In this article, we report a case of retained gutta-percha in the maxillary sinus resulting in chronic sinusitis.
متن کاملApical sealing ability of Resilon/Epiphany versus gutta-percha/AH Plus: immediate and 16-months leakage.
AIM To compare the long-term apical sealing ability of gutta-percha/AH Plus and Resilon/Epiphany. METHODOLOGY The root canals of 90 single-rooted human mandibular premolars with single narrow root canals were prepared with ProFile 0.4 taper instruments to apical size 40. After each instrument, the canals were irrigated with 1% sodium hypochlorite. Subsequently, the teeth were randomly divided...
متن کاملIn vitro comparison of three different lengths of remaining gutta-percha for establishment of apical seal after post-space preparation.
The quality of apical seal with regard to the length of remaining gutta-percha following post-space preparation is still controversial. The purpose of this in vitro study was to compare three different lengths of remaining gutta-percha for apical seal after post-space preparation. A total of 126 single-rooted extracted maxillary human anterior teeth with intact apices, straight roots, and witho...
متن کاملSurgical resolution of chronic tissue irritation caused by extruded endodontic filling material.
Controversy remains regarding the relative toxicity versus inertness of endodontic filling materials, including gutta-percha, in vital tissues.We discuss reaction to and possible toxicity of gutta-percha and sealers and present 2 cases of symptomatic chronic inflammatory reaction where gutta-percha and associated filling materials were found to have extruded past the confinement of the root str...
متن کاملLong-term sealing ability of GuttaFlow versus Ah Plus using different obturation techniques.
OBJECTIVE To compare the long-term sealing ability of GuttaFlow® using different obturation techniques. STUDY DESIGN Three hundred teeth, prepared with a crown-down technique, were divided into thirty experimental groups (n=10) to evaluate the apical and coronal leakage, at 3, 30 and 120 days, of lateral compaction gutta-percha+AH Plus TM, lateral compaction gutta-percha+GuttaFlow®, single co...
