1 · What the graph read from it

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.

2 · The registry

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

backgroundDental anomalies significantly impact oral structures, particularly impacted maxillary central incisors. These anomalies can complicate interactions with nearby anatomical features like the incisive canal and nasal cavity. Accordingly, this study aimed to three-dimensionally and comprehensively assess the effects of dilacerated impacted maxillary central incisors on the characteristics of incisive canal and nasal cavity. MATERIALS AND

methodsA seventeen cone-beam computed tomography images with an average age of 8.98 ± 0.925 years were classified into a control group and a dilacerated impacted maxillary central incisor group (DIMCI group), each containing 35 patients. A linear, angular, and volume measurements of the incisive canal and nasal cavity were measured using Mimics 21 and Anatomage Invivo Dental 6.0 software. The incisive canal measurements were performed at three levels: H1, the lowest point of the incisive canal buccal wall; H2, midlevel; H3, root apex level.

resultsThe incisive canal volume was significantly lower in the DIMCI group compared to the control group, measuring 109.39 ± 12.28 versus 93.17 ± 12.72 mm³, respectively. Furthermore, the incisive canal widths at the palatal opening and levels H2 and H3 were significantly reduced in the DIMCI group compared to the control group (P < 0.05). Additionally, the contralateral central incisor's angulation was considerably greater (113.18 ± 2.77 vs. 109.09 ± 3.74°), and the anterior nasal floor was significantly narrower (12.27 ± 1.60 vs. 13.61 ± 1.57 mm) in the DIMCI group than in the control group.

conclusionsThe impaction of the maxillary central incisor is related to an increased buccal inclination of the contralateral central incisor and decreased anterior nasal floor width in pediatric patients, indicating a potential need for maxillary expansion. Moreover, a precise evaluation of the incisive canal is necessary for safe management during surgical exposure and orthodontic treatment.
