Abstract

|
The immediate relationship between the maxillary molar root tip and the maxillary sinus floor is the cause of displacement of the root tip into the maxillary sinus. Moreover, sometimes the molar roots are widely separated, resulting in a high rate of root fracture during extraction. Accidently root fragments could be displaced into the maxillary sinus and when happened, retrieval of the root should be done urgently because of several complications such as oroantral communications, sinusitis, antrolith, and mucocele. In this case report, we introduce the root tips that have displaced into the maxillary sinus. In addition, we would like to discuss some considerations about some signs such as root projection into the maxillary sinus or darkening sign on the root apex that the surgeon can prevent displacement of root tip into the maxillary sinus before extraction.
