Calcium hydroxide paste in the maxillary sinus: a case report

Abstract

A case is reported in which a perforation of the sinus floor of the maxillary sinus occurred with extrusion of a calcium hydroxide paste during routine root canal treatment of a maxillary premolar. All clinical manifestations are described as well as the results of a follow-up evaluation.

Removal of Calcium Hydroxide Paste Leaked Into the Maxillary Sinus

“…9 However, a radiopaque calcium hydroxide paste remained after 1 year of endodontic treatment. 10 In addition, the histopathological changes of the sinus mucosa caused by direct contact with calcium hydroxide paste are still unclear. In the present study, unlike previous reports, the patient complained of maxillary sinusitis and pain at the related tooth, for which we performed surgical treatment for the removal of leaked calcium hydroxide paste.…”

Necrosis of the gingiva caused by calcium hydroxide: a case report

“…On the other hand, Fava (1993) described a case of overfilling of the palatal root canal of a maxillary right first premolar leading to Ca(OH) 2 in the maxillary sinus. The patient experienced some pain, but 4 days later the symptoms had decreased to a minimum.…”

Management of third molar teeth from an endodontic perspective

“…[54,63,64] Avoid chemical/pressure irritation Perforation of the maxillary sinus by gutta-percha or silver cones, as well as injection of calcium hydroxide medicament into the sinus has been reported to cause various inflammatory responses. [49,65,66] In addition, the extrusion of sealer and/or gutta-percha into the mandibular canal space is the most common cause for post-operative toxic reactions in the mandibular canal ranging from mild inflammatory reactions to ischemia and disabling sensory disturbances, such as paresthesia, dysesthesia and anesthesia, which may become permanent. [67][68][69][70] Indeed, the extrusion of toxic chemicals, such as paraformaldehyde containing pastes, calcium hydroxide medicament and eugenol based sealers, would cause more damage and delay of the recovery potential.…”
