Molecular-level evaluation of selected periodontal pathogens from subgingival regions in canines and humans with periodontal disease.

Dogs commonly serve as a model for various human conditions, including periodontal diseases. The aim of this study was to identify the anaerobic bacteria that colonize the subgingival areas in dogs and humans by using rapid real-time polymerase chain reaction (RT-PCR)-based tests and to compare the results obtained in each species. Bacterial microflora evaluations, both quantitative and qualitative, were performed by applying ready-made tests on twelve dogs and twelve humans. Five samples were collected from each subject's deepest gingival pockets and joined to form a collective sample. The results of the study revealed interspecies similarities in the prevalences of Porphyromonas (P.) gingivalis, Treponema denticola, Tannerella forsythia, and Fusobacterium nucleatum. Red complex bacteria comprised the largest portion of the studied bacterial complexes in all study groups, with P. gingivalis being the most commonly isolated bacterium. The results show similarities in the prevalence of bacterial microflora in dogs and humans. Microbiological analysis of gingival pockets by using rapid real-time PCR-based tests in clinical practice, both veterinary and human, can facilitate the choice of appropriate pharmacological treatment and can provide a basis for subsequent verification of the treatment's effectiveness.

[Facial skeleton traumas in farmers in east-central region of Poland (part I)]. / Urazy czaszki twarzowej powstale podczas pracy w rolnictwie w rejonie srodkowowschodnim Polski (czesc I).

On the base of medical documentation, we presented epidemiological analysis of 215 patients treated for traumas of facial skeleton, which occurred during agricultural tasks. It was concluded that the injuries mentioned above occurred more frequently in males at the age between 18-40. The traumas in this group occurred mainly during use of jig saw or other tools and machinery used in agriculture. However in the female population injuries of facial skeleton resulted mainly from zoogenous trauma and accidental fall downs.

[Maxillo-facial skeletal traumas in farmers in Central-Eastern region of Poland (Part II)]. / Obrazenia czaszki twarzowej spowodowane urazami podczas pracy w rolnictwie w regionie srodkowowschodnim Polski (Czesc II).

In this study based on medical documentation we assessed farming associated traumas of maxillo-facial skeleton, which occurred in the years 1988-1997. 99.1% of patients had fractures of facial bone structures. Mandible fractures were the most frequent (47.4%). Upper facial skeleton was fractured in 37.2% of cases. In 14.4% of cases multi-fractures of facial skeleton were diagnosed. Injuries frequently accompanied the mandible fractures and multi-fractures of facial skeleton.

[Treatment of mandibular fractures in patients at the Department of Oral and Maxillofacial Surgery, University Hospital in Lublin in the years 1988-1997]. / Metody zaopatrzenia zlaman zuchwy u pacjentów leczonych w Klinice Chirurgii Stomatologicznej i Szczekowo-Twarzowej Akademii Medycznej w Lublinie w latach 1988-1997.

Between 1988-1997 in the Department of Dental and Maxillo-facial Surgery of Medical University in Lublin there were applied three types of fixation of mandible bone fracture. Depending on the kind of fracture and teeth condition with 692 (i.e. 60%) patients there was applied preservative treatment and 530 undergone surgery (i.e. 18.1%) and undergone surgical and orthopedic treatment (i.e. 21.9%). Upon analysis of treated population it was concluded, that during period of assessment there occurred significant change of implications for the application of fixation of mandible bone fracture and the leading method became mandible osteosynthesis with intraoral approach.

[Symptoms of temporomandibular joint dysfunction in patients treated for the condylar fractures]. / Objawy dysfunkcji stawu skroniowo-zuchwowego u chorych leczonych z powodu zlaman wyrostka stawowego zuchwy.

124 patients at the age of 7 to 70 years with condylar fractures were treated in the Department of Dental and Maxillo-Facial Surgery in the years 1992-96. The authors carried out control clinical examinations and the radiographic investigations in 42 patients treated conservatively. Late results of treatment were assessed after 5 since post fracture. In the assessment the range of mandible abduction, function of temporomandibular joints, mandibular malposition following movements, occlusal disturbance, dislocation of the central line, and the acoustic symptoms in TMJ.
