Sleep Breath 2024:10.1007/s11325-024-03139-5. [PMID: 39302516 DOI: 10.1007/s11325-024-03139-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2024] [Revised: 07/24/2024] [Accepted: 08/07/2024] [Indexed: 09/22/2024]
Abstract
PURPOSE This study aimed to clarify the relationship between the oral environment and psychological factors as predictor variables of sleep quality, in addition to inferring the relevant mechanisms of sleep and temporomandibular disorders (TMDs) by analyzing the relationship between TMDs and stress. METHODS This cross-sectional study analyzed data from 1,032 participants, comprising 420 men and 612 women, from the 2017 Iwaki Health Promotion Project using multiple regression analysis. The primary endpoints were the scores of each item in the Pittsburgh Sleep Quality Index (PSQI) and its sum. Predictor variables included the number of teeth; TMDs; stress, assessed using the World Health Organization-5 (WHO-5); sleep bruxism; and oral health-related quality of life, assessed using the oral health impact profile-14 (OHIP14). The confounding factors included age, body mass index, and alcohol intake. RESULTS Multiple regression analysis revealed that TMDs (β value = 0.293, p = 0.034) and stress (β value = 1.3, p < 0.001) were significantly correlated with the PSQI total score. In addition, TMDs were significantly correlated with stress (β value = 0.076, p = 0.007). CONCLUSION The significant relationship between sleep and TMDs suggests that mental stress contributes to the development sleep disorders and consequently is associated with the development of TMD symptoms.

[PMID: 38627762 PMCID: PMC11020950 DOI: 10.1186/s12903-024-04214-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Accepted: 04/01/2024] [Indexed: 04/19/2024] Open
Abstract
BACKGROUND This cross-sectional study aimed to identify factors associated with age-related changes in masticatory performance (MP) and oral diadochokinesis (ODK) and to provide normal values in healthy old adults for the diagnosis of oral frailty. METHODS A total of 385 participants were divided into three age groups (Gr1-3): 20-64 years, 65-74 years, and ≥ 75 years. To investigate tongue-lip motor function, ODK was assessed as the number of repetitions of the monosyllables /pa/ta/ka/. Four questionnaires were used to assess subjective masticatory ability, cognitive ability, and psychological status. MP, bite force, and occlusal area were tested to assess dynamic objective masticatory function, and the number of remaining teeth and functional tooth pairs were determined to assess static objective masticatory function. Handgrip strength (HG), oral dryness, and tongue pressure (TP) were assessed to identify influencing factors. Intergroup differences were evaluated by ANOVA and the Kruskal‒Wallis test, and correlations between ODK and orofacial factors were evaluated. RESULTS This study revealed significant age-related declines in TP, HG, and ODK, especially after 65 years of age. Factors affecting MP were posterior teeth, the Eichner index, bite force, occluding area, the Korean Mini-Mental State Examination (KMMSE) score, and ODK. Each ODK syllable was associated with different factors, but common factors associated with ODK were MP, HG, and PHQ-9 score. For the syllables /pa/ta/, the Eichner Index, TP, and oral dryness were also associated. For the syllable /ka/ in Gr3, MP, TP, HG, oral dryness, and the KMMSE score were associated. CONCLUSIONS These results could provide practical guidelines for oral rehabilitation in old adults and contribute to improving the understanding of age-related changes in oral function and the multidimensional nature of masticatory dynamics.

The influence of nocturnal use of complete dentures on cardiorespiratory parameters of patients with obstructive sleep apnea: a systematic review and meta-analysis. Clin Oral Investig 2022; 26:4675-4686.

