Caregiver‐reported dementia as a predictor of oral health among patients receiving home‐visit dental treatment: A retrospective cohort study

Abstract

Objective To assess caregiver‐reported dementia as a risk factor for retained roots, an indicator of poor oral hygiene, among patients receiving home‐visit dental treatment in Japan. Methods The medical records of 231 dentate patients who received home‐visit dental treatment (covered by public medical insurance) for more than 2 years were retrospectively analyzed. The number of teeth and retained roots at the initial and final examinations were obtained from the dental charts, and the “change in the number of retained roots from initial to final examination” was determined. The presence or absence of caregiver‐reported dementia, diabetes, and osteoporosis, as well as the level of long‐term care needed, were used as indicators of general health condition at the initial interview. Multiple regression analyses were conducted in five models that tested the association of independent variables (age, gender, observation period, general health, presence or absence of caregiver‐reported dementia at the initial interview) with changes in the number of retained roots. Results In all models, the presence of caregiver‐reported dementia at the initial interview was significantly associated with the change in the number of retained roots (p < .05). The adjusted coefficient of determination (R2) of model 5, which included all the predetermined independent factors, was .168. Conclusions Caregiver‐reported dementia may be a risk factor for an increase in the number of retained roots among patients who receive home‐visit dental treatment and may serve as an indicator of the need for regular and proactive oral hygiene management.

Dental care of patients with dementia: A survey on practice equipment, training, and dental treatment

“…Overall, respondents rated the incidence of intraoral disease in patients with dementia as significantly increased. This is in agreement with numerous studies (Gao et al, 2020; Yamaguchi et al, 2021; Zeng et al, 2021). Treatment under sedative medication or even general anesthesia in patients with dementia was performed by only a small proportion of the dentists surveyed.…”

Severity of Dementia Is Associated with Increased Periodontal Inflamed Surface Area: Home Visit Survey of People with Cognitive Decline Living in the Community

“…Older people receiving psychiatric care are reported to have higher dental care needs [39]. Participants in this study also had more teeth than other reports of older people with dementia in Japan [40]. Older people with more remaining teeth, subjective chewing and no oral pain are therefore less likely to see a dentist [41].…”

Association of Alzheimer’s disease and periodontitis - a systematic review and meta-analysis of evidence from observational studies

“…The patients with dementia (as in AD) may need home based oral and regular care. The caregiver-reported dementia is a reported risk factor for poor hygiene and prompts a need for dental management in advancing AD patients [35]. On the other hand institutionalized patients (may be done for dementia patients where home care is not possible) with advanced age need planned funds for oral or any healthcare in general [36].…”
