Periodontal disease is prevalent, severe and under recognized in renal failure patients. Prophylaxis and early dental treatment should be intensified in these subjects, and may be of interdisciplinary importance.

Objectives: To describe a modification of the index of clinical consequences of untreated dental caries [pulpal involvement, ulceration, fistula and abscess (PUFA/pufa) index] to pulpal involvement-roots-sepsis (PRS/prs) and to compare the two indices using the example of caries in primary molar teeth in children aged 6-8 years. Subjects andMethods: The study sample included 542 children aged 6-8 years, from five randomly selected schools in the Bialystok District, Poland. The occurrence of clinical consequences of untreated caries in deciduous molars using the pufa and prs indices was evaluated. Data were analysed to express the prevalence, the experience and the distribution of particular pufa and prs codes in the sample population. The differences in layout of the pufa and prs components were expressed. Results: The response rate was 77.6%. The prevalence of the clinical consequences of untreated caries was 40.77%, mean pufa and prs were the same (0.85 ± 1.33). According to the pufa index, the following mean values were obtained: p = 0.79, u = 0.01, f = 0.04 and a = 0.01. For the prs index, the mean values were as follows: p = 0.45, r = 0.35 and s = 0.05. Conclusion: The proposed prs index was a useful epidemiological instrument for the evaluation of the clinical consequences of untreated caries in the surveyed population. The PRS instrument could be a good alternative to the PUFA index.

Evidence has been emerging that hepatocyte growth factor (HGF) -a pluripotential regenerative cytokine -is a key factor in the pathogenesis and progression of periodontal disease, mostly through its over-stimulation of gingival epithelial cell growth and impairment of the regeneration of collagenous structures. We measured the levels of immunoreactive HGF in unstimulated whole mixed saliva from 26 patients referred for treatment of periodontal disease, and from 20 healthy subjects. HGF was detected in all saliva samples from the patients, the concentration ranging from 0.06 to 5.38 ng/ml, with a mean concentration of 1.87 ± 1.32 ng/ml. In healthy individuals, the median salivary HGF level was 0.68 ng/ml (range: 0 -7.33 ng/ml), being almost 3-fold lower (P < 0.0001) than that in the patients. Periodontal parameters in the patients were: gingival index (

Abstract:The incidence of malignant gastrointestinal cancers in Poland has been constantly growing, which has led to an intensification of the search for new markers of the early clinical stage of this disease. The oral cavity, as the first part of the gastrointestinal tract, has a very important role. The oral cavity presents symptoms of both typically stomatological and systemic diseases. Oral cancers, benign or malignant, may originate and grow in any of the tissues of the mouth, and within this small area they may be of varied clinical, histological and biological features. These can be lesions typically observed in the oral cavity, but also characteristic of cases where the symptoms occur both in the mouth and in other body parts. The aim of this study was to present a cytological picture of the oral mucosa in patients with gastric and colon cancer and to compare the cytological picture with that obtained from a group of patients with no cancer, using the Papanicolaou classification and the Bethesda system. The study was conducted in 126 patients treated surgically in the II General and Gastroenterological Surgery Clinic between 2006 and 2008. All patients were divided into two groups based on the type of lesions. In both of the studied groups, more than half of the patients did not present any abnormalities in the mucosa of the mouth, lips and cheeks in the physical examination. None of the patients had erosion, ulceration or lesions typical of leukoplakia or lichen planus. No malignant cells were detected in either of the studied groups, and there were no well-defined lesions found in the oral cavity that would distinguish the patients with gastrointestinal cancer.
