AIM The purpose of this study was to verify the association between the facial type and the morphology of the upper central incisor, to potentially provide a guide for artificial tooth selection in esthetic and prosthetic rehabilitation. MATERIALS AND METHODS The sample consisted of 51 lateral teleradiographs (lateral cephalometric radiographs) and cast models of subjects with a naturally opt...

Incisors are the most frequently involved teeth to suffer dental trauma, with root fractures occurring in 3% of injuries due to dental trauma. Horizontal root fractures mostly affect upper central incisors, mainly in the middle third of the root. Nevertheless, apical and coronal third fractures are also sometimes reported. This case report presents the five-year follow-up of a 16-year-old male ...

AIM The aim of this report was to show the management of a case with an impacted central maxillary incisor caused by odontoma in a young patient with two mesiodentes in the region of the nasal floor. CASE REPORT A 9-year-old girl was seen in the Department of Orthodontics of the University of Rome 'Tor Vergata'. Radiographic images showed intraosseous impaction of the maxillary right central ...

When a primary tooth sustains a traumatic injury, development of the permanent tooth can be disturbed, leading to various malformations. This case report details the 7-year follow-up of a developmental anomaly of a central mandibular incisor in a 10-year-old Japanese girl with a history of dental trauma that had occurred at age 4. The trauma had resulted in unusual crown dilaceration in the per...

We investigated the distribution of cortical, callosal, and thalamic connections from the primary somatosensory area (S1) in naked mole-rats, concentrating on lower incisor and forelimb representations. A neuronal tracer (WGA-HRP) was injected into the center of each respective representation under guidance from microelectrode recordings of neuronal activity. The locations of cells and terminal...

Adult dentoalveolar trauma most often occurs in the context of sports activities and traffic accidents. Coronal fractures are the most common type of lesion, followed by tooth luxation. We present the case of a 25-year-old woman who suffered alveolar bone damage and coronal fractures of the upper incisors, with extrusive luxation of the right central incisor, as the result of a fall. On the fir...

Autotransplantation of teeth has been reported by many authors to replace missing teeth, either posterior or anterior, where it became a realistic treatment alternative and useful routine procedure for replacement of teeth in young adolescents where the implant option is relatively contraindicated, particularly to replace teeth lost due to trauma. This paper presents fourteen years old boy, who...

conclusions the treatment reported for reattachment of the tooth fractures and post and core techniques are reasonably easy while providing immediate and lasting results in patients’ regaining of social confidence and functionality. introduction the fracture of front teeth is one of the routine presentations of traumatic injuries. the treatment of a fractured tooth involving the pulp includes r...

The purpose of the study was to investigate the relationship between incisor and condyle movement during protrusion in children with primary dentition. Subjects were categorized into two age groups. A primary dentition group consisted of 20 children and a permanent dentition group consisted of 25 women. The occlusions and TMJs in both groups were normal, with no history of orthodontic treatment...
