1 · What the graph read from it

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.

2 · The registry

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

objectiveThis study aimed to evaluate the effectiveness of a 3D printed training kit for the preparation of endodontic access cavities in calcified teeth.

methodsThe root canal system of a micro-CT scanned premolar was digitally processed to create an endodontic training kit containing 10 teeth with ten different progressive degrees of pulp canal calcification. A tooth variant with a medium calcification degree (5/10) was printed in three copies using opaque resin. Additionally, a set of 10 transparent training teeth with red-colored pulp was produced using PolyJet 3D printing technology, which was used to train the access cavity preparation in a controlled manner due to the transparency of the teeth. Undergraduate students (n=27) and dentists (n=10) each prepared a total of 13 (one pre-training, two post-training) access cavities. Substance loss was quantified by CBCT, and user satisfaction was evaluated by questionnaire. Paired t-tests were used to compare the means for substance loss and procedure time for pre- and post-training conditions. Unpaired t-tests were used to compare differences between students and dentists. The level of significance was set at α=0.05.

resultsMean substance loss before and after training decreased for both students (71.4 versus 54.68 mm3; p=0.069) and dentists (67.3 versus 51.1 mm3; p=0.633), but the difference was not statistically significant. The average preparation time decreased with training for students (420 versus 275 seconds; p=0.100) and dentists (336 versus 158 seconds; p=0.054), but not significantly. Root perforation rates also decreased (students: 6/27 versus 4/27; dentists: 1/10 versus 0/10). Participants rated the training model as very realistic and useful, despite the difference in material texture.

conclusionThe proposed 3D printed training kit appears to be a suitable tool for undergraduate dental students, which could expand their opportunities to practice the preparation of endodontic access cavities in calcified teeth. (EEJ-2024-06-091).
