Objectives:
Endodontic infections of posterior maxillary teeth sometimes spread to the maxillary sinus, generating severe complications. The aim of this study is to present the various problems encountered during endodontic treatment of these teeth.
Methods:
The files of 125 cases of odontogenic chronic maxillary sinusitis were reviewed retrospectively.
Results:
Chronic apical periodontitis was the cause in 99 cases and traumatising endodontic treatment in 26 cases. Foreign intra-sinusal bodies were occasionally seen as a consequence of different endodontic treatments of posterior maxillary teeth.
Conclusions:
A knowledge of dento-antral relationships is particularly important in the prevention of sinusal accidents and complications during various therapeutic manoeuvres, which should be performed according to and depending on the regional morphology.
