Double tooth is a dental anomaly consequent to fusion of two or more teeth or gemination of a single tooth. This report describes a unique case of double tooth in relation to a mandibular lateral incisor exhibiting the presence of four root canals. The role of conventional radiography and advanced three-dimensional imaging techniques in the better assessment of complex root canal systems and th...

Concrescence, Fusion, Gemination and twinning are developmental anomalies that modify the shape of the teeth. Gemination refers to the attempt at division of a toothgerm, resulting in formation of single large tooth, with groove or notch in the crown. Except gemination , others arise as a result of union of two toothgerms or tooth. This article is an illustration of case report of Gemination of...

OBJECTIVE The objectives of the present study were to investigate the prevalence and characteristics of supernumerary teeth in a patient sample of Nepalese children. STUDY DESIGN A survey was performed on 2684 patients (1829 females and 1035 males) ranging in age from 6 to 14 for the presence of supernumerary teeth. For each patient with supernumerary teeth the demographic variables (age and ...

The aim of this case report is to describe the treatment of a patient with skeletal Class III malocclusion with maxillary retrognathia using skeletal anchorage devices and intermaxillary elastics. Miniplates were inserted between the mandibular lateral incisor and canine teeth on both sides in a male patient aged 14 years 5 months. Self-drilling mini-implants (1.6 mm diameter, 10 mm length) wer...

An unerupted supernumerary tooth was attached to the root surface of an unerupted permanent lateral incisor. It was necessary to remove both the supernumerary and the permanent lateral incisor as a single unit. The permanent lateral incisor was separated from the supernumerary and placed back into the original developmental crypt. The replanted lateral incisor erupted normally one year later. W...

UNLABELLED New radiographic maxillofacial techniques, cone beam computerized tomography (CBCT) are a necessity in the assessment of jaw bone offer to effectively evaluate the treatment. AIM To quantitatively and qualitatively evaluate anterior mandibular area on CBCT comparing to orthopantomography (OPG). MATERIAL AND METHODS Fifty-one dental patients, aged between 20 and 77 years, were qua...

PURPOSE The purpose of this study was to examine the patient- and treatment-related etiologic factors of external root resorption. MATERIALS AND METHODS This study consisted of 163 patients who had completed orthodontic treatments and taken the pre- and post-treatment panoramic and lateral cephalometric radiographs. The length of tooth was measured from the tooth apex to the incisal edge or c...

Background and purpose: Accurate instance segmentation of teeth in panoramic dental X-rays is a challenging task due to variations tooth morphology overlapping regions. In this study, we propose new algorithm, for instance, the different X-rays. Methods: An model was trained using architecture Mask Region-based Convolutional Neural Network (Mask-RCNN). The data training, validation, testing wer...

Previous research into the origins of lower incisor crowding have not yet established the part played by skeletal morphology in its development. Longitudinal cephalometric records of twelve cases with spaced lower teeth were compared with those of twelve moderately crowded cases and twelve severely crowded cases. Significant differences were found between the three groups. These suggested that ...
