A resin embedding method for transparent teeth with ink-infiltrated pulp cavities

Area of Science:

• Dental Anatomy
• Materials Science in Dentistry
• Endodontic Research

Background:

• Classical methods for preparing transparent teeth involve observation within capped glass bottles.
• These traditional methods limit manual handling and free observation angles.
• Investigating root canal morphology requires clear visualization and accessible specimen handling.

Purpose of the Study:

• To evaluate the convenience of resin-embedded transparent teeth compared to classical transparent teeth.
• To assess the suitability of resin embedding for detailed morphological studies of root canals.
• To introduce a novel method for preparing transparent teeth for endodontic research.

Main Methods:

• Demineralized human teeth were sectioned into coronal and radical portions.
• Pulp tissue was removed, and ink was injected into the pulp chamber and root canals.
• Teeth were dehydrated, rendered transparent using methyl salicylate, and embedded in polyester resin.

Main Results:

• Resin-embedded teeth retained transparency, clearly displaying ink-stained root canal morphology.
• Specimens allowed for manual handling and observation from all angles.
• The resin embedding method proved superior to classical methods for specimen accessibility and visualization.

Conclusions:

• Resin embedding provides a more convenient and effective method for preparing transparent teeth.
• This technique significantly improves the ability to investigate root canal morphology.
• The novel method offers enhanced detail and handling for dental research and education.
