Oral and dental problems affect chewing, swallowing, and speech, disrupting daily life activities, problems with facial and dental aesthetics, disorders in communication, and reducing participation in communities and self-confidence. Therefore, the present study aimed to evaluate oral and dental health and the factors affecting it in the elderly. The present study is a cross-sectional descriptive-analytic study. The research population consisted of 216 elderly people who were included in the study using a stratified random sampling method. A demographic information questionnaire and a questionnaire for assessing the dental and oral health of the elderly (Geriatric Oral Health Assessment Index (GOHAI)) were used to collect information. In addition, the last dental visit, the need for dental treatment, the number of times the mouth is rinsed, and the personal assessment of the individual's oral and dental health status were among the items that were recorded and collected in the form of elderly dental information. After completing the questionnaires, the information was entered into SPSS version 23 and analyzed. In the current study, the mean (SD) score of the elderly oral health questionnaire was 49.51 (8.67), and a statistically significant relationship was found between this variable and the number of times of mouthwash and personal assessment of oral health (P < 0.05). Oral health in the elderly did not show a different status according to educational level, place of residence, gender, employment status, income, smoking, and last dental visit (P > 0.05). The findings of the study showed that the oral health status of the elderly in the study population was relatively low, which could be due to the lack of regular oral hygiene and the unfavorable status that the individual has regarding their oral health assessment.
