Pulp necrosis is an uncommon sequel to extrusive luxation in immature teeth with incomplete apical closure. In this report, we describe the management of severely extruded immature maxillary incisors and the outcome of revascularization to treat subsequent pulp necrosis. An 8.5-year-old boy with severe dentoalveolar trauma to the anterior maxillary region as a result of a fall was provided emer...

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...

Root fracture injuries affect up to 7% of permanent teeth. This type of injury is rarely seen in teeth with open apices and depending on the fracture site, the prognosis is good. This case report describes a horizontal intra-alveolar root fracture in the middle third of a maxillary central incisor associated with an extrusive luxation of the coronal segment and its treatment in a 6-year-old gir...

 Igneous Rocks form from the solidification of molten rock. Intrusive igneous rocks are composed of crystals that are large enough to be seen with the naked eye because these rocks cooled slowly, deep within the Earth thereby allowing time for the crystals to grow. In contrast, extrusive (volcanic) igneous rocks cool very quickly after they erupt from a volcano, and so are composed of microsco...

Helicobacter pylori (H.pylori) is a widely distributed human pathogen with high prevalence in human population. Many researches showed H.pylori infection is closely related with chronic gastritis, ganstric duodenal ulcer, mucosa associated diseases such as lymphoma and gastric cancer [1,2]. It has been classified as the class I carcinogen in 1994 by the World Health Organization and the Interna...
