Root and Canal Morphology of Maxillary Premolars in a Namibian Population: A Retrospective Cone‐Beam Computed Tomography Study

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This study examined population‐specific morphological variations in human premolar roots and canals and their clinical implications. Cone‐beam computed tomography (CBCT) was used with the Ahmed classification system. A retrospective descriptive cross‐sectional study analysed 388 maxillary premolars from CBCT scans of 97 participants obtained ...

Is Cone‐Beam CT Reliable for Apical Foramen Assessment? A Micro‐CT–Referenced Study

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the diagnostic accuracy of two cone‐beam CT (CBCT) dose protocols for identifying the number and trajectory deviation of apical foramina. Forty lower molars were scanned in Micro‐CT. Thereafter, all teeth were inserted into the mandible sockets and a titanium implant and an endodontically treated tooth with a cobalt ...

Discuss the Rationale for Minimally Invasive Endodontics and the Merits and Demerits of the Concept

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT Minimally invasive endodontics (MIE) places emphasis on the conservation of sound tooth structure and viable pulp tissue during endodontic procedures such as root canal treatment (RCTx) and vital pulp therapy (VPT). The use of minimal access cavity designs and conservative canal preparation dimensions have been investigated as a way to improve

MYLK c.4079G>A, p.(Gly1360Asp) Variant Associated With Hereditary Thoracic Aortic Diseases and Early Onset Aortic Dissection

open access: yesAnnals of Human Genetics, EarlyView.
ABSTRACT Aims Thoracic aortic aneurysms and dissections are major causes of sudden cardiovascular death. We aimed to evaluate the clinical significance of the MYLK c.4079G>A, p.(Gly1360Asp) variant in Finnish families with heritable thoracic aortic disease (HTAD) and to assess evidence for a potential founder effect.

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions

open access: yesArchaeometry, EarlyView.
ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

Direct Evidence of the Geographic Origins of Horse in the Yaoheyuan Site From Ningxia, China

open access: yesArchaeometry, EarlyView.
ABSTRACT In this study, It is explores the geographic origin of horses by analyzing the strontium isotope ratio of horses from the Yaoheyuan site, an important site in the northwest region of China during the Western Zhou Dynasty. The results show that most of the horses at the Yaoheyuan site were domesticated locally, while a small number came from ...
