Abstract
Context:
Three-dimensional seal of the root canal space has always been challenging. The incorporation of gutta-percha and sealer prevents microleakage by bacteria, ensuring a shielded root canal space. However, the penetration of sealer to various depths within the root canal has always been looked with curiosity.
Aims:
Thus, the present in vitro study was undertaken to evaluate the percentage and average depth of penetration of Endoflas F. S., AH Plus, and Epiphany sealers into dentinal tubules among the coronal, middle, and apical thirds of the roots following obturation with a lateral compaction technique using Confocal Laser Scanning Microscopy.
Settings and Design:
The study is an in vitro randomized control trial.
Subjects and Methods:
Thirty sound central incisors were decoronated at the level of the cementoenamel junction. Working length determination was done followed by a meticulous cleaning, shaping, and under copious irrigation. The teeth were then randomly divided into three groups: Endoflas FS sealer, AH Plus sealer, and Epiphany sealer. On fluorescence treatment, the teeth were sectioned at the midpoint of coronal, middle, and apical third of each root and viewed under confocal laser scanning microscope.
Statistical Analysis Used:
The results were analyzed using one-way ANOVA, and the significant difference between groups was analyzed with post hoc Tukey test.
Results:
Epiphany sealer provided with better percentage and depth penetration in comparison to Endoflas FS and AH Plus sealers. Furthermore, the coronal third of the root had better percentage and sealer penetration than the middle and apical thirds.
Conclusions:
Sealers tend to provide a firm bond between the tooth and the gutta-percha. They bind, lubricate, and seal the gutta-percha cones to fill the accessory canals. Within the limitations of this study, the superior flow and enhanced setting time Epihany sealers provide better percentage and depth of penetration than AH Plus and Endoflas FS.
