Although the removal of bacteria in the oral cavity is regarded as an important preventive measure against pneumonia, the majority of elderly individuals are rarely provided with oral care-related information. This study examined the usefulness of oral care-related information provision for the elderly by pharmacists working at drugstores. A questionnaire survey was conducted, involving 387 pharmacists working at drugstores and 51 elderly individuals who visited such stores. Oral care-related information had been actively provided by 14.5% of the pharmacists, and 62.5% of all oral care products were being sold as care products. When focusing on the elderly, 70.6% showed interest in oral care, but the proportion of those who had performed self-care to promote such health was limited to 5.9%. After being provided with oral care-information, 97.6% answered "I wish to regularly perform oral self-care", and 86.3% regarded oral care-related information provision by pharmacists as "very useful". The results of this study demonstrate the usefulness of information provision by pharmacists at drugstores to promote oral self-care among the elderly.
