Pulpectomies in primary incisors using three delivery systems: an in vitro study

Area of Science:

• Pediatric Dentistry
• Endodontics
• Dental Materials Science

Background:

• Pulpectomy is a crucial root canal treatment for primary teeth.
• Effective canal filling is essential for successful pulpectomy outcomes.
• Evaluating different filling systems is vital for optimizing pediatric endodontic procedures.

Purpose of the Study:

• To compare the quality of pulpectomy fillings in primary incisors using three distinct delivery systems.
• To evaluate the efficacy of the NaviTip system against traditional lentulo spirals and syringe techniques.

Main Methods:

• An in vitro study involving sixty extracted primary incisors.
• Canals were prepared and filled using syringe with plastic needle, syringe with metal needle, and lentulo spiral systems.
• Postoperative radiographs were analyzed by blinded evaluators for radiopacity, voids, and material fill.

Main Results:

• The NaviTip system resulted in a more desirable filling quality.
• Compared to lentulo spirals and the Vitapex syringe technique, NaviTip showed better radiopacity and fewer voids.
• Quantitative analysis of canal fill indicated superior performance of the NaviTip system.

Conclusions:

• The NaviTip system is a more effective method for obturating primary incisor root canals compared to lentulo and Vitapex syringe techniques.
• Improved filling quality with NaviTip may lead to better long-term outcomes in pediatric pulpectomy.
• Further clinical studies are warranted to confirm these in vitro findings.
