Abstract

Periodontitis is a destructive inflammatory disease of the tooth-supporting tissues and is common among the elderly. World Health Organization (WHO) data indicate that the prevalence of periodontal disease is approximately 19% and increases significantly after the age of 55. Preliminary observations at the Elderly Integrated Health Post (Posyandu Lansia) in Pilang Kidul Village, Kemangsen Hamlet, Sidoarjo City, showed a high prevalence of periodontal problems among the elderly. This study aimed to examine the effect of knowledge on the occurrence of periodontitis in the elderly. A quantitative cross-sectional design was used, involving 50 elderly participants selected through total sampling. Data were collected using a knowledge questionnaire and periodontal examinations based on the Periodontal Disease Index (PDI). Chi-square analysis revealed a significant association between knowledge level and periodontitis (ρ = 0.01; ρ < 0.05). In conclusion, knowledge significantly influences the occurrence of periodontitis among the elderly, emphasizing the need for oral health education programs to reduce periodontal disease in this population.
