The aim: To study the effect of drug addiction and smoking on the status of periodontal tissues in patients with hepatobiliary pathology. Materials and methods: 58 smokers, 63 drug addicts with hepatobiliary pathology were examined and 92 persons of comparison group (with inflammatory periodontal diseases affected by hepatobiliary pathology, without addiction). Examination of patients included determination of iodine number by Svrakov, S-L and Stallard hygiene indices, PMA index and index PBI.

Results: The results of examination of smokers are worse in patients with cirrhosis than in patients with chronic toxic hepatitis and non-alcoholic steatohepatitis and also the results of these two groups was significantly worse than that of the comparison group (iodine number by Svrakov – 1,4 times and 1,3 times higher, PMA index – 1,7 times and 1,4 times worse, in accordance). The results of the study showed that drug addicts patients are worse values in patients with cirrhosis than in patients with chronic toxic hepatitis and non-alcoholic steatohepatitis and also the results of these two groups was significantly worse than that of the comparison group (iodine number by Svrakov – 1,5 times and 1,4 times higher, PMA index – 1,7 times and 1,5 times worse, in accordance).

Conclusions: Presence of hepatobiliary pathology in smokers and drug addicts increases the risk of periodontal diseases.

 The pathology of the hepatobiliary system significantly affects the state of the organs of the oral cavity. A clinical and index study of the state of periodontal tissues in 122 patients was conducted, which showed the prevalence of periodontal disease in patients with chronic acalculous cholecystitis. The examined patients were divided into groups depending on the treatment method, and the result was evaluated before treatment, directly after treatment and 6 months following treatment. Antidysbiotic hepatoprotector and 2% thiotriazolin ointment were included in the combination therapy. Studies have shown that patients with hepatobiliary pathology have increased likelihood of periodontal diseases, and after treatment, periodontal indicators and the hygiene index are significantly reduced, especially in the group where the proposed scheme was used, and the long-term results were stable for 6 months. 

 Introduction. Liver diseases and pathology of the organs of mouth cavity are interconnected. Smoking, usually increases the manifestations of the underlying disease and affects the course. The aim. To investigate the effect of chronic toxic hepatitis of nicotine-dependent patients and of patients without a bad habit on their periodontal status.

Materials and methods. During the clinical examination of the oral cavity of 86 patients, the depth and incidence of inflammation of the gum were determined using the number of the Svrakov's number (SN); the conditions of hygiene of the oral cavity were estimated using the Silness-Loe (S-l) index; Periodontal Index (PMA) and Bleeding Index (PBI). General histomorphology was studied on drugs stained with hematoxilin-eosin and by the method of Gerlich and van Gieson.

Results. It is established that the indicator of SN had the highest value among patients of group II (2,15±0,13), it was probably (p < 0.05) higher relatively to the group I and comparison group. In the smoking patients with chronic toxic hepatitis, in spinous layer of epithelium was determinanted karyorhexis, karyolysis with the formation of cell debris; basal layer cell proliferation, acanthosis, angiogenesis. We detected damage to collagen and elastic fibers of the periodontal, wich correlated with the intensity and duration of the bad habit. In areas of pronounced alterative changes colonies of bacteria were discovered.

Conclusions. Thus, the results obtained in nicotine-dependent patients with chronic toxic hepatitis visualize damaging effect on the epithelium and weakening of the histohematic barrier of the oral cavity and promotes the reproduction and penetrationof pathogenic microflora into the underlying tissues.

The hair texture changes and hair loss are often the first symptoms of diseases of internal organs. The aim - to study the changes in hair structure, which are reflected in the quality and appearance of hair, to monitor structural changes in the hair and to evaluate the impact of diseases of internal organs in patients in order to improve therapy.Over the course of one year, 40 patients were examined who complained of excessive hair loss and 25 persons, which constituted a control group of apparently healthy people. To determine the structural changes in the root and shaft of the hair, macro- and microscopic examination was used, which was carried out on MBI-3 microscope with an AU-12 binocular attachment (600x magnification). During the examination, the root and the surface of the shaft were carefully examined for cracks or other damage. The pyruvate and pyruvate dehydrogenase tests and antithyroid antibody titer tests were used to detect latent diabetes and autoimmune thyroiditis.
Conclusion: The effect of using lotion and shampoo with dimethylsilanediol in comprehensive treatment was obtained starting from the second month of therapy, which was confirmed by microscopic examination of the hair: hair roots were covered with sheaths, a tile pattern was observed along the entire length of the hair shaft, there were no ridges or grooves. A complete structural restoration of the hair was observed in 70% of patients.
