The interplay of sleep disorders and orofacial pain: A systematic review.
Review in Journal of clinical and experimental dentistry, 2025. 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
Background: Chronic orofacial pain (OFP) and sleep disorders are highly prevalent conditions that significantly impact quality of life. Increasing evidence suggests a bidirectional relationship between these disorders, whereby sleep disturbances may exacerbate OFP and vice versa. This systematic review synthesizes current evidence on the influence of sleep disorders on chronic OFP and explores additional factors that may contribute to this interaction. Material and Methods: A systematic review was conducted following PRISMA 2020 guidelines and registered the study with PROSPERO (CRD4202525111587). PubMed, Scopus, and Web of Science were searched for relevant literature published between 2004 and March 2024. Randomized controlled trials, cross-sectional studies, case-control studies, and cohort studies examining the association between sleep disorders and OFP were included. Ten studies met the eligibility criteria. Results: A consistent association was identified between chronic OFP and sleep disorders, particularly insomnia and obstructive sleep apnea (OSA), with stronger correlations observed in women. Limited evidence also suggests that OFP severity may increase with age and that greater sleep disturbance correlates with more intense pain. Limitations: The paucity of high-quality studies specifically addressing the relationship between sleep disorders and chronic orofacial pain was a notable issue. Additionally, there was significant methodological heterogeneity among the included studies, especially regarding study design, diagnostic criteria, and assessment tools. The decision to include only studies focused on orofacial pain and to exclude other categories of pain-related diseases, such as temporomandibular joint disorders (TMD), introduced an additional challenge and resulted in a reduction of the number of selected studies. Conclusions: There is a strong connection between chronic orofacial pain (OFP) and sleep disorders, particularly insomnia and obstructive sleep apnea (OSA). Addressing sleep-related issues could be an effective complementary approach in managing OFP, especially in female patients. More research is necessary to clarify the underlying mechanisms and to develop targeted, interdisciplinary interventions.
