials and methods: Material for microbiological examination was collected from 60 patients during surgery and transported to laboratory at the same day. Isolation and identification of microbial pure cultures were performed by standard microbiological methods.

Influence of age, gender characteristics, chronotype on the expression of core clock genes Per1, Clock, Bmal1 and Cry1 in buccal epithelium.

Unlabelled: The purpose of the study is to determine the expression of the core clock genes in buccal epithelial cells of healthy people with different chronotypes.

Materials And Methods: Fourteen healthy volunteers with a healthy periodontium and oral mucosa (7 women and 7 men) were selected for participation in the trial. The buccal epithelium sampling was performed at 07:00 am and 07:00 pm in one day by cytological brush.

THE VALUE OF DENTAL EXAMINATION FOR EARLY DIAGNOSIS OF THE MUSCULOSKELETAL SYSTEM DISEASES.

Objective: The aim: The purpose of the study was to determine the correspondence between the location of the tongue median line and the degree of distortion of the vertebral column at different levels in children with scoliosis.

Patients And Methods: Materials and methods: Totally 56 children (30 girls, 26 boys) aged 11-14 years were examined, with a duration of musculoskeletal disorders 1-3 years. For each participant an oral cavity examination was performed, the position of the middle line of the tongue was determined.

Changes in electromyography test results of patients with pathological abrasion of teeth. the role of anterior teeth in the process of rehabilitation.

Objective: Introduction: Abrasion of teeth significantly affects electromyography results. Analyzing electromyograms of patients who needs complex rehabilitation, it is necessary to note absence of dissociation of the structure, appearance of spontaneous activity in one of the muscles, presence of the prevailing chewing side, appearance of low-amplitude oscillations in biocurrents. The aim: The purpose of this study was to determine the role of anterior teeth in the rehabilitation of patients with increased abrasion.

Review of treatment methods of patients with uncomplicated teeth fractures.

Objective: Introduction: Taking into consideration the high prevalence of dental trauma, the issue dental trauma management in the frontal dentition is relevant, considering the principles of biological, economical feasibility and clinical features of each case. The aim: The purpose of this review article is to draw dentists' attention to the high prevalence of uncomplicated fractures of teeth (without pulp chamber exposure) and to highlight the most effective methods for their managment.

Patients And Methods: Materials and methods: We have processed about 50 scientific sources devoted to the treatment of traumatic lesions of teeth.
