Lingual plate thickness influences cortical bone injury during lower third molar extraction: A cone beam computed tomography 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
purposeTo determine which factors influence lingual plate injury during the extraction of mandibular third molars, using cone beam computed tomography (CBCT) analysis, considering tooth position and lingual plate morphology.
methodsThis retrospective study included CBCT images of 35 mandibular third molars taken preoperatively and seven days post-extraction. The images were obtained from a previous prospective clinical trial investigating bone healing. In the preoperative images, six parameters were evaluated: lingual plate thickness, impaction depth, mesiodistal and buccolingual angulation, lingual plate morphology, and the topographic relationship between the root apex and the lingual plate. In the postoperative images, the lingual plate was classified as either intact or fractured. Statistical analysis was performed using logistic regression to assess the influence of the different variables on lingual plate damage.
resultsCBCT images of 35 mandibular third molars were analyzed. Logistic regression analysis revealed that lingual plate thickness at the level of the cementoenamel junction significantly influenced the likelihood of plate fracture during extraction (95% CI: -1.19 to -0.20; p =.007).
conclusionUnderstanding lingual plate thickness variations can aid in surgical planning and reduce intraoperative complications in lower third molars extraction. CBCT may be particularly useful in cases involving complex impactions. CLINICAL TRIAL NUMBER: The clinical trial from which the CBCT images were obtained was registered in the Brazilian Registry of Clinical Trials (REBEC) under number U1111-1263-9675.
