Quality of root fillings performed with four root filling techniques. An in vitro study using micro-CT.

Abstract

The main aim of the endodontic therapy consists of the tridimensional obturation of the endodontic space. The efforts for an ideally processed and sterilized root canal are questioned if the same is not obturated completely. The aim of this paper is to evaluate and determine the percentage of the volume of empty spaces and spaces of root canals obturated with different materials for obturation with the help of a microcomputer -tomography. This paper includes 80 frontal human extracted teeth. The teeth were divided in two bigger groups according to the technique of processing of the root canal: The first group consisted of 40 human single root teeth processed according to the standard technique of processing and obturated with gutta-flow and Thermafill. The second group consisted of 40 human single root teeth processed according to the ultrasonic technique of root canals processing and obturated with single cone and lateral compaction technique. Statistically significant differences have been registered between the root canals obturated with Thermafill and the Single cone technique (p<0.05). Statistically significant differences have been registered between the root canals obturated with GuttaFlow and the Single cone technique (p<0.01) and the Single cone and the technique of lateral condensation (p<0.01).
