Investigation of root apical closure of first permanent molars with cone-beam computed tomography: A retrospective study.
Article in Journal of dental sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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/purpose: The objective of this study was to assess the root apical closure ages of first permanent molars retrospectively among a group of western Turkish children aged between 5 and 15 years using cone-beam computed tomography (CBCT). Materials and methods: CBCT images of 202 patients were examined. The patients were divided into 7 groups according to age: ≤8 years, 8-8.99 years, 9-9.99 years, 10-10.99 years, 11-11.99 years, 12-12.99 years, and ≥13 years. Teeth with at least one open apex were considered as 'teeth with open apex' and teeth with all closed apices were considered as 'teeth with closed apex'. The data was evaluated by Pearson Chi-square test and Fisher's exact test. Results: Apical closure rate of the maxillary first molars was 4.1%, 32.2%, 55.4%, 76.2%, and 90.6% at 8-8.99 years, 9-9.99 years, 10-10.99 years, 11-11.99 years, and 12-12.99 years, respectively. Apical closure rate of the mandibular first molars was 4.4%, 41.2%, 70.7%, 80.0%, and 92.2% at 8-8.99 years, 9-9.99 years, 10-10.99 years, 11-11.99 years, and 12-12.99 years, respectively. At 12-12.99 years, females had a significantly higher rate of closed root apices of mandibular first molars than males ( Conclusion: CBCT is a useful tool for the evaluation of root development. The results of present study can provide valuable aids for clinicians during root canal treatment of permanent first molars.
