introduction: ectopic tooth eruption may result owing to one of 3 processes: developmentaldisturbance, iatrogenic activity, or pathologic process, such as a tumor or a cyst. in rare cases, occlusion of the sinus ostia may predispose a patient to develop a maxillary sinus mucocele. when the maxillary sinus is invaded, symptoms usually occur late in the process.   case report: a 17 years old boy ...

Oroantral fistula (OAF) is an abnormal connection between the oral cavity and maxillary sinuses. This pathology develops when oroantral communicant fails to close spontaneously; thus, it remains patent epithelialized. If not treated immediately, this condition might be passage for bacteria enter sinuses, causing infection, sinusitis, or delayed healing. Consideration of OAF therapy should consi...
