Visualization Enhancement of Dentinal Defects by Using Light-Emitting Diode Transillumination

Area of Science:

• Endodontics
• Dental Anatomy
• Diagnostic Imaging

Background:

• Dentinal defects are a concern in endodontic procedures.
• Previous research utilized root sectioning but may have limitations in defect visualization.
• The efficacy of light-emitting diode (LED) transillumination for defect detection is under investigation.

Purpose of the Study:

• To evaluate if LED transillumination enhances the visualization of dentinal defects.
• To compare defect detection rates using LED versus traditional non-LED root sectioning methods.

Main Methods:

• Forty mesial roots of mandibular molars were sectioned at 3, 6, and 9 mm from the apex.
• Specimens were examined with and without LED transillumination at varying magnifications.
• Two independent evaluators assessed and recorded dentinal defects; statistical analysis used the chi-squared test.

Main Results:

• The prevalence of dentinal defects increased significantly with LED transillumination (47.5%) compared to non-LED assessment (10%).
• At 3, 6, and 9 mm sections, LED evaluation detected defects in 20%, 25%, and 22.5% of specimens, respectively, versus 5%, 2.5%, and 2.5% without LED.
• The difference in defect detection rates between LED and non-LED methods was statistically significant (P < .05).

Conclusions:

• LED transillumination substantially improves the visualization and detection of dentinal defects in uninstrumented roots.
• Findings suggest that previous studies using conventional non-LED sectioning may have underestimated dentinal defect prevalence.
• The results advocate for the integration of LED transillumination in future studies and clinical assessments of dentinal defects.
