[Canal obturation technic. Stereomicroscopic and SEM study]

Area of Science:

• Endodontic materials science
• Dental restorative techniques

Background:

• Effective root canal obturation is crucial for endodontic treatment success.
• Various filling techniques exist, each with potential advantages and disadvantages.

Purpose of the Study:

• To compare the effectiveness of four different root canal filling methods.
• To evaluate the quality of gutta-percha and cement seal using microscopy.

Main Methods:

• Four obturation techniques were compared in 32 monoradicular teeth.
• Teeth were sectioned at 2, 5, and 8 mm from the apex for analysis.
• Stereo and scanning electron microscopy were employed for evaluation.

Main Results:

• Thermomechanical condensation demonstrated superior sealing capabilities.
• Vertical and lateral condensation techniques also yielded good results.
• The single-cone method showed variable and less consistent outcomes.

Conclusions:

• Thermomechanical condensation is a highly effective method for root canal obturation.
• Vertical and lateral condensation offer reliable alternatives.
• The single-cone technique may require further optimization for consistent results.
