Volumetric analysis of root fillings using spiral computed tomography: an in vitro study

Abstract

The greatest POV was obtained with System B and Thermafil. Voids were seen in all root fillings.

Micro-CT evaluation of the effectiveness of the combined use of rotary and hand instrumentation in removal of Resilon

“…The latter technique may require a smaller quantity of sealer and form a more homogenous mass than the former 12,25) . Hence, there would be a lesser amount of sealer to be eliminated and easier removal of the homogenous mass.…”

Contamination Of Gutta-Percha Cones In Clinical Use By Endodontic Specialists And General Practitioners

“…Justifying the presence of voids in root canal fillings without a sealer has frequently been pointed out by the literature, and this is a big problem. [23][24][25] Da Motta et al 25 claim that the simple environmental exposure of cones is not of critical importance.…”

“…Justificar la presencia de espacios en los sellantes del canal radicular sin aplicar un sellador ha sido señalado frecuentemente por la literatura, y esto es un problema grave. [23][24][25] Da Motta et al 25 señalan que la sola exposición de los conos al medio ambiente no es de mayor importancia. Sin embargo, nosotros hacemos énfasis en que debe respetarse el principio básico del control de la infección, pues diversos estudios han demostrado la contaminación microbiana durante la frecuente manipulación de los paquetes de gutapercha.…”

“…The microbial contamination observed in the present tests finds support among many studies, which also yielded the need for decontamination of gutta-percha immediately preceding the filling of root canals, especially studies investigating the presence of microbial contamination of guttapercha in unopened packages, 9,23,30,32 and other studies evaluating this contamination in packages already in clinical use. 23,30 En cuanto a las técnicas de detección de microorganismos utilizadas en el presente estudio, la principal ventaja del cultivo técnico es la naturaleza de la amplia gama que cubre, que puede identificar una gran variedad de especies en la muestra, aunque requiere mucho tiempo para la evaluación e identificación de bacterias insidiosas y exigentes.…”

Recent Advances in Endodontic Diagnosis: A Review

“…It is possible to determine the buccolingual and mesiodistal widths of the teeth and the presence or absence of root canal filling materials and metal posts. Anbu et al 7 evaluated the volumetric analysis of root filling using CT in 40 extracted maxillary central incisors obturated by lateral compaction, thermafill, obtura II, and system B. They found the greatest percentage of obturated volume was obtained with system B and thermafill.…”
