Odontomas are the most common type of odontogenic tumors and account for approximately 22% of maxillary odontogenic tumors [1-3]. They are considered to be developmental anomalies rather than true neoplasms [4]. They are generally asymptomatic [1]. The term odontoma was coined by Paul Broca in 1867. The World Health Organization (WHO) 2005 has categorized odontomas based on the histopathologica...

A new species of the alvinocaridid shrimp genus Alvinocaris Williams & Chace, 1982 is described from the Solitaire hydrothermal vent field at 2606 m depth on the Central Indian Ridge. Alvinocaris solitaire sp. nov., the first species of the genus to be recorded from the Indian Ocean, is morphologically most similar to A. lusca Williams & Chace, 1982 from the Galapagos Rift, East Pacific Rise. T...

Familial severe hypodontia of the permanent dentition is a rare condition. The genetics of this entity remains unclear and several modes of inheritance have been suggested. We report here an increase in the number of congenitally missing teeth after the mating of affected subjects from two unrelated Norwegian families. This condition may be the result of allelic mutations at a single gene locus...

whether enough blood circulated in or around the plates to ensure such a function. Furthermore, while the large, flat plates of Stegosaurus might have been thermoregulatory, it is less easy to imagine this working in the spike-like osteoderms of Kentrosaurus. Another possibility is that the plates had a behavioural function, and were used in either sexual selection (there is no apparent sexual ...

BACKGROUND A maxillary midline diastema (MMD) often is a primary concern of patients during a dental consultation. Although an MMD can be transient owing to the developing dentition and, thus, requires no active treatment, management of MMDs in the permanent dentition requires a detailed examination and appropriate care. CASE DESCRIPTION . The authors present five cases of MMDs in adults to ...

BACKGROUND Researchers have conducted extensive studies regarding dentoalveolar factors that affect anterior dental esthetics; however, there is no consensus regarding laypeople's perspectives on these factors. METHODS The authors conducted a systematic search of electronic databases (MEDLINE, PubMed, Embase, Cochrane Library and Web of Science) until May 2010. They identified and selected ar...

While studying organisms living in association with the solitary tunicate Phallusia nigra (Ascidiacea, Ascidiidae) from a shallow fringing reef at Zeytouna Beach (Egyptian Red Sea), one of the collected ascidians showed peculiar perforations on its tunic. Once dissected, the perforations revealed to be the openings of a network of galleries excavated in the inner tunic (atrium) by at least six ...

BACKGROUND AND AIM: Dental anomalies are typically detected in radiographic screening. The present study was conducted with the aim of investigating the dental anomalies found in panoramic radiographs taken from the study population in Ardabil, Iran, in 2015-2016.METHODS: The present study was conducted on 1800 panoramic radiographs obtained from 799 men and 1001 women in the Radiology Departme...

The lack of a protuberance in the basal antennal article in the holotype of Pinnotheres orcutti Rathbun, 1918, allows its removal from Pinnotheres Bosc, 1802 [type species, P. pisumn (Linnaeus, 1767)]. The species is instead included in Tumidotheres Campos, 1989, because of the presence of a thick, tumid and firm carapace, and its surface covered with a short, dense, and deciduous tomentum; the...
