Irreversible local sequelae of inadvertent extrusion of calcium hydroxide intra-canal medication:

a case report

C. J. Hanson, M. Macluskey

    Research output: Contribution to journalArticle

    Abstract

    Calcium hydroxide is a highly alkaline bacteriocidal intra-canal medicament.
    We present the case of a patient who developed anaesthesia of upper
    lip and cheek on the right side of her face following the placement of intracanal
    calcium hydroxide medicament into tooth 16 and the inadvertent
    extrusion of this paste. A route, along which the paste tracked, is proposed
    to account for the neural changes. The clinical presentation, radiographic
    investigations, treatment is outlined and discussed. The mechanism of toxicity
    of the paste is reviewed.
