The association between tooth loss and serum cholesterol levels in adults: a scoping review.
Article in BMC oral health, 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
objectiveThis scoping review systematically mapped the evidence on the association between tooth loss and serum cholesterol levels in adults, addressing a significant gap in understanding the direct link beyond broader systemic conditions such as cardiovascular disease.
methodsIn accordance with the PRISMA-ScR guidelines, a comprehensive search of four electronic databases (PubMed, MEDLINE, EMBASE, and Cochrane Library) was conducted from July 1968 to September 2025. Studies involving adults (≥ 18 years) that quantified tooth loss and reported serum lipid profiles specifically high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, total cholesterol, and/or triglycerides levels - were included.
resultsAmong the 23 studies synthesized, a majority demonstrated a significant association between greater tooth loss and adverse lipid profiles, characterized by lower high-density lipoprotein cholesterol levels, higher low-density lipoprotein cholesterol levels, and elevated triglyceride levels. A dose-response relationship was evident, with more extensive tooth loss correlated with progressively worsening cholesterol levels. Analysis of edentulous populations suggested that the primary mechanism in this population may be nutritional maladaptation from impaired masticatory function rather than systemic inflammation. Some evidence indicates a bidirectional relationship, where dyslipidemia may also be a risk factor for tooth loss. Notably, prosthetic rehabilitation for partial tooth loss was associated with improved cholesterol levels, an effect not consistently observed with complete dentures.
conclusionThis scoping review suggests an association between tooth loss and dyslipidemia, which may be mediated through dietary changes due to reduced masticatory function and systemic inflammatory pathways. However, as a scoping review that included studies of heterogeneous designs and did not perform a formal risk of bias assessment, these results are indicative of an association and cannot establish causality. Despite these limitations, the gathered evidence underscores the importance of considering oral health when developing strategies to maintain metabolic health.
