Patient Specific Classification of Dental Root Canal and Crown Shape

Area of Science:

• Dentistry
• Medical Imaging
• Machine Learning

Background:

• Analyzing dental morphology requires integrating data from different imaging modalities.
• Precision in dentistry relies on dental crown surface characteristics and root shape/position.
• Accurate root analysis is crucial for endodontics, orthodontics, and restorative/implant dentistry.

Purpose of the Study:

• To propose machine learning (ML) methods for integrating dental crown and root imaging modalities.
• To develop a patient-specific workflow for analyzing dental root canal and crown morphology.
• To overcome challenges in precisely analyzing crowns and roots using disparate imaging techniques.

Main Methods:

• Utilizing image processing and ML to combine data from intraoral scanners (crowns) and cone beam computed tomography (CBCT) (roots).
• Developing a patient-specific classification workflow for dental root canal and crown shape analysis.
• Integrating 3D volumetric images of jaws and teeth root canals with crown surfaces.

Main Results:

• Demonstration of a novel approach for joint analysis of tooth crowns and roots.
• Establishment of a widely applicable workflow for patient-specific dental morphology analysis.
• Improved potential for precise analysis by combining imaging modalities.

Conclusions:

• Machine learning offers a powerful tool for integrating diverse dental imaging data.
• The proposed workflow enables comprehensive and patient-specific analysis of tooth morphology.
• This approach has broad applicability in advancing dental research and clinical practice.
