cone beam computed tomography is a useful technique for imaging the craniofacial lesions. it produces more realistic images that facilitate interpretation. juvenile ossifying fibroma (jof) is a rare and benign fibro-osseous neoplasm that arises within the craniofacial bones, especially in the maxilla. mandibular lesions can be seen in 10% of the cases.in both jaws, it has a predilection for the...

Disturbances of tooth development may result in anomalies which appear in the form of swelling of the overlying mucosa of the erupting deciduous or permanent teeth, mostly in children. Eruption cyst (EC), a benign cyst is one such lesion associated with erupting teeth. ECs usually present as solitary swellings on the alveolar ridge mucosa, whereas multiple ECs presenting simultaneously or in sh...

Odontomas are the commonest odontogenic tumors of the oral cavity and are by nature asymptomatic. They consist mainly of dental tissue that may or may not be arranged in an orderly fashion. Their presence is often detected accidentally or due to the presence of a dental disturbance such as an unerupted tooth. The very rarity of odontomas erupting into the oral cavity validates the need for more...

We present the unusual case of a large complex odontoma erupting in the maxilla. Odontomas are benign developmental tumours of odontogenic origin. They are characterized by slow growth and nonaggressive behaviour. Complex odontomas, which erupt, are rare. They are usually asymptomatic and are identified on routine radiograph but may present with erosion into the oral cavity with subsequent cell...

Calcifying cystic odontogenic tumor is an uncommon odontogenic neoplasm which is included in the heterogenous group of lesions under a broader description of Ghost cell odontogenic tumors. All these lesions have the presence of ghost cells as a common feature. Calcifying cystic odontogenic tumor is a unique lesion with variable biologic behaviour and found to occur with other odontogenic tumour...

BACKGROUND Peripheral odontoma arising in the extraosseous soft tissues is rare and if not removed early, may enlarge over time and eventually erupt in the oral cavity. CASE PRESENTATION A 15-year-old girl presented with "denticles on the gingiva". During the intraoral examination, seven small tooth-like structures were found. These were exposed in the anterior left gingiva between the perman...

Starquakes probably occur in rapidly spinning or ultra high field neutron stars. In this article, we argue that highly compressed gas containing electron-positron pairs could evaporate and erupt from inside the star when a crack forms then heals during starquake. Under influence of existing oscillation modes star, may have sufficiently large size long lifetime. An appropriate amount can into ma...

Abstract In this study, we present the magnetic configuration of an erupting pseudostreamer observed on 2015 April 19, southwest limb Sun, with a prominence cavity embedded inside. The eruption resulted in partial halo coronal mass ejection. begins slow rise and then evolves to fast-rise phase. We analyze using flux-rope insertion method magnetofrictional relaxation establish sequence plausible...

OBJECTIVES Amoxicillin use has been reported to be associated with developmental defects on enamel surfaces. This analysis assessed the association between amoxicillin use and fluorosis on late-erupting permanent teeth. METHODS As part of the Iowa Fluoride Study, subjects were followed from birth to 32 months with questionnaires every 3-4 months to gather information on fluoride intake and am...

Alveolar bone supports teeth during chewing through a ligamentous interface with tooth roots. Although tooth loads are presumed to direct the development and adaptation of these tissues, strain distribution in the alveolar bone at different stages of tooth eruption and periodontal development is unknown. This study investigates the biomechanical effects of tooth loading on developing alveolar b...
