ABSTRACT

Gutta-percha is chemically an Isoprene-based polymer, impervious, non-porous and radiopaque, among other characteristics, used since the 19th century, it manifests some disadvantages inherent to the material, which has led to the birth of new materials with improved properties. Recently, a novel material based on optical fiber covered by silver nanoparticles (FONP) has been developed, characterized and proposed as an alternative material for root canal obturation. In the present study, 24 teeth were selected and divided into four comparative experimental groups for obturation with fiber optics and gutta-percha, both with the AH Plus sealer. The roots were sealed in groups of ten and stored in saline at 37 oC. Apical filtration test was performed from the apical end of the material interface to the most coronal extension of the dye observed microscopically. The LAS EZ V3.0 tool was used to make the measurements and the data was tabulated and analyzed. Results: Measurements of microfiltration at the apical and intracanal level showed differences in favor of gutta-percha, where the experimental groups showed an average filtration of 0.872 mm in the Gutapercha/AH-PLUS group and 2.390 mm using FONP/AH-PLUS, even so, it was evidenced that the sealing properties of the optical fiber with nanoparticles are sufficient to consider this material as a proper filling material for dental root canals as a substitute for gutta-percha.
