A pilot study on the application of a digital dental teaching evaluation system in Class II cavity preparation teaching.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo explore the feasibility of applying the digital evaluation system in the homogeneous training and qualification evaluation of teaching faculty in the preclinical simulation teaching of G.V. Black Class II cavity tooth preparation in operative dentistry.
methodsEighteen clinicians who graduated with Ph.D. and were about to participate in the operative dentistry preclinical teaching at the Hospital of Stomatology, Sun Yat-sen University, were selected to practice the G.V. Black Class II cavity tooth preparation of the left mandibular first molar by using the Aizhixing Digital Dental Virtual Teaching Evaluation System DHC210. Through continuous practice and assessment, we evaluated whether there were changes in their examination scores and operation time after practicing with multiple teeth. Meanwhile, we evaluated the condition of Class II cavity tooth preparation before and after practices using Fair Grader 2000, a Dental Digital Teaching Practice Evaluation System, and combined it with questionnaires to examine the teaching effectiveness of this training.
resultsAs the number of exercises increased, there was a tendency for the result scores of the four tests of Aizhixing to increase (P > 0.05), and the operating time was progressively less (P < 0.05). The results of Fair Grader 2000 showed that dental clinicians who had completed their standardized residency training had higher and more stable scores than those who were ongoing (P < 0.05). The questionnaire survey results showed that it was necessary to apply Aizhixing to Class II cavity tooth preparation teaching activities, which can effectively improve students' theoretical knowledge and the level of cavity preparation skills.
conclusionThe application of the digital real-time evaluation system of Aizhixing and the digital evaluation system help to improve the efficiency and objective assessment of Class II cavity tooth preparation, which provides a certain reference basis for achieving high-quality and homogeneous teaching and reform of oral endodontics.
