Methods: Thirty-four JIA patients and 34 age- and sex-matched controls not affected by JIA (C) were divided into two groups: with mixed and permanent dentition.

[Juvenile idiopathic arthritis and oral health].

Juvenile idiopathic arthritis (JIA) is the most common autoimmune inflammatory disease of connective tissue in children. It is characterized by progressive joint destruction which causes preserved changes in the musculoskeletal system. The literature describes fully clinical symptoms and radiological images in different subtypes of JIA.

Aim: The aim of the study was to assess the self-reported oral health behaviour of Scandinavian and Polish medical students studying in Poland.

Methods: Three hundred and fifty subjects took part in the questionnaire survey. They were the 4th to 6th year Scandinavian and Polish medical students attending the same medical school.

Polish school nurses' knowledge of the first-aid in tooth avulsion of permanent teeth.

Background: The frequency of dental trauma in schools is secondary only to accidents at home. The aim of this study was to evaluate the knowledge of first aid in the avulsion of permanent teeth presented by Polish school nurses from different areas.

Methods: A cross-sectional study with the use of a structured self-administrative questionnaire was conducted in 2014 on school nurses working in randomly selected Polish provinces.

Caries Assessment Spectrum and Treatment (CAST) Index in the Primary Molars of 6- to 7-year-old Polish Children.

Purpose: To evaluate the caries prevalence and experience in primary molars in Polish 6- to 7-year-old children using the Caries Assessment Spectrum and Treatment index.

Materials And Methods: This cross-sectional study was carried out on a sample of 332 out of 468 invited children (140 6- and 192 7-year-olds). Cluster sampling was used to select the participating schools.

Work-related musculoskeletal disorders among dentists - a questionnaire survey.

Dentists at work are susceptible to the development of health disorders. Bad working habits, repetitive tasks and uncomfortable posture contribute to musculoskeletal disorders (MSDs), stress and loss of production. The paper deals with the assessment of health status among dentists in Poland regarding the symptoms of musculoskeletal pain.

[Restorative treatment of cervical tooth lesions in aspect of biomechanics].

The study describes an appropriate treatment approach to the cervical tooth lesions from biomechanical point of view. The occlusal loading plays an essential role in development and failure of restorative treatment of this kind of defects. Resulting from these loading the stresses and issuing strain accumulate just in cervical region of the teeth and they influence both the marginal adaptation and sealing of the restoration.

[Achievement of endodontics at the edge of the century].

Endodontics is the branch of dentistry which deals with dental pulp pathology and treatment of root canals. There has been noted a significant improvement in this discipline recently, which has made a substantial increase in therapeutical efficiency and made dentists' work easier. It was possible due to dynamic development of new material technologies and clinical procedures.

[Paracervical non-caries defects].

The aim of the study was the description of origin and treatment of paracervical, non-caries defects. Dental plaque is involved in the formation of caries defects, while those of non-caries origin are produced due to the action of mechanical and chemical factors. The treatment consists in wide fluoride prophylaxis (elimination of causes) and in the application of mineralization procedures and restoration of missing dental tissue using modern dental highly-adhesive materials.
