Evaluation of obturation techniques in primary teeth among Indians

TL;DR

This study compares four methods for filling root canals in children's teeth using a special imaging technique to determine which is most effective.

Contribution

The study evaluates obturation techniques in primary teeth using CBCT for the first time in an Indian population.

Findings

Lentulo spirals driven by a handpiece achieved the highest percentage of optimal root canal obturation.

Reamers showed a low percentage of optimally filled root canals.

Endodontic pressure syringe and reamers resulted in a high rate of overfilled canals.

Abstract

Evaluation of four distinct obturating methods namely endodontic pressure syringe (n=40), reamers (n=40), Lentulo spirals driven
through slow-speed handpiece (n=40) and incremental filling technique (n=4) using zinc oxide eugenol (ZOE) paste as obturating material
in deciduous teeth is of interest to dentist. Hence, we are interested determining the effective obturation methodology using CBCT.
Handpiece driven lentuspirals helped in optimum obturation in high percentage of root canals. Low percentage of optimally filled root
canals was observed in reamers technique. Moreover, under filled root canals was low in lentuspirals technique of obturation. Thus,
overfilled root canals were high in endodontic pressure syringe and reamers obturation technique.
