High-need dental deserts in England: a national spatial analysis of NHS access and deprivation.
Article in British dental journal, 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
Aims The aim of this study was to identify high-need dental deserts in England and quantify the population affected and profile the demographics relative to other deserts.Methods Lower Layer Super Output Area (LSOA) December 2021 boundaries were linked to Index of Multiple Deprivation (IMD) 2025 (deciles; mid-2022 population). National Health Service (NHS) dental practices were geocoded using the ONS Postcode Directory (British National Grid). Euclidean distance from each LSOA centroid to the nearest NHS-listed practice was calculated; LSOAs with no provider within 5 km were classified as dental deserts. High-need deserts were deserts in IMD deciles 1-3. Demographic profiling used Census 2021 ethnicity (TS021) and age structure (TS007a).Results Across England, 1,340 LSOAs (population 2,342,985) had no NHS-listed dental provider within 5 km. The high-need deserts comprised 112 LSOAs (189,542 residents). A further 2,153,443 residents in the IMD 4-10 group lived in dental deserts. The high-need desert population was predominantly white (97.9%) and had a similar age structure to other deserts not in the IMD 1-3 group (0-15: 19.4% versus 19.5%; 65+: 27.4% versus 26.9%).Conclusion Geographic exclusion from NHS-listed dental provision affects ~2.3 million residents. Spatial audits linking deprivation and access could support targeted service planning.
