Longitudinal Patterns of Dental Health Care Utilization 18 Months Before and 36 Months After Initiation of Index Medications for Opioid Use Disorder.
Article in Journal of addiction medicine, 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
objectivesIn 2022, the FDA issued a drug safety communication based on case studies that transmucosal buprenorphine, a medication for opioid use disorder (MOUD), may contribute to dental disease. We sought to assess longitudinal dental care utilization patterns among patients with opioid use disorder (OUD) in the 18 months before and 36 months after MOUD initiation.
methodsUsing data from the Veterans Affairs Corporate Data Warehouse (2003-2020), we created a cohort of patients coded for OUD and prescribed MOUD. Outcomes included preventive and therapeutic dental visits and oral infections within 18 months before and up to 36 months after index MOUD. We used unadjusted Poisson models to estimate incidence per 1000 patients by MOUD. We performed analyses with and without interval censoring for edentulism, death, or a 60-day gap in MOUD.
resultsAmong 49,675 eligible patients, 21,551 received methadone, 17,759 transmucosal buprenorphine, 8993 oral naltrexone, and 1372 injectable naltrexone. Median (IQR) days on treatment varied by drug: methadone 95 (52, 257), buprenorphine 309 (102, 968), oral naltrexone 49 (30, 101), injectable naltrexone 28 (28, 85). We observed an immediate increase in dental visits from a baseline range of 135-144 visits/1000/6-month period to 223-686 visits/1000/6-month period after initiating any MOUD. Patterns were similar by MOUD agent and formulation. Results were similar in analyses with and without interval censoring.
conclusionsBoth preventive and therapeutic dental utilization increased immediately following initiation with MOUD. Future observational studies of the effects of MOUD on adverse dental outcomes should account for confounding due to health-seeking behavior.
