We recommend that more evidence should be gathered from clinical studies and trials to clarify our diagnostic criteria and management strategies.
Background Oral function deteriorates easily during the acute phase of cerebral stroke. Therefore, oral health care involving a transdisciplinary approach consisting of dental and medical professionals might be important, but has not been studied in detail. Objective This study assessed the oral health status of patients with cerebral stroke in the acute phase, with the aim of elucidating the efficacy of collaborative, transdisciplinary oral health care involving dentists, dental hygienists, nurses and speech therapists. Methods The participants were 115 consecutive acute cerebral stroke patients, who received oral health care while hospitalised at the university hospital. Their oral health status was assessed using the oral health assessment tool (OHAT) on admission and discharge. Results Patients with acute cerebral stroke had high OHAT scores on admission, meaning poor oral health status. The collaborative oral health care resulted in significant decrease of OHAT scores at discharge, indicative of the improvement of oral health status. Multivariate analysis identified OHAT score for tongue, dentures and oral cleanliness on admission as the significant variables associated with poor oral health status at discharge. Conclusions Thus, the oral health of cerebral stroke patients in the acute phase can be improved by implementing transdisciplinary collaboration of medical and dental professionals. Particularly, patients with problems pertaining to the tongue, dentures and oral cleanliness as revealed through OHAT on admission may require more intensive intervention.
Prosthetic treatment with dentures is often required for the elderly who have reduced swallowing function. Therefore, it is important to understand the relationship between denture-wearing and feeding function from the perspective of swallowing. To clarify changes in bolus transport during feeding in elderly edentulous patients with or without complete dentures. Subjects were 15 elderly edentulous volunteers who were treated with maxillary and mandibular complete dentures. The test food was 10 g of minced agar jelly containing barium sulphate with a particle diameter of 4·0-5·6 mm. Lateral videofluoroscopy was performed to assess the position of the leading edge of the bolus, the bolus volume in each area at swallow onset, bolus transit time and the mandibular position during pharyngeal swallowing. There were significant changes between the bolus transport with and without dentures. Without dentures, the leading edge of the bolus at swallow onset fell from the valleculae area to the hypopharynx, and the bolus volume in the hypopharynx increased. Bolus transit time increased in the oral cavity, valleculae and hypopharynx. The mandibular position shifted anterosuperior direction. The results arose owing to anatomical changes in the oral and pharyngeal structure and the following functional changes: poor food manipulation, poor bolus formation and delayed swallowing reflex. Removing dentures in elderly edentulous individuals influences bolus transport during feeding, resulting in the exacerbation of the reduced swallowing reserve capacity that accompanies ageing, and may increase the risk of dysphagia.
<b><i>Introduction:</i></b> Oral frailty describes a trivial decline in the oral function and is considered to be related to frailty. Thus, effective management of oral frailty could prevent or ameliorate physical frailty and the need for care. However, there is a lack of consensus regarding specific interventions for oral frailty. In this cluster-randomized controlled trial, we investigated the effects of a newly developed oral frailty measures program mentored by dentists and dental hygienists for elderly people in a clinical setting. <b><i>Methods:</i></b> Of 3,296 participants included in a field survey, 219 who regularly visited dental clinics and met at least 3 of the following 6 criteria for oral frailty were considered eligible: <20 natural teeth, decreased chewing ability, decreased articulatory oral-motor skills, decreased tongue pressure, and substantial subjective difficulties in eating and swallowing. After applying the inclusion and exclusion criteria, we studied 51 patients in the intervention group (14 men and 37 women; mean age, 78.6 years) and 32 patients in the control group (7 men and 25 women; mean age, 78.0 years). We implemented a 12-week oral frailty measures program only for the intervention group. The program included preparatory oral exercises, mouth-opening training, tongue pressure training, prosodic training, and masticatory training. Primary outcome measures were the chewing ability score, articulatory oral motor skill for /ta/, tongue pressure, subjective difficulty in eating tough foods, and subjective difficulty in swallowing. We compared baseline characteristics using the Mann-Whitney U and χ<sup>2</sup> tests for continuous and categorical variables, respectively. A repeated-measures two-way ANOVA was used to determine the efficacy of independent intervention variables, following the Wilcoxon signed-rank test. The groups (intervention/control) and time (baseline/week 12) were the independent variables. Oral frailty measures were the dependent variables. <b><i>Results:</i></b> Baseline characteristics and assessment results were similar between groups. We observed significant improvements in the intervention group in terms of articulatory oral motor skill for /ta/ and tongue pressure (<i>p <</i> 0.001). No improvements were observed in the control group. <b><i>Discussion/Conclusion:</i></b> Our results suggest that our oral frailty measures program effectively alleviates oral frailty. Future studies are needed to clarify the impact on preventing physical frailty and improving the nutritional status.
