This in vitro study assessed the quality of pulpectomies in primary incisors using three filling systems: syringe with

plastic needle, syringe with metal needle, and lentulo spiral. Preoperative radiographs of sixty extracted primary

incisors were taken, canals were prepared and obturated.Postoperative radiographs taken in two directions were

evaluated by two independent evaluators blinded to the technique used. Filling quality was determined by analyzing

radiopacity, presence of voids and amount of material in the canal. After statistical analysis, this study

showed that NaviTip system offered a more desirable filling quality than lentulo and Vitapex syringe techniques.
