CONTEXT Symptoms associated with the primary tooth eruption have been extensively studied but it is still controversial. OBJECTIVE To assess the occurrence of local and systemic signs and symptoms during primary tooth eruption. DATA SOURCES Latin American and Caribbean Health Sciences, PubMed, ProQuest, Scopus, and Web of Science were searched. A partial gray literature search was taken by ...

This study evaluated the superficial microhardness of enamel in teeth at different posteruptive ages (before eruption in the oral cavity, 2-3 years after eruption, 4-10 years after eruption and more than 10 years after eruption). The study sample was composed of 134 specimens of human enamel. One fragment of each tooth was obtained from the flattest central portion of the crown to produce speci...

[1] Climate records indicate that the decade of AD 1810–1819 including ‘‘the year without a summer’’ (1816) is probably the coldest during the past 500 years or longer, and the cause of the climatic extreme has been attributed primarily to the 1815 cataclysmic Tambora eruption in Indonesia. But the cold temperatures in the early part of the decade and the timing of the Tambora eruption call int...

abstract fixed drug eruption (fde) is a unique type of cutaneous drug reaction that typically recurs in the identical locations on re-exposure to the attributed drug. fde is characterized by the appearance of a single or multiple sharply demarcated violaceous erythematous plaques which heal with residual hyperpigmentation. a 27-year-old woman presented with multiple dark patches over her eyelid...

a-10-year-old girl was referred to our department for multiple hyperpigmented plaques. one  week  previously,  she  had  been  given  one  suppository  of  acetylsalicylic acid  – phenobarbital for fever. twelve hours after the drug intake the child developed pruritic red plaques on the left thigh. six weeks after resolution of the acute reaction, patch tests were performed separately, with phe...

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...

A significant body of research evidence (70+ studies) available since the 1940s (Short et al. 1944) suggests that fluoride delays the eruption of teeth, thereby merely delaying the development of cavities. This delay has been reported to be anywhere from several months (Tseng et al, 1989) to 2 years (Campagna et al, 1995). This delay in the onset of caries due to a delay in eruption of teeth wi...

Previous studies have suggested methods for predicting third molar tooth eruption radiographically. Still, this prediction is associated with uncertainty. The aim of the present study was to elucidate the association between cephalometric measurements on profile and panoramic radiographs and to find a simple and reliable method for predicting the eruption of the mandibular third molar by measur...

BACKGROUND Piroxicam is a widely used anti-inflammatory drug. Most adverse reactions affect gastrointestinal system, liver and skin. Fixed drug eruption although very unusual, has also been described, but with cutaneous involvement exclusively. We present the case of a 49-year-old man who suffered three episodes of fixed drug eruption with cutaneous-mucosal involvement, even simulating an autoi...

Drug eruption is the most common clinical presentation in patients with HIV/AIDS. The systemic clinical and risk factors associated with drug eruption remain unknown. A retrospective analysis in HIV/AIDS patients with drug eruption was carried out with demographic data, epidemiological data, clinical characteristics, laboratory data and follow-up data. The risk factors correlated with prognosis...
