BACKGROUND AND AIM: Surgical endodontics may sometimes fail despite using root-end filling materials (REFMs). In this case report, a symptomatic right maxillary first premolar underwent periradicular surgery (PS) for replacing huge rate of amalgam with mineral trioxide aggregate (MTA).CASE REPORT: A thirty-year-old healthy woman attended with the chief complaint of recurrent swelling and absces...

This clinical report describes the delayed development of a maxillary second premolar. The premolar developed when the patient was between the ages of 12 and 16 years. The development of the tooth was discovered from a panoramic radiograph taken when the patient was 17 years, 1 month of age. Previous to this discovery, the tooth had been diagnosed as congenitally missing. The transition from th...

OBJECTIVE The aim of this study was to analyze tooth movement and arch width changes in maxillary dentition following nonextraction treatment with orthodontic mini-implant (OMI) anchorage in Class II division 1 malocclusions. METHODS Seventeen adult patients diagnosed with Angle's Class II division 1 malocclusion were treated by nonextraction with OMIs as anchorage for distalization of whole ...

accurate diagnosis of the root canal morphology and anatomy is essential for thorough shaping and cleaning of the entire root canal system and consequent successful treatment. this report describes a case of maxillary second premolar with two roots and three root canals (two mesial and distal palatal canals). the case report underlines the importance of complete knowledge about root canal morph...

Background: This study aimed to evaluate the cone-beam computed tomography (CBCT) technique considering its reliability diagnose resorption due maxillary impacted canine. Methods: In this cross-sectional study, 68 CBCT images were observed by two oral and maxillofacial radiologists. The position of canine was assessed, severity root in adjacent teeth determined rounds viewing. Finally, statisti...

The present study was carried out to observe root canal variations in maxillary and mandibular first premolar teeth in the local population using spiral computed tomography. Sixty, each of well formed maxillary and mandibular first premolar teeth without any carious lesions were used in this study. They were placed in 5% sodium hypochlorite solution for 30 minutes for the removal of organic deb...

INTRODUCTION It is imperative that the endodontic surgeon be knowledgeable of the anatomic dimensions of the surgical site. If cone-beam computed tomography is not available because of location/cost, it is prudent for the clinician to consult a knowledge base for the surgical site. An understanding of the root thickness of maxillary premolars and molars at the preferred level for root resection...

A 40-year-old man suffered from a repeatedly recurrent desmoplastic ameloblastoma in the right maxillary anterior and premolar regions. During the first visit, the patient was provisionally histopathologically diagnosed with a developmental cyst, and it was confirmed to be unicystic ameloblastoma and resected. Four years later, the lesion recurred, and was diagnosed as a desmoplastic type of am...
