Shear Bond Strength Comparison between Two Orthodontic Adhesives and Self-Ligating and Conventional Brackets [PDF]

open access: yes, 2007
Objective: To evaluate and compare the shear bond strengths of two adhesives using two types of brackets: a conventional and a self-ligating bracket system. Materials and Methods: Sixty extracted human premolars were collected.

Variation in parrot jaw musculature

open access: yesThe Anatomical Record, EarlyView.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

Normal and altered masticatory load impact on the range of craniofacial shape variation: An analysis of pre-Hispanic and modern populations of the American Southern Cone.

open access: yesPLoS ONE, 2019
The reduction of masticatory load intensity resulting from dietary changes in human evolution has been proposed as an important factor that alters craniofacial shape in past and current populations.

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 ...

Study of masticatory forces of complete denture wearers.

open access: yesTHE JOURNAL OF THE STOMATOLOGICAL SOCIETY,JAPAN, 1990
Bilateral balanced occlusion is believed to be one of the ideal types of occlusion for complete denture. However, there are still many obscure items about its function during mastication, considering that the occlusion is adjusted on the articulators under the no-food condition.

Maximum Bite Force Analysis in Different Age Groups [PDF]

open access: yes, 2014
Introduction Maximum bite force (MBF) is the maximum force performed by the subject on the fragmentation of food, directly related with the mastication and determined by many factors. Objective Analyze the MBF of subjects according to age groups. Methods

Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

open access: yesThe Anatomical Record, EarlyView.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Quantitative Comparison of Age‐Related Development of Oral Functions During Growing Age

open access: yesClinical and Experimental Dental Research
Objectives This cross‐sectional study aimed to investigate the age‐related development of five major oral functions—tongue pressure, lip pressure, masticatory efficiency, bite force, and occlusal contact area—in subjects aged 5–20 years.