Oral feeding and swallowing functions tend to decline with age, and functional problems are exacerbated in older subjects with systemic disorders, including cerebrovascular disorders. 1 The reported prevalence of dysfunction involving oral feeding and swallowing is approximately 30% in community-dwelling elderly subjects 2 and 50% in institutionalised individuals. 3 Many patients admitted to acute care hospitals are affected by dysphagia due to the impact of various systemic disorders.Matsuo et al 4 reported that dysphagia affects more than 25% of inpatients in acute care hospitals. Dysphagia causes aspiration pneumonia, 5 malnutrition, dehydration 6,7 and dietary restrictions. Moreover, AbstractAdequate oral status and functional assessments are important for dysphagia rehabilitation in acute care inpatient settings, especially to establish individualised oral intake. However, the association between food intake levels and oral function has not been elucidated in acute care inpatients. This cross-sectional study clarified the association between oral intake levels and the oral status/function of patients with dysphagia admitted to acute care settings. Admitted patients aged ≥40 years (n = 459; men: 288; mean age: 70.8 ± 12.0) examined at the Department of Dysphagia Rehabilitation at the Iwate Medical University Hospital from April 2007 to March 2014 were included. The oral health status was evaluated by the tongue coating, oral dryness severity, plaque control, posterior occlusal support and a repetitive saliva swallowing test (RSST). Dysphagia severity was determined from the Dysphagia Severity Scale. Oral intake levels were evaluated using the Functional Oral Intake Scale (FOIS) at the time of the initial dental examination (FOIS-I), and they were reevaluated after the revision of levels according to the participants' general condition and oral health status (FOIS-R). Divergence between FOIS-I and FOIS-R was noted in >40% patients. Multiple regression analysis showed significant associations between FOIS-R and consciousness level, activities of daily living, tongue coating, RSST and posterior occlusal support. Patients with dysphagia in acute care settings require detailed assessments of their oral status and function, including swallowing, to determine the most suitable feeding methods and dental interventions to improve oral intake levels. K E Y W O R D S acute care, dentures, dysphagia, oral health, posterior occlusal support, swallowing | 737 FURUYA et Al.since eating is an enjoyable day-to-day experience, dysphagia causes deterioration in the quality of life (QOL). 8Early rehabilitation is effective in dysphagia management. Hence, even in acute care settings, proper dysphagia rehabilitation must be started at an early stage after stabilisation of the patient's general condition. 9 Improvement of the oral status and function is important to conduct dysphagia rehabilitation safely. 10 However, inpatients with dysphagia, particularly elderly patients, have poor oral health and hygiene with a high prevalence ...
Aim Previous studies on the association between intraoral conditions and mortality in community‐dwelling older individuals reported that fewer present teeth (PT) are significant risk factors for mortality. However, how the number of PT relative to the number of functional teeth (FT), including both present and rehabilitated teeth, influences mortality has not been investigated fully. This study examined the impact of the number of FT on mortality among community‐dwelling Japanese older adults. Methods This study was a retrospective, observational and population‐based follow‐up study, which examined 1188 older individuals who participated in an annual geriatric health examination from 2009 to 2015. The average follow‐up period was 1697.0 ± 774.5 days. The primary outcome was all‐cause mortality at follow‐up. The numbers of PT and FT of each participant were counted during an oral examination. In addition, demographics, clinical variables, blood nutrient markers, physical functions and perceived masticatory function were measured. Results Kaplan–Meier analysis, followed by a log‐rank test, revealed that fewer PT (P < 0.001) and FT (P = 0.002) were significantly associated with a reduced survival rate. Cox's proportional hazard analysis indicated that the number of FT, but not the number of PT, was a significant independent mortality risk factor after adjusting for demographics, clinical variables, nutrient markers and physical functioning (P = 0.036, hazard ratio: 2.089). Conclusions Current results suggest that the number of FT more strongly predicts all‐cause mortality than the number of PT among community‐dwelling older adults. Further studies are necessary to consider the confounding of socioeconomic status and disability status. Geriatr Gerontol Int 2020; ••: ••–••.
The absence of dentures results in anatomical changes in oropharyngeal shape that may exacerbate the pharyngeal expansion caused by ageing and reduce the swallowing reserve.
