The nocturnal use of complete dentures and sleep stability in edentulous elders
Available online 8 June 2013
Abstract
Objective
To
evaluate the stability of sleep quality and the impact of nocturnal use
of complete dentures on sleep quality in an elderly edentulous
population over a one-year period.
Materials and methods
Written
informed consent was obtained from 172 edentulous elders who agreed to
enrol in a longitudinal cohort study. A total of 153 participants
completed the follow-up after one year. Perceived quality of sleep and
daytime sleepiness were measured using the Pittsburgh Sleep Quality
Index (PSQI, score 0-21) and the Epworth Sleepiness Scale (ESS, score
0-24) at baseline (T0) and at follow-up (T1). Data
on oral health related quality of life, type of mandibular dentures
(conventional versus implant-retained mandibular overdenture), nocturnal
wear of the dentures and socio-demographic status were obtained by
means of the OHIP-20 questionnaire, a clinical examination form and a
socio-demographic questionnaire.
Results
No
statistically significant differences were detected in the global PSQI
mean scores and EES mean scores from baseline (PSQI 4.77 ± 3.32; EES
5.35 ± 3.72) to the follow-up assessment
(PSQ1
5.04 ± 3.50; EES 5.53 ± 4.34). Edentate elders wearing prostheses at
night had poorer daytime sleepiness scores than those who removed their
prostheses at night (p= 0.003 unadjusted model; p = 0.058 adjusted for age, gender, type of prosthesis and the OHIP-20 total score).
Conclusion
Results
of this study suggest that wearing complete dentures while sleeping has
little effect on sleep quality or daytime sleepiness.
