Introduction: The assessment of the sleep status of older adults and its relationship to oral health can help determine their well-being and quality of life. In accordance with this purpose, we aimed to evaluate the relationship between oral health and sleep quality in community-dwelling older adults in an urban area.
Materials and methods: The data of this study were taken from the Kayseri Elderly Health Study. The study group was administered a questionnaire form and the Pittsburgh Sleep Quality Index. A specialist dentist examined the oral health conditions (dentures use; caries; deficient, filled, natural teeth numbers; periodontal health) using the Community Periodontal Index and the Oral Health Impact Profile-14 (OHIP-14-TR).
Results: One hundred forty (38.1%) of the study group were female, and 227 (61.9%) were male. When evaluated in terms of oral hygiene, there was a statistically significant difference between those with good sleep quality and poor sleep quality in terms of mechanical interventions such as using toothpaste and an inter-dental brush, and also, OHIP-14-TR was significant. In the binary logistic regression analysis, OHIP-14-TR was found to be a significant risk factor, reflecting only the subjective interpretation of the older adults in terms of oral health-related quality of life (odds ratio: 1.069, 95.0% confidence interval: 1.043-1.096).
Conclusion: This is the first epidemiologic study to examine the relationship between oral health status and sleep quality, in which many oral health indicators are evaluated together in Turkish community-dwelling older adults. OHIP-14-TR may be a useful tool to employ in sleep disorder clinics for older people.
