Improving children's use of care in Oregon: The role of a novel dental accountable care organization.
Observational study in Journal of the American Dental Association (1939), 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
backgroundDespite lowering financial barriers to oral health care through the Patient Protection and Affordable Care Act, income-related access-to-care disparities remain, especially in Oregon. The authors examined the role of a novel dental care organization, the Willamette Dental Group (WDG), in addressing the nonfinancial barriers to oral health care that keep access-to-care disparities in place.
methodsThis longitudinal observational study used dental claims and enrollment data from the Oregon Health Plan from 2014 through 2021. The primary outcome measures were any dental visit and an examination visit. Enrollees in the Oregon Health Plan aged 0 through 18 years who were members of WDG's Medicaid population were compared with those in the non-WDG Medicaid population. A propensity score subclassification matching method using child-, family-, and community-level variables was used to approximate a randomized study and reduce bias.
resultsThe percentage of children who had any dental visit or an examination visit was significantly (P < .001) higher among the WDG members than non-WDG members. Compared with non-WDG programs, a child in the WDG program had a 40% higher chance of having any visit and a 48% higher chance of having an examination visit.
conclusionsChildren enrolled with WDG under the Oregon Health Plan experienced substantially higher oral health care use than children in non-WDG programs. Future studies should focus on the correlation of improved use with oral health outcomes at WDG. PRACTICAL IMPLICATIONS: The innovative practice policies of WDG may lead the way for other large-scale dental delivery programs hoping to improve use for children enrolled in Medicaid. Future studies can benefit from the observational methodology used in this study.
