Revisit of endodontic pressure syringe obturation technique – pulpectomy procedures in necrotic primary molars

Aim: The aim of the study is to evaluate the efficiency of hand held lentulospiral (HHL) and endodontic pressure syringe techniques in primary molar radiographically using endoflas obturating material. Background: Successful endodontic therapy needs preparation of an aseptic root canal and sealing of the root canal system. Many investigations have been carried out to evaluate and compare the success rate of obturating techniques for primary teeth and major research in the area of finding newer obturating techniques is ongoing. The literature regarding the comparison of comparative efficiency of hand held lentulospiral and endodontic pressure syringe is relatively sparse. Therefore the present clinical study is undertaken to radiographically compare, the primary teeth obturation with hand held lentulospiral and endodontic pressure syringe. Study design: The present study was conducted on twenty primary molars indicated for pulpectomy in the age groups between 4 to 8 years. The teeth were randomly divided into two groups (group I and II). Group I (control group) obturated with hand-held Lentulo spiral and group II (test group) obturated with endodontic pressure syringe respectively. Post-operative evaluation was done for: a) quality of canal obturation, (under fill, optimally fill, or overfill) and b) presence of voids in each third of the root canal. The obtained data were analyzed using Chi-square test and Mann Whitney U test. Results: The results of the present study showed 50% of the canals were optimally filled, 40% were overfilled and 10% were under filled in control group. In test group were filled using endodontic pressure syringe showed, 70% of canals were optimally filled, 30% of canals were overfilled and there was no underfilled canals. The present study also showed higher number of voids in the middle 1/3rd of the control group than in the test group. There was no statistically significant difference between both the techniques. Conclusion: The obturation of primary molar teeth using hand held lentulospiral and endodontic pressure syringe though showed presence of voids in both the groups did not significantly affect the quality of root canal fillings.
