Aim. To determine the prevalence and risk factors for periodontal disease among adult patiens at the Hospital Zalgiris Clinics of Vilnius University and assess the relation of risk factors to periodontal conditions. Designs. 1. To determine the prevalence of gingivitis and periodontitis between males and females in the different age groups. 2. To determine the prevalence of oral hygiene index, dental calculus, smoking between males and females in the different age groups. 3. To evalute the impact of risk factors for periodontal conditions. Methods. Statistical data analysis was performed with the statistical package SPSS 11.0 for Windows and WinPepi (PEPI-for-Windows). Prevalence rate rations (PRR) and 95 % confidence interval (CI) were calculated. Statistical assessment and analysis were performed witch qui-square (χ²) test with value of of p < 0,005 being defined as significant. The medical histories was collected in a randomly sample of 1174 subjects 19-62 years of age the from Hospital Zalgiris Clinics archive. From these medical documents were chosen data of age, sex, diagnose and oral hygiene index (by Green-Vermilion OHI-s index). Smoking history information was obtained from questionnire. Results and conclusions. The prevalence of periodontal disease among adult patiens at the Zalgiris Clinics patients were 81,1%. Periodontal conditions was diagnosed for 314 males and 638 females. Highest prevalence of gingivitis was in groups of ages 18-24 and 25-34. Periodontal status becomes worse with age 35-44 and 45 and over . 56,3 % subjects had good oral hygiene and 20,6 % - poor oral hygiene. Our findings show, that poor oral hygiene increase prevalence of gingivitis(PRR =1,185; χ²=4,376; p<0,036), and periodontitis (PRR =1,386; χ²=14,294; p<0,001) between males and females. The prevalence of dental calculus among individuals were 51,9 %, among females – 33,6% and males – 18,2%. Dental calculus increased prevalence of periodontitis more than 2 times (PRR=2,353; χ²=110,56; p<0,001). Smoking prevalence among individuals was 40,9%, where 22,6% - in females and 1,3% in males groups. Smoking had influence on prevalence of gingivitis (PRR =1,169; χ²=5,168; p=0,023). |
