[Root canal volume]

Area of Science:

• Dental materials science
• Endodontics
• Biomaterials engineering

Context:

• Root canal therapy aims to preserve tooth structure and function.
• Accurate assessment of root canal filling materials is crucial for predictable outcomes.
• Variations in tooth anatomy and obturation techniques can influence the final restoration's integrity.

Purpose:

• To quantify the weight increase (overload) of tooth roots after root canal obturation using lateral condensation with gutta-percha and Grossman's sealer.
• To determine the mean root canal volume and orifice diameter for different types of noncarious teeth.
• To provide data for understanding the impact of obturation on tooth structure.

Summary:

• 180 noncarious teeth underwent crown removal and root weighing before and after root canal obturation.
• The weight difference indicated the overload caused by gutta-percha and sealer.
• Mathematical calculations determined mean root canal volume and orifice diameter for each tooth group.

Impact:

• Provides quantitative data on the mass added during root canal filling.
• Contributes to understanding the biomechanical implications of obturation on tooth structure.
• Informs the development and selection of endodontic materials and techniques.
