Delayed tooth eruption (DTE) is the emergence of a tooth into the oral cavity at a time that deviates significantly from norms established for different races, ethnicities, and sexes. This article reviews the local and systemic conditions under which DTE has been reported to occur. The terminology related to disturbances in tooth eruption is also reviewed and clarified. A diagnostic algorithm i...

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 ...

Eruption pattern of permanent teeth in Delhi boys was studied in 1800 well nourished children age 5-14 years. Relationship of height, weight and sexual maturity with eruption of teeth was calculated. Earliest teeth to appear were lower first molar (5.64 years) followed by lower central incisors (6.02 years), The sequence of eruption in maxilla was first molar, incisors-central then lateral, fir...

This article reviews the infrequently utilized treatment method of forced eruption and how it can serve as an alternative to the sacrifice of the natural root system. Forced eruption can preserve the natural root system and related periodontal architecture, resulting in years of additional service for the patient. It also can maintain adjacent tooth structure while retaining the option for futu...

The sensational 1980 eruption ofMount St.Helens and the subsequent ecological responses are the most thoroughly studied volcanic eruption in theworld. The posteruption landscapewas remarkable, and nearly a quarter century of study has provided awealth of information and insight on a broad spectrum of ecological and physical responses to disturbance. The eruption and its effects on ecological an...

Kaposi’s varicelliform eruption (KVE) is a typeof skin disorder caused mainly byherpes simplex virus (HSV) type 1 and2 and occasionally by coxsackie A 16 and vacciniavirus, which is commonly found in the second andthird decades of life. It is predominantly associatedwith atopic dermatoses. Therefore, it is also termedeczema herpeticum (EH) 1. Herein, we report acase of Kaposi’s varicelliform er...

The Late Pleistocene Campanian Ignimbrite (CI) super-eruption (Southern Italy) is the largest known volcanic event in the Mediterranean area. The CI tephra is widely dispersed through western Eurasia and occurs in close stratigraphic association with significant palaeoclimatic and Palaeolithic cultural events. Here we present new high-precision 14C (34.29 ± 0.09 14C kyr BP, 1σ) and 40Ar/39Ar (3...
