Comparative Evaluation of Obturation Quality Using Three Different Obturation Techniques in Primary Teeth: A Conebeam...

Area of Science:

• Pediatric Dentistry
• Endodontics
• Dental Materials Science

Background:

• Pulpectomy is crucial for irreversibly damaged primary teeth.
• Successful endodontic treatment relies on effective biomechanical preparation and obturation.
• Minimizing voids and achieving a hermetic seal are critical for long-term success.

Purpose of the Study:

• To compare the root canal obturation quality of three techniques: Lentulo Spiral, Pastinject, and Dispo Van syringe.
• To evaluate void presence in primary teeth following pulpectomy using cone-beam computed tomography (CBCT).

Main Methods:

• Sixty primary tooth root canals (age 4-7 years) indicated for pulpectomy were divided into three groups.
• Endoflas was used for obturation with Lentulo Spiral, Pastinject, and Dispo Van syringe.
• Postoperative CBCT scanning assessed obturation quality and void presence.

Main Results:

• Pastinject showed significantly fewer voids, indicating superior obturation quality.
• Lentulo Spiral and Dispo Van syringe exhibited more voids compared to Pastinject.
• The study evaluated obturation success rates using statistical analysis.

Conclusions:

• Pastinject is the most effective technique for obturating primary teeth.
• Optimal obturation quality is essential for successful primary tooth pulpectomy.
• CBCT is a valuable tool for assessing endodontic treatment outcomes.
