background and aims. the objectives of the present study were to investigate the prevalence and the position of enamel defects of primary teeth and hence to estimate the approximate time of an insult. material and methods. 121 children aged 3 to 5 years were included in the study. the modified developmental defects of enamel index was used to diagnose and classify the defects. the defects were ...

Multiple impacted teeth are a rare eruption disturbance that increases the case complexity. In this article, we described a 13-year-old boy whose 5 permanent maxillary teeth were not erupted although their root formation was complete. The orthodontic treatment with traction and asymmetric extraction was performed to achieve a significantly improved functional and esthetic result.

Fossils of a predatory dinosaur provide novel information about the evolution of unenlagiines, a poorly known group of dromaeosaurid theropods from Gondwana. The new dinosaur is the largest dromaeosaurid yet discovered in the Southern Hemisphere and depicts bizarre cranial and postcranial features. Its long and low snout bears numerous, small-sized conical teeth, a condition resembling spinosau...

1,3-Diphenylbenzo[e][1,2,4]triazin-7(1H)-one, the oxidation product of 1,3-diphenyl-1,4-dihydro-1,2,4-benzotriazin-4-yl (Blatter's radical), reacts with N'-arylbenzamidines in PhMe at ca. 100 °C in the presence of N,N-diisopropylethylamine (Hünig's base) (1 equiv.) to give N'-aryl-N-(1,7-dihydro-7-oxo-1,3-diphenylbenzo[e][1,2,4]triazin-6-yl)benzimidamides in 49-95% yield. In neat AcOH heated at...

background: hypoglycemia is one of the most common neonatal disorders, associated with severe complications. there has been a great deal of controversy regarding the definition and screening of hypoglycemia. therefore, in this study, we aimed to determine a cut-off value for blood glucose level in glucometer readings. methods: this cross-sectional study was conducted on 238 newborns at risk of ...

Hypohidrotic ectodermal dysplasia (HED) is a syndrome characterized by hypodontia, hypotrichosis, and partial or total ecrine sweat gland deficiency. The most prevalent form of HED is inherited as an X linked pattern. Glucose-6-phosphate dehydrogenase (G-6-PD) deficiency is an X-linked recessive disease, which leads to hemolytic anemia and jaundice. It is expressed in males, while heterozygous ...

In this study, the expression of proteolipid protein (PLP) and nestin is studied in the late bell stage of developing rodent teeth in neonatal rats. By using immunohistochemistry, it was shown that odontoblasts, ameloblasts and the stratum intermedium are positive for PLP in regions of active matrix deposition. Reactivity for nestin could be detected in the odontoblasts, stratum intermedium and...
