Tooth transposition can be described as interchange in position of two adjacent permanent teeth the same quadrant. A case with a maxillary dilacerated central and tranposition canine-lateral incisor, treated forced eruption piezosurgical technique to shorter treatment time. Treatment is challenging for both orthodontists oral surgeons. Using cone-beam computed tomography necessary correct local...

This case report describes the anomalous development of maxillary permanent lateral incisors in a seven-year-old white male. The maxillary right permanent lateral incisor radiographically demonstrated anomalous development characteristic of dens invaginatus. A coincidental finding of a microdontic maxillary left permanent lateral incisor also was observed at this time. This patient presented wi...

T canines have the highest reported incidence of dental transposition—most commonly with the first premolar, followed by the lateral incisor.1-8 Several authors have described cases in which canine transpositions were resolved or the teeth were aligned in their transposed positions. 9-11 To our knowledge, however, no one has reported treating a patient in whom bilaterally impacted upper canines...

Implant restorations have become a primary treatment option for the replacement of congenitally missing lateral incisors. The central incisor and canine often erupt in less than optimal positions adjacent to the edentulous lateral incisor space, and therefore preprosthetic orthodontic treatment is frequently required. Derotation of the central incisor and canine, space closure and correction of...

The purpose of this study was to determine the severity of gingival margin discrepancy affecting the mandibular incisors in children with a single-tooth anterior crossbite. The response of the position of the gingival margin to correction of the crossbite also was investigated. Twenty-two subjects with a single central crossbite and 16 subjects with a single lateral crossbite were identified fr...

This research used the spectroradiometer (Pritchard Model 1980 B) to measure the spectral radiance factors of women's maxillary anterior teeth. The following conclusions were reached: 1. The spectral distributions of the anterior teeth were all similar at the cervical, middle, and incisal areas respectively. Their spectral distributions ran in parallel at an almost equal distance, with the curv...

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...

Open bite (OB) is a generalized term, which could incorporate subgroups that react differently to vertical correction. The objectives of the present study were to detect vertical treatment changes in incomplete bite (IB: inter-incisor overlap with no lower incisor contact with teeth or palate) and OB (no inter-incisor overlap) groups compared with a complete bite (CB: inter-incisor overlap with...

OBJECTIVE To assess the prevalence of lateral incisor agenesis impacted canines and supernumerary teeth in a young adult male population. MATERIALS AND METHODS The panoramic radiographs of 1745 military students (mean age: 18.6 ± 0.52 years) who attended the Center of Aviation Medicine of the Armed Forces of Greece during the period 1997-2011 were initially analyzed for lateral incisor agenes...
