Clinical efficacy of various root canal obturating methods in primary teeth: a comparative study

Area of Science:

• Pediatric Dentistry
• Endodontics
• Dental Materials Science

Background:

• Primary teeth obturation is crucial for maintaining space and preventing complications.
• Various obturating techniques exist, each with potential advantages and disadvantages.
• Zinc oxide and iodoform paste (Endoflas F.S.) is a common material for primary teeth obturation.

Purpose of the Study:

• To compare the efficacy of four different obturating methods in primary teeth.
• To evaluate canal obturation quality and void presence using zinc oxide and iodoform paste.
• To determine the most effective obturation technique for primary teeth.

Main Methods:

• An in vivo study involving 29 patients (ages 3-9) and 64 primary teeth.
• Teeth were randomly assigned to four obturation groups: Lentulo spiral, pressure syringe, bi-directional spiral, and Pastinject.
• Post-operative evaluation assessed obturation quality (underfilled, optimally filled, overfilled) and void presence.

Main Results:

• Pastinject resulted in the highest number of optimally filled canals.
• Bi-directional spiral showed the most underfilled canals, while pressure syringe had the most overfilled canals.
• Pastinject and pressure syringe techniques exhibited the minimum number of voids.

Conclusions:

• Pastinject was identified as the most effective technique for obturating primary teeth.
• The findings provide evidence-based guidance for selecting obturation methods in pediatric endodontics.
• Further research may explore long-term outcomes of different obturation techniques.
