AIM:
To evaluate the oral health status in Alzheimer's disease (AD) patients.
MATERIALS AND METHODS:
A descriptive study was performed on 120 AD patients (60 institutionalized in a public institute and 60 attended a daytime center), from September 2013 to January 2014. About 103 subjects formed the control group. The following medical and dental data were collected: dementia severity, pharmacological therapy, physical status (American Society of Anesthesiologists [ASA]), decayed (D), filled (F), and remaining natural teeth (T), DF/T ratio, community periodontal index (CPI), and gingival index (GI). A t-test for independent samples and the Spearman's correlation test were used to evaluate all variables. The significance level was set at 0.05.
RESULTS:
Statistically more AD patients (91.7%) were under pharmacological therapy and their physical status was more severe (ASA 2, ASA 3) compared with control subjects (p < 0.001). Moreover, they presented numbers of D, CPI, and GI significantly higher (p 64 0.005). In the institutionalized subgroup, statistically more moderate and severe AD cases were detected and more patients were edentulous (p < 0.001). Noninstitutionalized patients presented DF/T ratio, CPI, and GI significantly lower (p 64 0.024). A significant weak negative correlation (r = -0.121 to -0.372) between epidemiologic indices and AD severity was observed.
CONCLUSION:
Alzheimer's disease patients show a low oral health status that decreases progressively as the disease severity aggravates. Therefore, further studies are necessary to investigate oral health care interventions for AD patients.
CLINICAL SIGNIFICANCE:
It would be beneficial to introduce trained professional figures in specialized elderly institutions for regular follow-up visits and professional oral hygiene procedures. This task has to be coordinated with the treating physician, family members, and/or caregivers. Knowing that the severity of AD has a negative effect on the oral health status and the type of institutionalization exacerbates it