Abstract
OBJECTIVE To assess whether wearing complete dentures during sleep influences the cardiorespiratory parameters of patients with obstructive sleep apnea (OSA). MATERIALS AND METHODS A systematic review was performed based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to determine whether wearing complete dentures during sleep influences the cardiorespiratory parameters of patients with OSA. An electronic search was performed in four databases, PubMed/MEDLINE, Cochrane Library, Web of Science, and SCOPUS, and in the gray literature (TRIALS) until November 2021. This review included clinical trials, randomized clinical trials, and studies in which patients using conventional complete dentures were diagnosed with OSA using polysomnography and the cardiorespiratory parameters were measured using oximetry or polysomnography during sleep. RESULTS In total, 788 references were found in the database, and 12 articles were selected for full reading. Six articles were selected for qualitative and quantitative analyses after applying the inclusion and exclusion criteria and reading the full article. The meta-analysis showed that mean oxygen saturation (SpO2) increased with the use of complete dentures (p = 0.001), but the other parameters showed no significant differences between those wearing and not wearing dentures during sleep. CONCLUSIONS The mean SpO2 reduced in patients wearing complete dentures, but the other cardiorespiratory parameters evaluated were not affected. CLINICAL RELEVANCE This study indicates a possible influence of the use of complete dentures on the mean SpO2 during sleep. The use of complete denture could aid other treatments in improving respiratory and sleep quality.

Abstract
BACKGROUND The impact of a complete denture on obstructive sleep apnea is not well understood. Therefore, this study aimed to evaluate the relationship between nighttime use of complete dentures and obstructive sleep apnea and determine if wearing a complete denture during sleep changes the degree of obstructive sleep apnea. METHODS This systematic review followed the notification items for Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and was recorded in the International Prospective Registry of Systematic Reviews (PROSPERO) under number CRD42020183167. An electronic search in the PubMed/MEDLINE, Scopus, and Cochrane Library databases for articles published until September 2020 was conducted. The search strategy used the terms (complete denture OR denture OR edentulous OR edentulism) AND (quality of sleep OR sleep OR apnea OR obstructive sleep apnea). Only prospective, retrospective, controlled, and randomized clinical studies of patients wearing complete dentures, studies comparing sleep with and without the prosthesis, and studies in which patients were diagnosed with obstructive sleep apnea by polysomnography were included in the review. RESULTS In total, four articles were selected for the qualitative and quantitative analyses. A total of 144 patients, with an average age of 60 years, were studied. The meta-analysis showed that there was no statistical difference in the apnea-hypopnea index between using and not using the prosthesis during sleep. CONCLUSIONS The use of complete dentures during sleep does not influence the degree of obstructive sleep apnea.

Abstract
PURPOSE The aim of this study is to investigate the relationship between tooth loss and signs and symptoms of obstructive sleep apnea (OSA) in a representative sample of the general US population. METHODS Data were from 7305 men and women aged ≥25 years participating in the 2005-2008 National Health and Nutrition Examination Survey. Tooth loss, occlusal contacts, and denture use were determined by dental examination. Four cardinal OSA signs and symptoms were evaluated by questions based on American Academy of Sleep Medicine criteria. Adults with ≥2 signs/symptoms of OSA were classified at high-risk of OSA. Prevalence ratios (PR) and 95 % confidence limits (CL) from log binomial regression models estimated the strength of association between tooth loss and high-risk for OSA, adjusting for demographic characteristics, body mass index, dentures, and sleep duration. RESULTS Prevalence of high-risk for OSA increased 2 % for each additional lost tooth (PR = 1.02, 95 % CL, 1.01, 1.03) among adults aged 25 to 65 years. When tooth loss was modeled as an ordinal variable with 0-4 lost teeth as the referent category, adjusted prevalence of high-risk for OSA was as follows: 25 % greater in those missing 5-8 teeth (PR = 1.25, 95 % CL, 1.07, 1.46); 36 % greater in those missing 9-31 teeth (PR = 1.36, 95 % CL, 1.06, 1.73); and 61 % greater in the edentulous (PR = 1.61, 95 % CL, 1.11, 2.33). CONCLUSION Tooth loss may be an independent risk factor for OSA.

