Knowledge of periodontal disease and oral hygiene status (OHI-S) to periodontal disease: A cross-sectional study

Periodontitis is considered the second most common dental and oral disease in the world after dental caries. The bacterium in periodontitis is Streptococcus sanguinis and attaches to the teeth and enters the bloodstream, causing inflammation of the walls of blood vessels. After inflammation occurs in the blood vessels, atherosclerosis will occur and then a stroke can occur. This study aims to determine the relationship of knowledge about periodontal disease and dental and oral hygiene status (OHI-S) to periodontal disease. Analytic observational research with cross-sectional design. The study was carried out on patients from the Dental Polyclinic of the Community Health Center, in the Sleman Regency area. The research sample was taken using a proportional random sampling technique, as many as 250 people. The independent variable in this study was knowledge of periodontal disease and OHI-S while the dependent variable was periodontal disease. Collecting data using a questionnaire, examination of the OHI-S index, and the Community Periodontal Index (CPI). Data analysis using Chi-Square. Knowledge of periodontal disease against periodontal disease showed that the p-value was 0.000 (p <0.05) and the OHI-S index for the periodontal disease had a p-value of 0.038 (p <0.05). There is a significant relationship between knowledge about periodontal disease and OHI-S to periodontal disease.
