background: to determine the mean eruption time of permanent teeth of pakistani children and to evaluate the effects of gender, type of schools, height, weight and body mass index on it. methods: this cross sectional study was conducted from september 2007 to april 2008.  4370 children of ‘just erupted' teeth were obtained from 102 randomly selected schools from 18 towns of karachi, using syste...

Eruption hematoma is a macular elevation in the soft tissue of alveolar mucosa seen nearly during the tooth eruption. Commonly, it does not have any clinical symptoms. In most cases, the black dome shape appearance of eruption hematoma worries parents about malignancy. Since the physicians are often the firsts who examine the affected child, this lett...

introduction: complicated crown- root fractures, extended caries and iatrogenic destruction often result in insufficient sound tooth structures and compromise the biologic width. two common options for re-establishing flap with osseous surgery. although some advantages are related to these two options, but coronal movement of gingival and alveolar bone in orthodontic extrusion, esthetic problem...

Abstract The violent disruption of the coronal magnetic field is often observed to be restricted low corona, appearing as a confined eruption. possible causes confinement remain elusive. Here, we model eruption flux rope in quadrupolar active region, with parameters set such that X-lines exist both below and above rope. This facilitates onset reconnection either place but partly opposing effect...

Human eruption is a unique developmental process in the organism. The aetiology or the mechanism behind eruption has never been fully understood and the scientific literature in the field is extremely sparse. Human and animal tissues provide different possibilities for eruption analyses, briefly discussed in the introduction. Human studies, mainly clinical and radiological, have focused on norm...

we describe, the first case of phenobarbital-induced dress syndrome presenting as a lichenoïd eruption. a 49-year-old man had received phenobarbital for a cerebral metastasis. twenty-five days later, he developed a purplish skin eruption, odynophagia, oral mucosal erosion and fever. physical examination revealed a cervical lymphadenopathy and facial edema associated to a diffuse violaceous macu...

Abstract We analyze the formation mechanism of three homologous broad coronal mass ejections (CMEs) resulting from a series solar blowout-eruption flares with successively increasing intensities (M2.0, M2.6, and X1.0). The originated NOAA Active Region 12017 during 2014 March 28–29 within an interval ≈24 hr. Coronal magnetic field modeling based on nonlinear force-free extrapolation helps to id...

Decoronation of ankylosed teeth in infraposition was introduced in 1984 by Malmgren and co-workers (1). This method is used all over the world today. It has been clinically shown that the procedure preserves the alveolar width and rebuilds lost vertical bone of the alveolar ridge in growing individuals. The biological explanation is that the decoronated root serves as a matrix for new bone deve...

The rotational motion of solar jets is believed to be a signature of the untwisting process resulting from magnetic reconnection, which takes place between twisted closed magnetic loops (i.e., magnetic flux ropes) and open magnetic field lines. The identification of the pre-existing flux rope, and the relationship between the twist contained in the rope and the number of turns the jet experienc...
