Tooth loss as a factor associated with deterioration of quality and increase in sleep duration: analysis of the 2016-2017 Chilean National Health Survey.
Article in BMC oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTooth loss has been associated with various systemic diseases, but its relationship with sleep disturbances remains understudied. This study aimed to evaluate the association between tooth loss and sleep quantity and quality parameters in Chilean adults.
methodsThis cross-sectional analysis utilised data from the 2016-2017 Chilean National Health Survey (n = 5,009). Tooth loss was categorized as functional dentition (≥ 20 teeth), moderate tooth loss (10-19 teeth), severe tooth loss (1-9 teeth), and edentulism (0 teeth). Sleep quantity was classified as insufficient (< 7 h), adequate (7-8 h), or excessive (> 8 h). Sleep quality was assessed through four questions addressing snoring frequency, breathing pauses, daytime sleepiness, and morning tiredness. Multinomial logistic regression models estimated odds ratios (OR) and 95% confidence intervals (CI), adjusted for sociodemographic, lifestyle, and health-related covariates.
resultsThe association between edentulism and excessive sleep duration was significant in unadjusted models (OR 1.94, 95% CI 1.48-2.56) but attenuated after full adjustment (OR 1.35, 95% CI 0.94-1.94). Edentulous individuals showed higher odds of snoring (OR 1.69, 95% CI 1.29-2.20) and daytime sleepiness (OR 1.58, 95% CI 1.15-2.17) compared to those with functional dentition. Also, severe tooth loss was associated with increased snoring (OR 1.39, 95% CI 1.10-1.75) and daytime difficulty staying awake (OR 1.28, 95% CI 1.02-1.61).
conclusionsThe findings reveal that individuals with severe tooth loss and edentulism are more likely to experience excessive sleep, snoring, and daytime sleepiness, while having a lower likelihood of deficient sleep.
