Abstract

Aim: To predetermine the mass of obturating material required to obturate primary maxillary and mandibular first and second molars. To evaluate the obturation quality of primary mandibular second molar obturated using the predetermined obturation quantity. Materials and methods: The formula mass = root canal volume × density was used to calculate the quantity of obturating material for each tooth. The average root canal volume was calculated using pre-existing cone-beam computed tomography (CBCT) scans (n = 30) of children aged between 4 and 9 years. Pulpectomy was performed in mandibular second molar and obturated with pre-determined quantity of obturating material. The quality of obturation was assessed in terms of over-obturation, under-obturation and optimal obturation. Results: Optimal obturation was obtained in 43.3%, under-obturation was observed in 30% and over-obturation was observed in 26.7% Conclusion: Obturating the primary root canals by predetermining the mass of obturating material will reduce the wastage of material (metapex) and cross-contamination of the material.
