Summary
This study introduces new dental imaging software that automatically detects root canal orifices in teeth using real-time video analysis. The software achieved a high 97.01% detection sensitivity in tests, enhancing endodontic treatment support.
Area of Science:
- Dentistry
- Medical Imaging
- Computer Vision
Background:
- Real-time image analysis offers advanced treatment support in dentistry.
- Automated detection of root canal orifices is crucial for precise endodontic procedures.
Purpose of the Study:
- To develop and evaluate imaging software for automatic detection of root canal orifices in digital video microscopy sequences.
- To assess the performance and speed of the developed software in identifying root canal openings.
Main Methods:
- Development of specialized imaging software capable of interfacing with digital video microscopes (Motic DM 143).
- Implementation of a Minimum-Distance Classification algorithm for color-based pattern recognition of root canal orifices.
- Testing the software on video sequences from 78 trepanated teeth using a Pentium 4 computer (2 GHz).
Main Results:
- The software demonstrated high accuracy, achieving a mean detection sensitivity of 97.01% across 78 teeth.
- The image processing speed ranged from 30 to 64 ms per image at a resolution of 352 x 288 pixels.
- The developed system successfully detected almost all root canal orifices in the tested samples.
Conclusions:
- The developed real-time image analysis software significantly enhances dental treatment support by accurately detecting root canal orifices.
- The Minimum-Distance Classification algorithm provides a fast and effective method for automated orifice recognition in endodontics.
- This technology holds potential for improving the precision and efficiency of endodontic procedures.
