Macrodontia is a rare dental anomaly that refers to teeth that appear larger than normal. Generalised macrodontia can be associated with certain medical conditions and syndromes. This case report presents clinical and radiographic findings of isolated bilateral macrodontia in a 14-year-old child. The patient was referred to the clinic with local crowding of maxillary and mandibular teeth. Radio...
The purpose of this study was to compare the success rates of Class II subdivision malocclusion patients treated with either symmetric or asymmetric extractions. The sample consisted of 51 patients with Class II subdivision malocclusion. The patients were divided into 2 groups. Group 1 included 28 patients who were treated with 4 premolar extractions. The 23 patients in group 2 were treated wit...
OBJECTIVES Anterior maxilla, known as the esthetic zone, plays an important role in facial and smile esthetics. This study assessed the frequency of implant treatments in the esthetic zone of patients presenting to Dental Implant Department of Tehran University during 2002-2012. MATERIALS AND METHODS This descriptive study was conducted on dental records of patients receiving implant treatmen...
Ankylosis of primary mandibular molars has been routinely found to be associated with various developmental disturbances in permanent dentition such as aplasia of the succedaneous tooth, ectopic eruption of the premolar, infraoclusion of the ankylosed tooth leading to tipping of the first permanent molar etc. This article describes a rare case where there was ankylosis of a mandibular second pr...
Overeruption of maxillary molars due loss of opposing teeth creates occlusal and functional interferences. Before reconstruction can be initiated, intrusion of overerupted molars becomes essential. This report illustrates treatment of overerupted maxillary premolar and molar via direct use of miniscrew anchorage. A 24-year old female had lost first and second left mandibular molars due to pulpa...
Long-term success of endodontic treatment is strictly dependent on proper shaping and cleaning of the root canal system followed by obturation of entire prepared space. Anatomical variations should be considered during radiographic and clinical evaluation as parts of endodontic treatment. A mandibular premolar with three canals is quite rare and such a tooth requires special canal preparation a...
Evaluation of mandibular cortical bone thickness for placement of temporary anchorage devices (TADs)
OBJECTIVE In this study, we measured the cortical bone thickness in the mandibular buccal and lingual areas using computed tomography in order to evaluate the suitability of these areas for application of temporary anchorage devices (TADs) and to suggest a clinical guide for TADs. METHODS The buccal and lingual cortical bone thickness was measured in 15 men and 15 women. Bone thickness was me...
History and Physical Examination Findings A 2-year-old 32-kg (70.5 lb) spayed female mixed-breed dog was referred to the Animal Hospital of Verona for evaluation of a cystic lesion of the oral cavity. Previous examination had not yielded a definitive diagnosis. Oral examination revealed a purple to pink swelling approximately 15 X 20 X 11 mm involving the dorsal aspect of the left mandible in t...
Background: A correct diagnosis of the morphology of the root canal system is crucial in order to ensure a successful root canal treatment. The incidence of mandibular first premolars with three root canals has been reported to be low. This clinical case report describes a case of a successful nonsurgical endodontic management of a mandibular first premolar with three root canals. Case present...
BACKGROUND This study cephalometrically compared the dentoskeletal and soft tissue changes consequent to one and three-premolar extraction protocols of class II subdivision malocclusion treatment. METHODS A sample of 126 lateral cephalometric radiographs from 63 patients was selected and divided into two groups. Group 1 consisted of 31 type 1 class II subdivision malocclusion patients treated...
