Current prevalence and risk factors of apical periodontitis in healthy Saudi adults attending dental school at Najran University: a cross-sectional study using cone beam computed tomography.

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
purposeThis study assessed the prevalence of apical periodontitis (AP) and associated risk factors in healthy Saudi adults attending dental school at Najran university during the period from 2021-2024.
methodsCBCT scans from 420 healthy subjects (6,440 teeth) were reviewed. Data on AP prevalence, both overall and on untreated versus treated teeth, were collected. Scans were retrieved from the School of Dentistry at Najran university, spanning January 2021 to July 2024. Chi-square and multivariable logistic regression analyses were performed to investigate associations with risk factors such as gender, tooth type, root canal treatment adequacy, final restoration status, dental caries, and periodontal disease.
resultsAP was diagnosed in 78.6% of subjects, with a per-tooth prevalence of 12.9%. AP was highly observed in root-canal treated teeth (42.9%) than in untreated teeth (7%). The highest odds of AP were associated with dental caries (OR = 239.8, 95% CI = 151.02-380.72) and endodontic mishaps (OR = 87.03, 95% CI = 38.14-198.64).
conclusionThis study found a high prevalence of AP among healthy Saudi adults attending dental school at Najran university from 2021 to 2024. Significant risk factors included dental caries, periodontal disease, molar teeth, inadequate endodontic treatment, and the absence of full-coverage crowns, while female gender was correlated to greater occurrence of AP. The strong association with dental caries and inadequate root canal treatment highlights the need for early intervention and preventive strategies to reduce the burden of AP.
