Effects of dental implant treatment on sleep quality in edentulous older people: A prospective cohort study.

Background Edentulism and sleep disturbances are commonly seen among older people and cause serious negative effects on their daily lives. Edentulism can induce sleep problems by changing maxillo-mandibular anatomy and surrounding soft tissues. The effect of the treatment of complete edentulism on sleep disturbances is not sufficiently understood. The purpose of this cohort study is to detect how different treatment options affect sleep quality, daytime fatigue and sleep disorder breathing in totally edentulous elderly people. Material and Methods Ninety-six individulas (50 male and 46 female) participated in this prospective cohort study. The patients were non-randomly assigned to three groups, fixed implant-supported prostheses (FP), removable implant-supported prostheses (RP) and conventional total prostheses (CP). The Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS) and the STOP-Bang questionnaire were calculated before (T0) and one year after (T1) their prosthetic rehabilitations. Results Although there was no statistically significant difference between groups in terms of mean PSQI (p=0.524), ESS (p=0.410) and STOP-Bang (p=0.697) scores at T0, there was a significant difference between groups in terms of mean PSQI (p=0.011), ESS (p=0.030) and STOP-Bang (p=0.024) scores at T1. The FP group, when compared to CP group was associated with significantly better scores in the PSQI (Δ = -3.399, 95% CI= -4.612 to -2.187), ESS (Δ = -1.663, 95% CI= -3.149 to -0.176) and STOP-Bang (Δ = -0.994, 95% CI= -1.592 to -0.397). Conclusions Within the limitations of this study FP was associated with a positive influence on sleep disturbances. Randomized controlled trials will be needed to provide reliable inference on this association. Key words:Dental implant, edentulism, older people, sleep disturbances.

Health and quality of life differ between community living older people with and without remaining teeth who recently received formal home care: a cross sectional study

ObjectiveTo assess oral health, health, and quality of life (QoL) of care-dependent community-living older people with and without remaining teeth who recently received formal home care.Materials and methodsFor this cross-sectional observational study, community-living older people (≥ 65 years), who recently (< 6 months) received formal home care, were interviewed with validated questionnaires and underwent an oral examination. Oral health, general health, medicines usage, frailty (Groningen Frailty Indicator), cognition (Minimal Mental State Examination), QoL (RAND 36), and oral health-related QoL (Oral Health Impact Profile-14) were assessed.ResultsOne hundred three out of 275 consecutive eligible older people (median age 79 [IQR (Inter Quartile Range) 72–85 years] participated in the study. Thirty-nine patients had remaining teeth and 64 were edentulous. Compared with edentulous older people, older people with remaining teeth scored significantly better on frailty, QoL, physical functioning, and general health. No significant differences were seen in cognition. Dental and periodontal problems were seen in more than half of the patients with remaining teeth. Two third of the edentulous patients did not visit their dentist regularly or at all.ConclusionsCare-dependent home-dwelling older people with remaining teeth generally were less frail, scored better on physical functioning and general health and had better QoL than edentulous older people. Dental and periodontal problems were seen in approximately 50% of the elderly.Clinical relevanceNotwithstanding their common dental problems, frailty, health, and QoL are better in home-dwelling older people with remaining teeth. To maintain this status, we advise not only dentists, but also health care workers and governments, to encourage people to maintain good oral health.

Wearing complete dentures is associated with changes in the three-dimensional shape of the oropharynx in edentulous older people that affect swallowing.

To investigate the effects of wearing complete dentures on pharyngeal shape for swallowing in edentulous older people. In the absence of complete dentures, edentulous older people often lose the occlusal support necessary to position the mandible, which leads to an anterosuperior shift of the mandible during swallowing. This may result in pharyngeal shape changes effecting swallowing function in older people. However, the details of this phenomenon are currently unclear. Participants were 17 older edentulous volunteers. Cone-beam computed tomography imaging was performed with the participant in the seated position and wearing (i) both maxillary and mandibular dentures, (ii) maxillary dentures only and (iii) no dentures. During imaging, participants were instructed to keep their mouth closed to the mandibular position determined in advance during swallowing for each denture-wearing condition. The volume, height and average cross-sectional area of the velopharynx and oropharynx were measured, and the positions of the epiglottis and mandible were recorded. While the vertical height of the oral cavity and pharynx significantly decreased, the volume and average cross-sectional area of the oropharynx significantly increased when dentures were not worn (p<0.01). The absence of dentures caused an anterosuperior shift of the mandible when swallowing and drew the epiglottis forward, resulting in expansion of the oropharynx where the tongue base forms the anterior wall. 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.

Association between number of teeth, edentulism and use of dentures with percentage body fat in south Brazilian community‐dwelling older people

To evaluate if poor oral status was associated with percentage body fat in a representative sample of south Brazilian community-dwelling elderly. Evidence suggests that elders with extensive tooth loss and edentulism present with compromised chewing function, which results in dietary changes. However, few studies have assessed whether poor oral status is associated with percentage body fat in community-dwelling elderly. A random sample of 471 south Brazilians =>60 years of age was evaluated. Measurements included a questionnaire to assess socio-demographic, behavioural, general, and oral health data. Percentage body fat was measured with a Tanita TBF 612 digital scale, which measures foot-to-foot bioelectrical impedance; and oral status assessment, by means of oral examinations assessing the number of teeth and use of dental prostheses. Correlates of risk of inadequate percentage body fat were assessed by means of multinomial logistic regression. Edentulous participants were more likely to be underfat [OR: 3.11 (1.27-7.61)] or overfat/obese [OR: 1.82 (1.05-3.16)]. The present study shows that edentulous older people had higher odds for inadequate percentage body fat. The maintenance of teeth had a crucial role in increasing the chance of having an adequate body fat percentage in the study population.

Influence of Aging and Denture Use on Liquid Swallowing in Healthy Dentulous and Edentulous Older People

To clarify the influence of aging and denture use on swallowing in healthy edentulous people aged 75 and older. A cross-sectional research design was used with participants from Hiroshima University Hospital, Hiroshima University, and Hiroshima City. Participants were examined in Hiroshima University Hospital, Hiroshima, Japan. Thirteen edentulous elderly volunteers (7 male, 6 female; aged 75-86, mean age 81.2) and 19 dentulous elderly volunteers (12 male, 7 female; aged 80-87, mean age 81.2) as a control group participated in this study. Participants reported no clinical symptoms relating to dysphagia, neurological impairments, or degenerative diseases. Participants were asked to swallow a 10-mL barium sulfate solution three times. Edentulous older people were asked to swallow the solution while wearing dentures and with dentures removed. Functional swallowing was recorded on cine-film with a digital subtraction angiography system. Lateral cinefluorography images were obtained from seated subjects. Using a cine-projector, visual images were evaluated qualitatively and quantitatively. No participants exhibited aspiration. The occurrence of laryngeal penetration in the edentulous older people not wearing dentures was the only significant difference (P<.05). Only laryngeal penetration differed significantly between edentulous older people not wearing their dentures and dentulous older people.
