introduction: failure of teeth to erupt from gingival tissues at usual developmental time is called delayed tooth eruption (dte). delayed tooth eruption lead to prolonged fixed orthodontic treatment and its eventual complications. the purpose of the present study was to evaluate the effect of laser-assisted (808 nm) surgical uncovering, on the tooth emergence and orthodontic treatment of dte. m...

third molar eruption is an unpredictable event. occasionally, mandibular third molars undergo angular changes in young adults. this rotational drift is of unknown etiology, is not predictable and may facilitate the eruption or may make the impaction worse. a rare case is presented with severe rotational drift of a mesioangularly impacted mandibular third molar.

Background: Pregnancy-specific dermatoses represent a group of pruritic skin diseases unique to pregnancy and the most common types are polymorphic eruption of pregnancy and pemphigoid gestationis. It is difficult to obtain a histopathological diagnosis for polymorphic eruption of pregnancy and pemphigoid gestationis in the lack of immunofluorescence because of their similar clinical presentati...

Background: Skin eruption is a disease that it is because of skin necrosis and adolescence and youth depression. The some species of Staphylococcuss are agent of this disease. There isn’t effective drug for curing of this disease. Many of medicinal plants (e.x. Stachys inflata Benth.) have anti- bacterial compounds and they can be used as a drug to cure skin eruption disease. Objective: This r...

BACKGROUND Tooth eruption is a continuous biological process by which developing teeth emerge through the jaws and the overlying mucosa to enter into the oral cavity. Tooth eruption time and sequence are important factors in dental treatment planning, particularly in orthodontics, but also in forensic dentistry to estimate age of a child. Tooth eruption time is influenced by many factors. In th...

[1] A hydrovolcanic eruption near Cone D on the floor of Okmok caldera, Alaska, began on 12 July 2008 and continued until late August 2008. The eruption was preceded by inflation of a magma reservoir located beneath the center of the caldera and ∼3 km below sea level (bsl), which began immediately after Okmok’s previous eruption in 1997. In this paper we use data from several radar satellites a...

Tooth eruption is a localized process in the jaws which exhibits precise timing and bilateral symmetry. It involves resorption and formation of bone on opposite sides of the erupting tooth and these activities depend on the dental follicle, a thin connective tissue investment of the developing and erupting tooth, Biochemical studies have shown that during eruption cells, proteins and enzymes ch...

We report a case of fixed drug eruption caused by fluconazole. A local provocation with 10% fluconazole test in petrolatum applied at the site of a previous lesion of fixed drug eruption reproduced the eruption clinically and histopathologically.

Background: Serious cutaneous eruptions caused by cytarabine are never reported in China. Methods: We admitted a 43-year-old man who was diagnosed with acute non-lymphocytic leukemia, and was given several chemotherapy regimens including cytarabine. And when FLAG regimens were given in the patient, the serious pustular eruption appeared. Results: After the treatment, cutaneous eruption was grad...

Eruption disorders are numerous varying from delayed to complete failure of eruption. Primary failure of eruption (PFE) is a rare condition that involves arrested eruption of teeth with the absence of local or general contributory factors. Another rare and clinically challenging phenomenon is canine transmigration which is the intra-osseous movement of impacted canines across the midline. This ...
