From Nominalisation to Passive in Old Tibetan: Reconstructing Grammatical Meaning in an Extinct Language1

Transactions of the Philological Society, EarlyView.
Abstract Based on an analysis of the Old Literary Tibetan corpus—a corpus of the oldest documented Tibetic language—the present study provides evidence that literary Tibetan v3 verb stems (commonly termed ‘future’) initially encoded passive voice. New arguments put forward in this article range from Trans‐Himalayan nominal morphology to early Tibetan ...

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

Australian 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

Australian 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 ...

Biomechanical Analysis of 3D Printed and Thermoformed EVA Custom‐Made Mouthguard: Experimental and Finite Element Analyses

Dental Traumatology, EarlyView.
ABSTRACT Background/Objective 3D printed materials have been evaluated for fabricating mouthguards; however, little is known about their biomechanical performance in preventing dental trauma. This study aimed to compare two 3D printed polymers and three ethylene vinyl acetate (EVA) sheets used for mouthguard fabrication regarding their mechanical ...

Comfort and Usability of Digital Versus Conventional Custom‐Fit Mouthguards: A Randomized Clinical Trial

Dental Traumatology, EarlyView.
ABSTRACT Background/Objectives The use of mouthguards protects teeth and the supporting tissues against impacts. Digital impressions and 3D‐printed models can reduce manufacturing steps and minimize discomfort. This study evaluated the fit, comfort, and usability of custom‐made mouthguards, obtained by conventional and digital workflow, in amateur ...
