title: Complications after apicoectomy in maxillary premolar and molar teeth.
abstract: This study was designed to enumerate the number of perforations to the maxillary sinus while performing apicoectomy on maxillary premolar and molar teeth and to evaluate possible complications as a result of these perforations. A total of 472 apicoectomies were performed in 440 patients; perforations occurred in 10.4% of teeth, 23% in molars, 13% in second premolars and 2% in first premolars. No cases of acute or chronic sinusitis were recorded. It was concluded that apicoectomy, carried out using a meticulous surgical technique and proper postoperative care, should be considered as a treatment option before contemplating extraction.
