Evaluation of Quality of Obturation using Two Different Root Canal Drying Methods during Pulpectomy: A Randomized Clinical Trial

Abstract

Introduction: Drying the root canals in pulp therapy is often ignored, but is essential for a successful clinical outcome. Due to certain shortcomings of various root canal drying methods, a new Novel suction aspirator with apical broach was designed.

Objectives: To compare the effectiveness of drying the prepared root canals by Novel suction aspirator with apical broach and conventional paper points on quality of obturation using Coll and Sadrian criteria.

Methods: 20 children aged 5-8 years with prepared primary molar root canals indicated for pulpectomy were randomly divided into two groups based on drying method employed, Group 1- Novel Suction aspirator with apical broach and Group 2- Absorbent Paper points. After obturation with Metapex, the quality of obturation was determined using Coll and Sadrian criteria in both the groups. Chi-square test was used for comparing difference in proportions in two independent groups for qualitative variables.

Results: 80% teeth showed optimal filling with group 1 compared to 30% teeth in group 2 (p value=0.025). 90% teeth in group 1 showed no voids in obturation compared to 60% teeth in group 2 (p=0.021).

Conclusions: Significant results were found in Coll and Sadrian’s criteria of apical filling and voids criteria, concluding that a Novel suction aspirator with apical broach can be used as a more cheaper and effective alternative root canal drying technique to absorbent paper points.
