Aims: Little is known about the impact of low vision (LV) on dental care in the elderly population. The present study aimed to clarify the oral health status and oral health behavior of older people with LV.
Methods and results: We surveyed community-dwelling older people (age ≥ 65 years, non-LV = 35, LV = 23); and collected data on sex, age, systemic diseases, oral health status, and oral health behavior. Although there was no difference in dental clinic visits within one year, the LV group received significantly lesser oral health instructions by dental hygienists and dentists than the non-LV (60.9% vs 85.7%, P < 0.05) group. Additionally, the LV group was more than twice as aware of the "8020 Campaign," written by the Ministry of Health, Labor and Welfare in Japan than the non-LV group. The non-LV group had higher awareness of thickening agents and denture cleaners, both of which may require visual input. Although we had assumed that LV would lead to poor results for the oral health status, there were no demonstrable differences between both groups.
Conclusion: Older individuals with LV require suitable forms of nonvisual communication to receive oral health instruction and literacy.
