“Visiting scientist effect”? Exploring the impact of time‐lags in the digitization of 2D landmark data

open access: yesThe Anatomical Record, EarlyView.
Abstract Measurement error (ME) in geometric morphometrics has been the subject of countless articles, but none specific to the effect of time lags on landmark digitization error. Yet, especially for visiting scientists working on museum collections, it is not uncommon to collect data in multiple rounds, with interruptions of weeks or years. To explore

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

open access: yesThe Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

Osteochondroma involving mandibular condyle

open access: yesJournal of Indian Academy of Oral Medicine and Radiology, 2017
Osteochondroma is defined as an osteocartilagenous exostosis with cartilage capped exophytic lesion that arises from the bone cortex. It is a slow growing benign tumor that is rarely seen in the maxillofacial region.

Computer Aided Detection of Oral Lesions on CT Images [PDF]

open access: yes, 2016
Oral lesions are important findings on computed tomography (CT) images. In this study, a fully automatic method to detect oral lesions in mandibular region from dental CT images is proposed. Two methods were developed to recognize two types of lesions namely (1) Close border (CB) lesions and (2) Open border (OB) lesions, which cover most of the lesion ...

Silesaurid (Archosauria: Dinosauriformes) remains from the base of the Dockum Group (Late Triassic: Otischalkian) of Texas provide new insights to the North American record of dinosauriforms

open access: yesThe Anatomical Record, EarlyView.
Abstract Silesaurids (Archosauria: Dinosauriformes) are found in Middle to Upper Triassic deposits across Pangea, but few stratigraphic sections record the evolution of the group in one geographic area over millions of years. Here, we describe silesaurid remains from the oldest of the Upper Triassic stratigraphic sequence from the base of the Dockum ...

Bilateral bifid mandibular condyle: Report of a case with condylar fractures

open access: yesJournal of Oral and Maxillofacial Radiology, 2013
Bifid mandibular condyle is an uncommon anatomic variation with a varied etiology implicated with its development. It can be symptomatic or the majority of the cases are diagnosed incidentally during radiographic examination. Bifid mandibular condyle may

The relationship between form and function of the carnivore mandible

open access: yesThe Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Shaping the human face: Periosteal bone modeling across ontogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Facial morphology is a defining aspect of Homo sapiens that distinguishes our species from fossil ancestors and plays a central role in estimating age, sex, and ancestry in both past and present populations. Understanding how the face develops during postnatal ontogeny is essential for interpreting adult facial variation.

Condyle dislocation following mandibular reconstruction using a fibula free flap: complication cases

open access: yesMaxillofacial plastic and reconstructive surgery, 2019
Condylar dislocation can arise as a complication in patients who required mandibular and/or condylar reconstruction and were operated on with fibula free flap (FFF) using surgical guides designed using simulation surgery.
