Postoperative pain outcomes following minor oral surgery in opioid tolerant patients: a retrospective cohort study.
Article in Clinical oral investigations, 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
backgroundEvidence guiding postoperative pain management in patients taking prescription or illicit opioids undergoing minor oral surgery is limited. It remains unclear whether standard analgesic protocols for opioid naïve patients provide adequate pain relief in opioid tolerant individuals. This study evaluated whether standard postoperative analgesia achieves adequate pain control in opioid tolerant patients undergoing minor oral surgery with expected mild to moderate pain.
methodsA single centre retrospective study was conducted of patients undergoing minor oral surgical procedures at a public oral surgery service between May 2020 and May 2024. Patients were classified as opioid tolerant if prescribed opioids for longer than one month, receiving methadone therapy, reporting current illicit opioid use, or having a documented history of opioid use disorder. Opioid naïve patients served as controls. Standard postoperative analgesia consisted of paracetamol and non-steroidal anti-inflammatory drugs unless contraindicated. The primary outcome was return with postoperative pain requiring additional opioid analgesia.
resultsA total of 1,263 patient records met inclusion criteria, including 184 opioid tolerant and 1,079 opioid naïve patients. Opioid tolerant patients were significantly more likely to return with postoperative pain requiring additional opioid analgesia compared with opioid naïve patients (28.8% vs. 2.2%; adjusted OR 24.59, 95% CI: 13.26-45.62; p < 0.001). This association remained consistent across demographic subgroups and extraction types.
conclusionsCurrent post operative analgesic pathways may not fully address the analgesic requirements of some opioid exposed patients. This study demonstrates that opioid tolerance is associated with an increased risk of return presentation requiring additional opioid analgesia. CLINICAL RELEVANCE: Opioid tolerance is associated with an increased risk of inadequate postoperative pain control, highlighting the need for tailored analgesia beyond standard regimens.
