Association between Sleep Duration, Dental Caries, and Periodontitis in Korean Adults: The Korea National Health and Nutrition Examination Survey, 2013∼2014

Abstract: We evaluated the association between sleep duration, dental caries, and periodontitis by using representative nationwide data. We examined 8,356 subjects aged ≥19 years who participated in the sixth Korea National Health and Nutrition Examination Survey (2013∼2014). Sleep duration were grouped into ≤5, 6, 7, 8, and ≥9 hours. Presence of dental caries was defined as caries in ≥1 permanent tooth on dental examination. Periodontal status was assessed by using the community periodontal index (CPI), and a CPI code … Show more

“…A CPI score of 0 represents healthy periodontal tissue, 1 means bleeding periodontal tissue, 2 means periodontal tissue with plaques, 3 means periodontal tissue with shallow periodontal pockets (3.5 ≤ pocket depth < 5.5 mm), and 4 means periodontal tissue with deep periodontal pockets (pocket depth ≥ 5.5 mm) . In this study, a score of 3 to 4 was considered to denote periodontal disease …”

“…According to previous studies, sleep disorders affect saliva flow. Although the exact cause has not been identified, it was confirmed that a change in the saliva flow rate leads to an increase in the incidence of dental caries and periodontal disease (Lee and Lee 2017). Dental caries, periodontal disease, and oral malodor are multifactorial diseases, of which saliva factors, such as secretion rate, acidity, and buffering capacity, have a significant influence on the occurrence of the diseases (Brooks et al 1997;Gunepin et al 2018).…”

“…In previous study by Suzeki et al, decreased resting salivary flow was a strong explanatory factor in clinical findings of oral malodor [ 25 ]. In another studies, chronic sleep deficiency caused daytime drowsiness, and subjects who experienced daytime sleepiness reported a decrease in saliva compared with those who did not [ 27 , 28 ].…”
