Aims and objectives: Pulpectomy is one of the most commonly rendered treatment modalities in primary teeth wherein the pulp is irreversibly inflamed. To evaluate the sufficiency of calculated obturating material and quality of obturation in primary teeth using an obturagun device.
Materials and methods: Average root canal volume of 65 and 75 was calculated from cone beam computed tomography (CBCT) scans of children in the age-group of 5–9 years. Based on the average root canal volume and density of obturating material (Vitapex), quantity of obturating material required to obturate a single primary mandibular second molar was calculated. Computer-aided design (CAD)/computer-aided manufacturing (CAM) software was used to design obturagun, which was three-dimensional (3D) printed for study purposes. An in vitro pilot study (pulpectomy) was conducted on 20 extracted primary mandibular second molar to evaluate the efficacy of the obturagun.
Results: Average root canal volume of 75 was larger than 65. Approximately 68% of the root canals showed optimal obturation. Distal root canals were more void free as compared to mesial. In 70% of the cases, the calculated obturation material was sufficient to obturate a single primary mandibular second molar.
Conclusion and clinical significance: Average root canal volume can be used to determine the quantity of obturating material. Obturagun can be used as an alternate obturating technique for primary teeth.
