Relationship between bone mineral density and oral health: a cross sectional observational study.
Observational study in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeBone mineral density (BMD) is related to oral health. This study investigated how changes in BMD influence tooth loss risk and dental caries prevalence.
methodsThis cross-sectional observational study included 224 people (199 males and 25 females). The BMD scores of the participants' lumbar spine, femoral neck, and total hip were categorized as normal, osteopenia, or osteoporosis. Oral health was assessed using the Decayed, Missing, Filled Teeth (DMFT) index and Oral Hygiene Index-Simplified (OHI-S) scores. Based on the number of surviving teeth, the participants were categorized into low (< 20) and high (≥ 20) groups. Differences between groups were assessed using independent sample T tests and one-way analysis of variance.
resultsThe normal, osteopenia, and osteoporosis groups comprised 72, 87, and 65 participants, respectively. The OHI-S scores showed no notable variations across the groups. The DMFT index scores were highest (18.69) in the osteoporosis group and lowest (14.08) in the normal group (p < 0.001). Although the number of remaining teeth was lower in the osteoporosis and osteopenia groups compared to the normal group (p < 0.001), that in the osteopenia group approximated the normal group, but was substantially higher than in the osteoporosis group. The group with the lowest number of remaining teeth had lower total hip T-scores, despite significantly higher DMFT indexes (p < 0.001).
conclusionsTooth loss and dental decay rates were significantly high in patients with osteoporosis. Although bone resorption during osteopenia is not excessive, it constitutes a crucial risk factor for dental health. Therefore, attention must be paid to bone resorption treatment in patients with osteopenia.
