Volumetric Analysis of Different Obturating Techniques Using CBCT: An In-vivo Study

Area of Science:

• Endodontic therapy
• Dental materials science

Background:

• Root canal obturation is vital for preventing endodontic reinfection and ensuring long-term treatment success.
• Effective sealing of the root canal system prevents microbial invasion and reduces recurrent infection risk.
• Several obturation techniques exist, each with unique pros and cons regarding material adaptation, application, and void formation.

Purpose of the Study:

• To conduct a volumetric examination of four root canal obturation techniques.
• To assess the material's ability to fill root canal space using Cone Beam Computed Tomography (CBCT).
• To identify voids that could compromise obturation effectiveness.

Main Methods:

• Utilized Cone Beam Computed Tomography (CBCT) for volumetric analysis.
• Evaluated four distinct root canal obturation techniques.
• Assessed void formation and material adaptation within the root canal system.

Main Results:

• Cold Lateral Condensation, though cost-effective, may lead to voids due to gutta-percha cone gaps.
• Carrier-Based and Thermoplasticized Injectable techniques show improved adaptation and reduced void potential.
• Technique selection involves balancing cost, ease of use, and sealing efficacy.

Conclusions:

• Effective root canal sealing is paramount for therapeutic success.
• The choice of obturation technique significantly impacts the prevention of reinfection.
• Optimizing technique selection minimizes voids and enhances long-term endodontic outcomes.
