Abstract:
The purpose of this study was to measure the ability of a thermoplasticized-injectable (TPI) gutta-percha (GP) delivery system to fill a prepared root canal to working length and replicate intracanal defects (coronal, middle, apical) as a function of root canal preparations with varying lateral dimensions. Three split-tooth models with 0.06 taper and different apical gauge preparations, 0.30 mm (group A), 0.40 mm (group B), and 0.50 mm (group C), were used. Obturations were evaluated using an ordinal scale (0-4) based on how much each intracanal defect was replicated. Coronal and middle defects were completely replicated 100% of the time, regardless of the preparation. However, there was a significant difference (p
