THE STRUCTURE OF VIRAL HEPATITIS IN THE LVIV REGION IN THE YEARS OF 2000- 2010 AND PREVALENCE OF PERIODONTAL PATHOLOGY IN PATIENTS WITH CHRONIC HEPATITIS C

Materials and Methods. A retrospective analysis of 1986 case histories of patients who were treated at the hepatological department of Lviv Regional Clinical Hospital of Infectious Diseases during 2000-2010, and a dental examination of 87 patients aged 20 to 55 years with a history of chronic hepatitis C was carried out. All the patients were treated in Lviv Regional Clinical Hospital of Infectious Diseases. In order to determine the periodontal status, the clinical examination of patients included the index assessment of periodontal tissues and orthopantomography. The analysis of the results of research was carried out by calculating the relative values and their errors. When comparing the proportions, the Fisher's exact test with the Metropolis algorithm was used. Results and Discussion. Based on a retrospective analysis of 1986 case histories a high prevalence of hepatitis C among individuals with viral diseases of the liver was found, which amounted to - 48,3±1,12%, the part with chronic hepatitis C - 40,7±1,1%. The research on periodontal status has shown that 93,1±2,73% of patients with chronic hepatitis C were also diagnosed with periodontal disease with the prevalence of higher degrees of severity of generalized periodontitis. Conclusion. The obtained results demonstrate a high prevalence of chronic hepatitis C in patients and the need to improve the schemes of complex treatment, as well as development of measures aimed at prevention of diseases associated with teeth-retaining structures.
