3D-printed tooth for caries excavation.
Article in BMC medical education, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
backgroundTo date, no suitable model tooth has been available for all standard restorative and prosthodontic procedures. To fill this gap, a realistic multilayer tooth with enamel, dentin, integrated caries, pulp, and electrometric and X-ray imaging abilities was developed. The aim of this study was to test the printed tooth while focusing on caries excavation and pulp capping.
methodsBased on micro-CT data, a tooth was designed and produced via 3D printing. A total of 396 teeth were tested and evaluated by 66 fourth- and fifth-year students experienced in caries excavation at standard typodonts, extracted teeth and patients. They excavated the caries and capped the pulp on six teeth and rated them in a questionnaire.
resultsCompared with natural teeth, the printed teeth were generally rated positively and significantly better in all criteria than typodonts used previously (p < .001). They were rated as a suitable training option (Ø 2.3 ± 0.9) with fair examination conditions (Ø 2.1 ± 0.8) and easy to use (Ø 2.0 ± 0.8). Subjective learning success was also significantly greater (Ø 2.3 ± 0.9) than that of standard typodonts (Ø 3.2 ± 1.1) (p < .001). In general, the students desired more exercises with 3D-printed teeth for their studies (Ø 1.8 ± 0.8).
conclusionsMultilayered 3D-printed teeth were successfully tested and can improve and extend the teaching methods used for caries excavation and pulp capping. Its other abilities will be tested in subsequent studies. YEAR OF THE STUDY: 2023.
