Mechanism of enamel damage in the grooves of molars during mastication.

Background: During mastication, molars are subjected to heavy stress. However, a full explanation of the effects of physiological loads on tooth structures is lacking.

Objectives: The study aimed to determine stress in molars and identify the mechanism of enamel damage in the grooves of the teeth during computer-simulated mastication.

Evaluation of dental status and effectiveness of treatment among children and adolescents in the reference groups aged 6, 12, and 18 years from Skierniewice and its region in 2017-2020.

Introduction: Dental caries is a transmissible chronic disease of dental hard tissues. To monitor the course of carious process, age reference groups were designated which are subject to regular dental check-ups. The groups include children aged 6, 12, and 18 years as well as adults at the age of 35-44 and 55-64 years.

Comparative scanning electron microscope analysis of the enamel of permanent human, bovine and porcine teeth.

Background: Bovine and porcine teeth are often used in experiments as substitutes of human teeth.

Objectives: The aim of the present study was to perform a comparative analysis of enamel morphology of permanent human, bovine and porcine teeth under the scanning electron microscope.

Methods: As many as 10 human, 10 bovine, and 10 porcine teeth were studied.

Effect of health promoting behaviours on caries prevalence in children aged 1-3 years from the Skierniewice region.

Background: Health promoting behaviours have a decisive effect on the development and cours of caries at any age.

Objectives: The aim of the study was to investigate the correlation between health promoting behaviours and the state of dentition in children aged 1-3 years by determining the child's age, the cause of the first visit at the dental office and evaluating the relationship between the intensity of dental caries and the frequency of oral hygiene practices as well as the consumption of sweet foods.

Material And Methods: The study was conducted among 204 children aged 1-3 years from the town of Skierniewice and its vicinity, who visited the Dental Clinic at the Ogrodowa Medical Centre in Skierniewice in the years 2019 and 2020.

The influence of tobacco smoking on dental periapical condition in a sample of an adult population of the Łódź region, Poland.

Objectives: Epidemiological studies show that apical periodontitis (AP), alongside tooth decay, is the most common oral disease. The aim of the study was to evaluate the influence of smoking on the prevalence of AP in the population of the Łódź region, Poland.

Material And Methods: The study involved 815 first-time, randomly selected patients reporting to the Central Teaching Hospital of the Medical University of Lodz.
