Accuracy of Different Dental Age Estimation Methods Using Cone Beam Computed Tomography: A Comparative Study.
Article in International journal of clinical pediatric dentistry, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Age assessment is useful in various fields of dentistry due to its ability to influence the planning of dental treatments. Dental age estimation methods are specifically based on age-related variables observed in two-dimensional (2D) radiographs in the dentition in terms of the time of emergence and are considered reliable in determining the chronological age; however, the inevitable problems of orientation errors found in 2D can be eliminated using cone beam computed tomography (CBCT). Objective: This study aimed to compare the accuracy of different radiological dental age estimation methods using CBCT in relation to the chronological age of children. Materials and methods: A total of 100 CBCT images of patients in the age-group of 8-15 years requiring orthodontic treatment were obtained from December 2019 to August 2022. The exact chronological age was determined through valid proof, that is, aadhar card or birth certificate. The dental age of the children was assessed using all four methods-Nolla's method (NM), Demirjian method (DM), Schour and Massler (S&M), and Cameriere method (CM). Results: The results found that NM underestimated the mean age by 0.24 years, while DM overestimated the mean age by 0.82 years. Both showed statistically significant differences based on the standard deviation (SD) ( Conclusion: Among the four tested radiographic methods, the best accuracy was found with NM, which tended to underestimate but was closest to the chronological age. CBCT provided better age estimation values without image distortion. How to cite this article: Tyagi A, Srivastava N, Rana V,
