Analysis of cervical bone mineral density in children and adolescents using cone beam computed tomography combined with liquid phantoms.

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
To describe cervical bone mineral density (BMD) in children and adolescents using Cone-beam Computed Tomography (CBCT) combined with K2HPO4 liquid phantoms. Children and adolescents aged 7-19 years who underwent CBCT for orthodontic treatment in our imaging department between January 2023 and June 2023 were selected. The CT values of the second (C2) and third (C3) cervical vertebrae were measured using the software supplied with the CBCT. K2HPO4 liquid phantoms were prepared according to standard protocols and scanned monthly. Regression equations were established between BMD values and CT values. The BMD values of C2 and C3 were then calculated and subsequently analyzed. A total of 455 children and adolescents participated in the study. The BMD values for females were found to be significantly higher than those for males across all age groups (P < 0.05). When comparing the BMD values between C2 and C3, a statistically significant difference was observed (P < 0.05). Furthermore, there were notable variations in the BMD values of C3 among females across different age groups (P < 0.05). However, no significant differences were detected in the BMD values of C2 overall or in the BMD values of C3 among males across no significant differences were detected across different age groups (P > 0.05). The results of this study provide reference values for BMD of C2 and C3 using CBCT combined with liquid phantoms. These reference values, obtained from healthy individuals, enable the assessment of BMD for systemic bone metabolism, orthodontics, implants, and tooth extraction, providing significant economic and social benefits.
