Association between Oral Hygiene Information Sources and Daily Dental and Denture Care Practices in Urban Community-Dwelling Older Adults

The purpose of this cross-sectional study was to explore the sources of daily oral hygiene information among urban community-dwelling older adults in Athens, Greece and associate them with their dental and denture care habits. One hundred and fifty-four older adults (aged 71.7 ± 9.2 years) participated in the study, and their dental status, denture use, daily oral care habits according to current gerodontology recommendations, and oral care information sources were investigated. Daily oral hygiene practices were poor, and a small number of individuals recalled having received oral hygiene advice from a dentist. Only 41.7% of the 139 dentate participants performed toothbrushing with fluoride-based toothpaste at least twice a day, and 35.9% completed regular interdental cleaning. Among 54 denture wearers, 68.5% removed their denture(s) at night, and 54% cleaned them at least twice a day. Oral hygiene information sources included dentists (for approximately half of the participants), media, friends/relatives, non-dental health care providers and dental technicians. Dentate participants who had received oral hygiene information from dentists had a greater probability of brushing their teeth with fluoride toothpaste at least twice a day (p = 0.049, OR = 2.15) and performing regular interdental cleaning (p < 0.001, OR = 29.26). Denture wearers who had received instructions about denture hygiene from dentists were more likely to use a brush and mild soap (p = 0.016, OR = 14.67) and remove their denture(s) at night (p = 0.003, OR = 8.75). Dentists should improve their oral health prevention and promotion strategies for their older patients.
