Prevalence and Risk Factors of Post-Extraction Complications in a Western Australian Tertiary Dental Hospital: A Retrospective Cross-Sectional Study.

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
objectivesDental extractions are routine procedures, yet they carry a risk of post-operative complications that can negatively affect patients' quality of life. This study aimed to identify patient-, tooth- and clinician-related risk factors associated with post-extraction complications at Western Australia's only tertiary dental hospital, to inform clinical decision-making and improve outcomes by identifying high-risk groups.
methodsA retrospective audit of patient records was conducted using data from individuals who underwent dental extractions during the audit period. Extracted variables included demographic details, medical history (e.g., smoking status, diabetes, hypertension), extraction characteristics (e.g., simple vs. surgical, tooth location) and clinician factors (e.g., level of training, anaesthesia type). Post-operative complications were identified through clinical follow-up notes. Descriptive and inferential statistical analyses were used to determine significant associations.
resultsThe overall post-extraction complication rate was 11.0%. The most common complications were persistent post-operative pain (4.1%) and alveolar osteitis (3.4%). Statistically significant patient-related risk factors included smoking, uncontrolled diabetes and hypertension. Surgical extractions and mandibular tooth removals were associated with higher complication risks. Extractions performed by students and those conducted under general anaesthesia were also linked to increased complications.
conclusionsApproximately 1 in 10 patients experienced post-operative complications. Identifying modifiable risk factors and minimising surgical complexity may reduce adverse outcomes. Operator experience and anaesthesia choice should be considered during preoperative planning.
