The evaluation of apicectomy without retrograde filling in terms of lesion size localization and approximation to the anatomic structures

The purpose of this study was to evaluate of the patients who underwent apical resection. Besides assess the classification of resection side, localization, lesion size, approximation of anatomic structures and the purpose of the apical surgery retrospectively. In this stutdy 782 patients and 1191 apical resection applied tooth evaluated. 504 of the patients were famale and 278 were male. Patients age was between 13 and 76 years old and operated between January 2016 and January 2017. The study includes incisor, canine and premolar teeth which had the apical resection as the first time. Operation side evaluated from orthopantomograph and periapical radiographs. There were 1191 teeth operated and 966 of them in maxilla and 225 of them in mandible. The number of the incisor teeth were 871, 177 were canine, 129 were premolar and one of them was molar. The total amount of 468 patients had operated by just 1 tooth, 454 of the operated teeth had cyst on the operation side. Premolar and molar side 21 of the 93 lesion had approximation with maxillar sinus. On the other hand in maxilla 39 of 569 lesion had approximation with nasal cavity. In mandibula 1 of the 15 lesion, which involved mandibular premolar teeth, had approximation with mental foramen. Apical resection operation mostly done for one tooth, and the lesion size was less than 10 milimeters. Furthermore apical resection mostly done for incisors cause of odontogenic cyst.
