Accommodation of Dental Variations During Jaw Growth in Ungulate Mammals

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Using geometric morphometrics, we compared the covariation pattern of the dentition and the palate during growth in 23 ungulate species. ABSTRACT The growth of teeth and jaw bones is intimately linked in vertebrates, especially in mammals due to their specialized dentition and limited body growth.

Management of Impacted Premolar With Root Dilaceration Caused by Radicular Cyst in Deciduous Molar: A Case Report

open access: yesCase Reports in Dentistry
Radicular cyst is the most common inflammatory odontogenic cyst in the oral cavity, but it rarely occurs in deciduous teeth. Radicular cysts in deciduous teeth can lead to root dilaceration in permanent successor teeth, resulting in impacted permanent ...

Angelica danxiacola (Apiaceae), a new species from eastern China based on morphological and molecular data

open access: yesNordic Journal of Botany, EarlyView.
Angelica danxiacola, a new species of Apiaceae from Danxia landform in Zhejiang Province, eastern China, is described and illustrated. This species exhibits similarities in morphological features to A. morii but is distinguishable by several discrete features, such as the shape and size of the leaf blades and leaflets, number of rays, pedicel length ...

Maternal and Gestational Influences on Deciduous and Permanent Tooth Size [PDF]

open access: yesJournal of Dental Research, 1980
Although there have been suggestions that prenatal factors could affect crown dimensions (Bailit and Sung, Archs Oral Biol 13:155-166, 1968; Cohen, Baum, Garn, Osario and Nagy, in: Orofacial Growth and Development, Dahlberg and Graber, eds., Mouton Publishers, The Hague, 1977, pp 119-126), limitations of sample size and investigative design restrict ...

Phylogeny and historical biogeography of the Pachira sensu lato clade (Bombacoideae, Malvaceae) with a new infrageneric classification

open access: yesTAXON, EarlyView.
Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species

Sexual dimorphism in the tooth‐crown diameters of the deciduous teeth [PDF]

open access: yesAmerican Journal of Physical Anthropology, 1978
AbstractMesiodistal and buccolingual crown dimensions of the right deciduous teeth of 133 white children were analyzed for information on sexual dimorphism and sex discrimination using discriminant analysis. Even though consistent differences were found for only 15 out of 20 paired measurements, five of them significant at p = 0.05 or better ...

Living under the scope: behavior affects survival in a heavily harvested and long‐lived ungulate

open access: yesWildlife Biology, EarlyView.
The spatiotemporal behavior of game species may play a critical role in their survival throughout the hunting season. Where humans are the most dominant predators, avoidance of landscape features that allow hunter access to hunting grounds can be key to increasing survival.

Delayed eruption of permanent dentition and maxillary contraction in patients with cleidocranial dysplasia: review and report of a family [PDF]

open access: yes, 2018
Introduction. Cleidocranial dysplasia (CCD) is an inherited disease caused by mutations in the RUNX2 gene on chromosome 6p21. This pathology, autosomal dominant or caused by a spontaneous genetic mutation, is present in one in one million individuals ...
