Morphometric Analysis of the Incisive (Nasopalatine) Canal and Foramen: Clinical Implications for Anterior Maxillary Surgery.

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
BACKGROUND AND
aimThe incisive (nasopalatine) canal is an important anatomical structure of the anterior maxilla. It holds significance for surgeries and implant placement in the central incisor region. The size, shape, and relation with surrounding bones may vary by age, gender, and ethnicity. Standard radiographs used in dentistry often miss these variations, while cone beam computed tomography (CBCT) allows a precise evaluation in sagittal and axial views. This study aimed to analyze anatomical variations of the incisive canal and surrounding structures, such as canal length, shape, diameter, and bone thickness in the Pakistani subpopulation using CBCT, and compare them across age and gender.
methodsA retrospective cross-sectional study was conducted on 121 high-resolution CBCT scans taken from the Oral Radiology Department, the University of Lahore, from 2021 to 2023. Measurements were done in Planmeca Romexis software (Helsinki, Finland: Planmeca Oy), and statistical analysis was performed using SPSS version 25 (Armonk, NY: IBM Corp.) using t-tests, ANOVA, and nonparametric tests where appropriate.
resultsThe mean age was 34.61±15.38 years. Males had significantly longer incisive canals, thicker palatal bone, and longer incisor roots (p<0.05). Posterior bone width and the distance from incisive foramen to alveolar crest were also greater in males, the latter being marginally significant. Anterior bone width decreased considerably in older age groups, especially above 60 years (p=0.010), while incisor root width showed no gender difference. Hourglass was the most common canal shape (43%), and round foramen shape was slightly more common than oval. No significant differences in shape were seen by age groups and gender.
conclusionThis study shows key anatomical differences in the Pakistani subpopulation. Gender and age affected many linear measurements, while canal and foramen shapes were fairly consistent. The hourglass configuration was the predominant shape of the incisive canal, and the round foramen appeared slightly more frequently than the oval type. These research findings will be useful for implant planning and surgical procedures involving the anterior maxilla.
