“…There has been no previous report about endoscopic removal of a filling agent migrated from the root canal into the maxillary sinus. Migration through the maxillary sinus of a gutta percha point into the ethmoid sinus was described [3]. In our case, as in the case previously described, it is most likely that the endodontic cement went from the roots of the upper left first molar to the natural ostium by the action of the cilia that continue to clear mucus toward the natural ostium.…”

“…For instance, the displacement of an extruded gutta-percha point from a root canal to the ethmoid sinus has been previously reported. [10] The sinusitis symptoms were eliminated with surgical removal of the gutta-percha from the ethmoid sinuses. Our case also shows the displacement of two gutta-percha points from a root canal to the lingual periosteum.…”

“…En 9 de los cuales (5%) se identificaron en el interior del seno, como factor causal claro, distintos cuerpos extraños relacionados con algún tratamiento dental previo. La presencia de distintos objetos y sustancias desplazadas al seno maxilar, como factores irritantes desencadenantes de sinusitis maxilar, está ampliamente registrada: desde amalgama (16,17), gutapercha (18,19), remanentes de tubos de plástico de drenajes previos (20) e incluso agujas de sutura (21). Debido a que estos cuerpos extraños pueden desplazarse por el interior del seno maxilar y fijarse a su pared posterior, con el consiguiente riesgo de extensión intracraneal del proceso infeccioso, y con la dificultad añadida en su extracción del alto riesgo de hemorragia de esta área.…”
