Objective: To compare the success rate of different obturation procedures in primary
mandibular second molars clinically and also by digital radiovisiography.
Methods: A total of 40 children aged between 4-8 years with deeply carious mandibular second
primary molars indicated for single session pulpectomy were selected. Canals were obturated with
Metapex. The 3 study groups (Endodontic plugger, Handheld lentulospiral, Navi Tip syringe) were
compared with the control group (reamer) both clinically and radiovisiographically. The data collected
were statistically analyzed using Pearson’s Chi-square and Fisher’s exact test.
Results: The use of Navi tip syringe led to the least number of voids followed by Endodontic plugger
and Reamer and the highest number of voids was reported with Lentulospiral. Navitip presented
maximum number of optimally filled cases followed by Endodontic plugger and Lentulospiral and
least number of optimally filled cases with reamer. However, there was no statistically significant
difference (p>0.05) in any of the groups with clinical (pain and tenderness to percussion) and radiographic
parameters (presence or absence of voids and length of obturation).
Conclusion: Within the limitations of the present study, though the clinical outcome was statistically
insignificant, Navitip syringe exhibited encouraging results and is a promising option for obturation
in primary teeth.
