          Abstract

          RESUMEN Introducción: En la medida que se incrementa la población de adultos mayores, aumenta la prevalencia, aumenta la prevalencia del deterioro cognitivo. Recientemente, se ha introducido la mala salud oral entre los factores de riesgo potenciales. Objetivo: Determinar la asociación entre la salud oral y el deterioro cognitivo leve en adultos mayores de una comunidad de la provincia de Santiago de Cuba. Métodos: Se realizó un estudio observacional, analítico y retrospectivo, de tipo casos y controles en el período comprendido entre enero y julio del año 2023. La población de estudio estuvo constituida por 257 adultos mayores que vivían en esta comunidad, de los cuales se escogieron 40 casos con diagnóstico de deterioro cognitivo leve, según los criterios de Petersen. Se seleccionaron tres controles por cada caso, 120 adultos mayores con aproximadamente las mismas características que el caso. Se precisó la fuerza de asociación de cada factor de riesgo. Resultados: Se halló una asociación significativa entre padecer deterioro cognitivo leve y presentar un número de 1 a 9 dientes. El dolor oral se presentó con mayor frecuencia en el 72,5 % de los casos. No recordar la última visita al estomatólogo fue causa de deterioro cognitivo leve en el 42,5 %. Cepillarse irregularmente se asoció 4,1 veces más con el riesgo de desarrollar esta afección. Conclusiones : Existe una asociación entre la salud oral y el deterioro cognitivo leve en los adultos mayores. Tener menos dientes y referir dolor oral fueron factores de riesgo importantes para presentar deterioro cognitivo. La visita al estomatólogo y el cepillado de dientes irregular influyeron negativamente en la enfermedad. Sin embargo, el uso de prótesis dentales fue un factor protector para el deterioro cognitivo leve.

          ABSTRACT Introduction: Along with the increase in the population of older adults, the prevalence of cognitive impairment is increasing. Recently, poor oral health has been introduced among potential risk factors. Objective: To determine the association between oral health and mild cognitive impairment in older adults in a community in the province of Santiago de Cuba. Methods: An observational, analytical and retrospective case-control study was carried out from January to July 2023. The study population consisted of 257 older adults living in this community, from which 40 cases were selected with a diagnosis of mild cognitive impairment, according to Petersen's criteria. Three controls were selected for each case, 120 older adults with approximately the same characteristics as the case. The strength of association of each risk factor was determined. Results: A significant association was found between having mild cognitive impairment and having 1 to 9 teeth. Oral pain was more frequent in 72.5% of the cases. Not remembering the last visit to the dentist was a cause of mild cognitive impairment in 42.5 %. Irregular brushing was 4.1 times more associated with the risk of developing this condition. Conclusions: There is an association between oral health and mild cognitive impairment in older adults. Having fewer teeth and reporting oral pain were important risk factors for cognitive impairment. Visiting the dentist and irregular tooth brushing had a negative influence on the disease. However, the use of dental prosthetics was a protective factor for mild cognitive impairment.

          Mild cognitive impairment: a concept in evolution.

          The construct of mild cognitive impairment (MCI) has evolved over the past 10 years since the publication of the new MCI definition at the Key Symposium in 2003, but the core criteria have remained unchanged. The construct has been extensively used worldwide, both in clinical and in research settings, to define the grey area between intact cognitive functioning and clinical dementia. A rich set of data regarding occurrence, risk factors and progression of MCI has been generated. Discrepancies between studies can be mostly explained by differences in the operationalization of the criteria, differences in the setting where the criteria have been applied, selection of subjects and length of follow-up in longitudinal studies. Major controversial issues that remain to be further explored are algorithmic versus clinical classification, reliability of clinical judgment, temporal changes in cognitive performances and predictivity of putative biomarkers. Some suggestions to further develop the MCI construct include the tailoring of the clinical criteria to specific populations and to specific contexts. The addition of biomarkers to the clinical phenotypes is promising but requires deeper investigation. Translation of findings from the specialty clinic to the population setting, although challenging, will enhance uniformity of outcomes. More longitudinal population-based studies on cognitive ageing and MCI need to be performed to clarify all these issues. © 2014 The Association for the Publication of the Journal of Internal Medicine.

              Association between tooth loss and cognitive impairment in community-dwelling older Japanese adults: a 4-year prospective cohort study from the Ohasama study

              Background Numerous prospective studies have investigated the association between the number of remaining teeth and dementia or cognitive decline. However, no agreement has emerged on the association between tooth loss and cognitive impairment, possibly due to past studies differing in target groups and methodologies. We aimed to investigate the association between tooth loss, as evaluated through clinical oral examinations, and the development of cognitive impairment in community-dwelling older adults while considering baseline cognitive function. Methods This 4-year prospective cohort study followed 140 older adults (69.3% female) without cognitive impairment aged ≥65 years (mean age: 70.9 ± 4.3 years) living in the town of Ohasama, Iwate Prefecture, Japan. Cognitive function was evaluated with the Mini-Mental State Examination (MMSE) in baseline and follow-up surveys. Based on a baseline oral examination, the participants were divided into those with 0–9 teeth and those with ≥10 teeth. To investigate the association between tooth loss and cognitive impairment, we applied a multiple logistic regression analysis adjusted for age, sex, hypertension, diabetes, cerebrovascular/cardiovascular disease, hypercholesterolemia, depressive symptoms, body mass index, smoking status, drinking status, duration of education, and baseline MMSE score. Results In the 4 years after the baseline survey, 27 participants (19.3%) developed cognitive impairment (i.e., MMSE scores of ≤24). Multiple logistic regression analysis indicated that participants with 0–9 teeth were more likely to develop cognitive impairment than those with ≥10 teeth were (odds ratio: 3.31; 95% confidence interval: 1.07–10.2). Age, male gender, and baseline MMSE scores were also significantly associated with cognitive impairment. Conclusions Tooth loss was independently associated with the development of cognitive impairment within 4 years among community-dwelling older adults. This finding corroborates the hypothesis that tooth loss may be a predictor or risk factor for cognitive decline.
