“…Their findings showed higher chances of short sleep duration among individuals with less than 20 teeth. (Al-Zahrani et al, 2020;Carra et al, 2017;Koyama et al, 2018) Like the present study, Azuma et al (Azuma et al, 2019) observed that adults reporting poor chewing ability had a higher chance of poor sleep quality.…”

“…Previous studies investigating this subject were conducted among adults and mostly evaluated sleep quality, as measured by the self‐reported number of sleep hours, and used the number of teeth as the oral health measure (Al‐Zahrani et al., 2020; Carra et al., 2017; Koyama et al., 2018). Their findings showed higher chances of short sleep duration among individuals with less than 20 teeth (Al‐Zahrani et al., 2020; Carra et al., 2017; Koyama et al., 2018).

“…More recently, the consistent association between oral health and general health conditions (Kazemi et al., 2011; Morita et al., 2012; Tsakos et al., 2010; Yamamoto et al., 2017) (e.g., diabetes, hypertension, mental health, poor diet), which are well‐known to be related to sleep disorders and sleep quality (Alvaro et al., 2013; Liu et al., 2013; Stickley et al., 2019; St‐Onge et al., 2016), raised the attention to the possible effect of poor oral health on sleep (Al‐Jewair et al., 2015; Al‐Zahrani et al., 2020; Beydoun et al., 2020; Carra et al., 2017; Sanders et al., 2016). These studies investigated the impact of tooth loss and periodontal disease on obstructive sleep apnea (OSA) and sleep quality (Al‐Jewair et al., 2015, p.; Al‐Zahrani et al., 2020, p.; Azuma et al., 2019; Carra et al., 2017; Koyama et al., 2018; Sanders et al., 2016). In edentulous individuals, OSA could be caused by the loss of the occlusion vertical dimension resulting in a forward position of the mandible leading to tongue root retraction which might compromise the patency of the upper airway (Sanders et al., 2016).…”

Poor sleep quality and oral health among older Brazilian adults

Objectives This study evaluates the association between normative and subjective oral health measures and poor self‐reported sleep quality among community‐dwelling older adults in Brazil. Methods This was a cross‐sectional study with data from the Brazilian Longitudinal Study of Aging. The dependent variable was the poor sleep quality. Independent variables of interest included number of teeth and self‐reported impact of oral health on eating/chewing and on maintaining emotional stability. Results Poor sleep quality was reported by 17.8 (95% CI 16.6; 19.2) of the participants, 29% of the participants were edentulous, and 30% had 20 or more teeth. Impacts of oral health on eating and maintaining emotional stability was found among 33.3% and 20% of the older adults, respectively. After adjusting for all oral health measures and covariates, the magnitude of the associations between the number of teeth and sleep quality was attenuated. Sleep quality was related to oral health impacts on eating (OR 1.19 [95% CI 1.00; 1.41]) and on emotional stability (OR 1.51 [95% CI 1.21; 1.87]). Conclusions This study found an association between oral health and sleep quality emphasizing the importance of oral health to general health.

“…Long sleep duration of 9 hours or more has been shown, in several epidemiological studies to be related to an increased morbidity and mortality [32][33][34]. In addition, it was shown to be associated with a higher periodontitis prevalence among women and fewer remaining teeth among elderly [35,36]. As long sleep duration might have harmful effect, combining adequate and long sleeper into a single category would probably dilute any significant results, which would explain the inconsistency in the results between the present study and Weiner's results.…”

This study was undertaken to investigate the potential association between sleep duration and periodontitis. The study population consisted of 10,291 individuals who participated in the United States National Health and Nutrition Examination Survey (NHANES) from the 2009-2014 cycles. Sleep duration was categorized into sleep deficient (< 7 hours), sleep adequate (7-8 hours), and sleep excessive (> 8 hours). We used the Center for Disease Control and Prevention (CDC) and the American Academy of Periodontology (AAP) periodontitis case definition. Descriptive statistics and logistic regression models were used for data analyses. The prevalence of periodontitis was 36% higher in individuals who reported sleep deficiency when compared to the sleep adequate group (odds Ratio (OR) = 1.36, 95% confidence interval (CI): 1.23-1.50). Those who reported excessive sleep had 41% higher odds of periodontitis (OR: 1.40, 95% CI: 1.16-1.71). After adjusting for confounding factors, sleep deficient individuals were 19% more likely to have periodontitis when compared to sleep adequate individuals (OR: 1.19, 95% CI: 1.06-1.38). Among sleep excessive individuals, the association was non-significant (OR: 1.16, 95% CI: 0.94-1.43). Sleep deficiency was associated with a higher prevalence of periodontitis in this study population. The association however needs to be confirmed in longitudinal studies.

“…Some studies are available regarding the relationship between oral health and sleep. A cohort study found that older adults with <10 teeth are at higher risk for short and long sleep durations, compared with individuals with ≥20 teeth [9]. e findings of a cross-sectional study have suggested a positive association between sleep problems and gingival inflammation [10].…”

An association between physical illness and sleep has been suggested. Disordered chewing might be a physical factor that is associated with sleep issues. This cross-sectional study aimed to determine whether chewing problems are associated with sleep in Japanese adults. Sleep and chewing issues were evaluated in 6,025 community residents using a self-reported questionnaire. The prevalence of poor sleep quality and sleeping for <6 h/day (short duration) were 15.6% and 29.4%, respectively. Multivariate logistic regression analyses showed that prevalence of poor sleep quality was significantly associated with self-reported medical history (odds ratio (OR), 1.30; p<0.001), self-reported symptoms (OR, 4.59; p<0.001), chewing problems (OR, 1.65; p<0.001), and poor glycemic control (OR, 1.43; p=0.035). The prevalence of short sleep duration was also significantly associated with female sex (OR, 1.23; p=0.001), self-reported symptoms (OR, 1.60; p<0.001), chewing problems (OR, 1.30; p=0.001), and being overweight (OR, 1.41; p<0.001). In conclusion, chewing problems were associated with poor sleep quality and short sleep duration among Japanese adults.
