Validation of a computer-assisted system on classifying lower third molars.

Area of Science:

• Dental Diagnostics
• Radiographic Analysis
• Software Reliability

Background:

• Accurate classification of lower third molars is crucial for dental treatment planning.
• Traditional methods rely on direct interpretation of orthopantomographs, which can be subject to variability.
• The Radio Memory® software offers a digital approach to this classification.

Purpose of the Study:

• To evaluate the reliability of the Radio Memory® software for classifying lower third molars.
• To assess both intra- and interexaminer agreement when using the software.
• To compare the software's performance against conventional methods.

Main Methods:

• An observational, descriptive study involving 280 lower third molars.
• Analysis of orthopantomographs using Radio Memory® software by two independent examiners.
• Repetition of the examination after 30 days to assess intra-examiner reliability.
• Statistical analysis of intra- and interexaminer agreement using SPSS v 12.0.

Main Results:

• High intra- and interexaminer agreement was observed for both Pell & Gregory and Winter classifications.
• A statistically significant correlation (p<0.01) was found between variables.
• The software demonstrated 99% significant correlation in all cases analyzed.

Conclusions:

• Radio Memory® software is a reliable tool for classifying lower third molars.
• It provides a valid alternative to direct orthopantomograph evaluation.
• The software is suitable for both clinical practice and research purposes.