Abstract
PURPOSE Previous work has shown that monolingual French and English speakers use distinct articulatory settings, the underlying articulatory posture of a language. In the present article, the authors report on an experiment in which they investigated articulatory settings in bilingual speakers. The authors first tested the hypothesis that in order to sound native-like, bilinguals must use distinct, language-specific articulatory settings in monolingual mode. The authors then tested the hypothesis that in bilingual mode, a bilingual individual's articulatory setting is identical to the monolingual-mode setting of 1 of his or her languages. METHOD Eight French-English bilinguals each read 90 English and 90 French sentences, and the authors measured their interspeech posture (ISP) using optical tracking of the lips and jaw and ultrasound imaging of the tongue. RESULTS Results show that bilingual speakers who are perceived as native in both languages exhibit distinct, language-specific ISPs, and those who are not perceived as native in one or more languages do not. In bilingual mode, bilinguals use an ISP that is equivalent to the monolingual-mode ISP of their currently most used language. The most balanced bilingual used a French lip ISP but an English tongue-tip ISP. CONCLUSION Results support the claim that bilinguals who sound native in each of their languages have distinct articulatory settings for each language.

Abstract
OBJETIVO: verificar a confiabilidade da informação fornecida por adultos e crianças a respeito do posicionamento habitual de língua. MÉTODOS: foram investigadas 30 crianças e 30 adultos em dois momentos, com diferença mínima de sete e máxima de vinte e um dias. Inicialmente foi realizada a observação do posicionamento habitual de língua. Em seguida, o participante foi questionado a respeito de seu posicionamento habitual. Após a resposta, a língua foi estimulada com uma espátula de madeira, a fim de aumentar a percepção. Posteriormente, questionou-se, novamente, o indivíduo. Em seguida, orientou-se o participante a observar onde sua língua permanece habitualmente na cavidade oral, até o segundo momento da avaliação. Nesta oportunidade, o participante foi questionado a respeito de seu posicionamento habitual de língua. Os dados foram analisados por meio da estatística Kappa. RESULTADOS: não foi possível visualizar o posicionamento habitual de língua em 100% da amostra. Quanto à confiabilidade geral das respostas verificou-se classificação entre discreta e regular. As crianças apresentaram respostas pouco consistentes e bastante diversificadas, já em relação aos adultos, parte apresentou respostas corretas logo no primeiro questionamento e parte somente apresentou respostas confiáveis após estimulação de percepção intra-oral. CONCLUSÕES: a confiabilidade da informação fornecida pelos indivíduos da amostra a respeito de seu posicionamento habitual de língua varia entre discreta e regular, sendo, portanto, baixa, tanto em crianças quanto em adultos. Uma possível estratégia a ser utilizada na prática clínica fonoaudiológica é questionar o paciente quanto ao seu posicionamento lingual após determinado período de observação.

Abstract
Many elderly patients have various health problems and are susceptible to recurrent fever. We examined the influence of oral health on the febrile status of 271 long-term hospitalized elderly patients over 1 year. In dentate patients, those with > or =20 teeth had a significantly higher risk for fever than those with 1-9 teeth; multivariate logistic regression analysis: odds ratio (OR)=5.44, 95% confidence interval (CI)=1.37-21.66. In edentate patients, those with moderate or much tongue plaque had a significantly higher risk for fever than those with no or slight tongue plaque; multivariate analysis: OR=5.14, 95% CI=1.77-14.88. These results suggest that oral health status related to febrile status differs between dentate and edentate patients in the elderly population.

Abstract
Neck extension because of contraction of cervical extensor muscles often brings about a lower-positioned tongue secondary to jaw opening in patients with congenital myopathy (CM). We hypothesized that neck extension in control subjects would reproduce the lower position of the tongue similar to that found in a CM patient. A simple method was formulated to evaluate the tongue position in terms of tongue pressure on the maxillary molar. A pair of pressure sensors was attached to the buccal and lingual surfaces of the upper molar for both the CM patient and four control subjects. Changes in the buccal and tongue pressures were recorded at the neck extension position for the CM patient and during both the natural head position and neck extension for the control subjects. There was a remarkable difference between buccal and tongue pressures in the neck extension position in the CM patient: tongue pressure was not detected at all, indicating there was no contact between tongue and upper molar. The buccal and tongue pressures were approximately equal in the natural head position in the control subjects. However, both buccal and tongue pressures were reduced during neck extension in the control subjects, with a greater decrease in the tongue pressure than the buccal pressure. These findings suggest that neck extension in a control subject reproduces the lower position of the tongue observed in CM patients. We propose that the pressure sensor enables evaluation of the tongue position, but further investigation is required.
