Official title

IntelliPrep: An AI-Driven Digital Self-Assessment Framework for Preclinical Tooth Preparation-A Randomized Controlled Trial

Overview

This study aims to compare traditional faculty-based assessment with two AI-assisted digital self-assessment software programs for evaluating tooth preparations for metal-ceramic crowns for undergraduate dental preclinical students at College of Dentistry El Alamein, AAST in terms of: (1) Accuracy of preparation outcomes, (2) Student learning outcomes over a training period.

Interventions

  • Other Non-metrology-grade digital group (NMG)
    Students in NMG used a license-free 3D comparison workflow (Medit Link/Compare, Compare tool; Medit Compare v3.4.9; Medit) to superimpose the prepared-tooth scan (TT-STL) onto the unprepared reference scan (RTS-STL).
  • Other metrology-grade digital group (MG)
    Students in MG used metrology-grade 3D inspection software (Geomagic Control X v2018.1.1; 3D Systems)to superimpose TT-STL onto RTS-STL. Initial Alignment was performed followed by Best Fit Alignment (iterative closest point registration).
  • Other Traditional group (TG)
    Students in TG assessed reduction with a silicone putty index and a periodontal probe across the previously predefined regions. Feedback was provided by experienced instructors (≥5 years of clinical teaching experience) using the same regional assessment approach.

Primary outcome measures

  • Change in preparation scores [Time frame: Up to 5 weeks]
  • RMS deviation from the ideal preparation [Time frame: Up to 5 weeks]

Eligibility criteria

Inclusion criteria

  • Third-year preclinical dental student
  • Completion of the fixed prosthodontics tooth-preparation course.
  • No prior formal training or use of digital 3D tooth-preparation assessment software.

Exclusion criteria

  • previous repetition of the course
  • Substantial prior experience with digital metrology/3D inspection software
  • Inability to attend all scheduled training and examination sessions.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
