CHRONIC SINUSITIS AND ZINC-CONTAINING ENDODONTIC OBTURATING PASTES

Several researchers have reported a link between the development of a solitary antral aspergillus sinusitis and the presence of zinc-contain ing root canal obturating paste within the antrum. If diagnosed correc tly, it is generally accepted that this type of sinusitis can be treat ed effectively using surgical techniques alone. However, previous repo rts have shown that this is not always the case and may result in prol onged and inappropriate treatment of the condition. It is hoped that t he reported case and literature review will assist both dental and med ical practitioners in identifying affected patients and in the subsequ ent instigation of correct treatment regimes.
