Objective: To compare the success rate of different obturation procedures in primary mandibular second molars clinically and also
by digital radiovisiography.
Method: 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 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 least number of voids followed by Endodontic plugger and Reamer and highest number
of voids were 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 group in relation to 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 clinical outcome was statistically insignificant, Navitip syringe
exhibited encouraging results and is definitely a promising option for obturation in primary teeth.
