Yun S, Ogawa N, Izutsu M, Yuki M. The association between social isolation and oral health of community-dwelling older adults-A systematic review. Jpn J Nurs Sci 2023:e12524. [PMID: 36772867 DOI: 10.1111/jjns.12524] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Revised: 12/19/2022] [Accepted: 01/13/2023] [Indexed: 02/12/2023]
Abstract
AIM Social isolation and oral health problems commonly exist in older populations and can influence each other. However, evidence on this bidirectional correlation is scarce. This systematic review aimed to provide a comprehensive overview of literature in which social isolation and oral health were associated with each other separately. METHODS Electronic searches were performed through six databases. Original cross-sectional and longitudinal prospective studies that evaluated the associations between social isolation and oral health as either exposure or outcome were included. RESULTS In total, 282 articles were retrieved. Of these, 10 cross-sectional studies and one longitudinal study were included in the analysis. The level of evidence reported was generally moderate to strong. Most studies found that both stronger objective and perceived social isolation were associated with worse oral health in both directions. The frequency of meeting friends had an inconsistent association with oral health. CONCLUSIONS The results of our systematic review showed a bidirectional association between social isolation and oral health in independent community-dwelling older adults. Both objective and perceived social isolation are associated with oral health. As objective social isolation indicators, quality of social connectedness appears to play a more important role in the association with oral health.

Oral frailty indicators to target major adverse health-related outcomes in older age: a systematic review. GeroScience 2022; 45:663-706. [PMID: 36242694 PMCID: PMC9886742 DOI: 10.1007/s11357-022-00663-8] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Accepted: 09/14/2022] [Indexed: 02/03/2023] Open
Abstract
A well-preserved oral function is key to accomplishing essential daily tasks. However, in geriatric medicine and gerodontology, as age-related physiological decline disrupts several biological systems pathways, achieving this objective may pose a challenge. We aimed to make a systematic review of the existing literature on the relationships between poor oral health indicators contributing to the oral frailty phenotype, defined as an age-related gradual loss of oral function together with a decline in cognitive and physical functions, and a cluster of major adverse health-related outcomes in older age, including mortality, physical frailty, functional disability, quality of life, hospitalization, and falls. Six different electronic databases were consulted by two independent researchers, who found 68 eligible studies published from database inception to September 10, 2022. The risk of bias was evaluated using the National Institutes of Health Quality Assessment Toolkits for Observational Cohort and Cross-Sectional Studies. The study is registered on PROSPERO (CRD42021241075). Eleven different indicators of oral health were found to be related to adverse outcomes, which we grouped into four different categories: oral health status deterioration; decline in oral motor skills; chewing, swallowing, and saliva disorders; and oral pain. Oral health status deterioration, mostly number of teeth, was most frequently associated with all six adverse health-related outcomes, followed by chewing, swallowing, and saliva disorders associated with mortality, physical frailty, functional disability, hospitalization, and falls, then decline in oral motor skills associated with mortality, physical frailty, functional disability, hospitalization, and quality of life, and finally oral pain was associated only with physical frailty. The present findings could help to assess the contribution of each oral health indicator to the development of major adverse health-related outcomes in older age. These have important implications for prevention, given the potential reversibility of all these factors.

Features of the oral microbiome in Japanese elderly people with 20 or more teeth and a non-severe periodontal condition during periodontal maintenance treatment: A cross-sectional study. Front Cell Infect Microbiol 2022; 12:957890. [PMID: 36275030 PMCID: PMC9582337 DOI: 10.3389/fcimb.2022.957890] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Accepted: 09/08/2022] [Indexed: 11/18/2022] Open
Abstract
Introduction The aim of the present study was to characterize the profile and diversity of the oral microbiome of a periodontally non-severe group with ≥20 teeth in comparison with a severe periodontitis group of elderly Japanese people. Methods A total of 50 patients who had ≥20 teeth and aged ≥60 years were recruited, and 34 participants (13 non-severe participants) were analyzed. After oral rinse (saliva after rinsing) sample collection, the V3–V4 regions of the 16S rRNA gene were sequenced to investigate microbiome composition, alpha diversity (Shannon index, Simpson index, richness, and evenness), and beta diversity using principal coordinate analysis (PCoA) based on weighted and unweighted UniFrac distances. A linear discriminant analysis effect size was calculated to identify bacterial species in the periodontally non-severe group. Results The periodontally non-severe group showed lower alpha diversity than that of the severe periodontitis group (p <0.05); however, the beta diversities were not significantly different. A higher relative abundance of four bacterial species (Prevotella nanceiensis, Gemella sanguinis, Fusobacterium periodonticum, and Haemophilus parainfluenzae) was observed in the non-severe group than that in the severe periodontitis group. Conclusion The oral microbiome in elderly Japanese people with ≥20 teeth and a non-severe periodontal condition was characterized by low alpha diversity and the presence of four bacterial species.
