INTRODUCTION Posterior open bite has several possible causes, including primary failure of eruption (PFE) that affects all teeth distal to the most mesial involved tooth, mechanical failure of eruption (MFE) (primarily ankylosis) that affects only the involved tooth or teeth, and soft-tissue interferences with eruption (other). METHODS Radiographs and other clinical records for 97 cases of fa...

Okmok, a ~10-km wide caldera that occupies most of the northeastern end of Umnak Island, is one of the most active volcanoes in the Aleutian arc. The most recent eruption at Okmok during July–August 2008 was by far its largest and most explosive since at least the early 19th century. We investigate post-eruptive magma supply and storage at the volcano during 2008–2014 by analyzing all available...

background: odontomas are among the most common benign odontogenic tumors, which are mostly discovered in the first and second decades of life with no clear sex predilection. materials and methods: the present retrospective study reviews the clinical, radiological, and the histopathological characteristics of odontomas in 19 libyan patients seen during the last 18 years in our department. resul...

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 In this prospective longitudinal study, we compared the prevalence of mandibular second molar eruption difficulties in patients treated with appliances to maintain mandibular arch perimeter. Other independent variables (age, molar angulation, space-width ratio, treatment time, and sex) were tested for their value as predictors of eruption difficulty. METHODS Three hundred one pat...

Abnormalities of dental development and eruption occur quite commonly in the horse and result in a wide range of clinical conditions. A congenital/developmental problem present at the time of tooth eruption often leads to acquired dental problems as the teeth continue to erupt and wear. Consequently, several different dental abnormalities whose pathogenesis may be inter-related, are often prese...

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...

Aims. We report observation of a large-amplitude filament oscillation followed by an eruption. This is used to probe the pre-eruption condition and the trigger mechanism of solar eruptions. Methods. We used the EUV images from the Extreme-Ultraviolet Imaging Telescope on board SOHO satellite and the Hα images from the Flare Monitoring Telescope at Hida Observatory. The observed event is a polar...
