Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

The Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology

Biological Reviews, EarlyView.
ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.

A Core Head, Neck, and Neuroanatomy Syllabus for Physical Therapy Student Education

Clinical Anatomy, EarlyView.
ABSTRACT Head, neck, and neuroanatomy are essential components of physical therapy education due to their broad clinical applications. Detailed syllabi exist for medical students, yet none have been developed for physical therapy. This study aimed to produce an International Federation of Associations of Anatomists core head, neck, and neuroanatomy ...

C-shaped root canal systems in the bilateral mandibular first molars: a case report and literature review

BMC Oral Health
Background Mandibular first molars typically exhibit complex root and canal anatomy. A thorough understanding of their morphological variations is crucial for endodontists to achieve successful root canal treatment.

Root canal morphology of permanent mandibular incisors of Saudi subpopulation in Al-Baha region: A cone-beam computed tomography study

Saudi Endodontic Journal
Introduction: A proper understanding of root canal morphology and its deviations is essential for improving the outcomes of endodontic procedures. Therefore, the current study aims to explore the root canal morphology of permanent mandibular central and ...

Preservation therapy for vertically fractured teeth with periodontal tissue regeneration using FGF‐2

Clinical Advances in Periodontics, EarlyView.
Abstract Background Vertically fractured teeth often have a poor prognosis, and extraction is considered the most predictable treatment. Conventional management has consisted of preservation therapy involving extraction, bonding, root restoration, and replantation of fractured teeth.

Cone-beam computed tomography study of root and canal morphology of mandibular premolars in a western Chinese population

BMC Medical Imaging, 2012
Background Traditional radiography is limited in its ability to give reliable information on the number and morphology of root canals. The application of cone-beam computed tomography (CBCT) provides a non-invasive three-dimensional confirmatory ...

A rare mental foramen variation and the role of cone‐beam computed tomography in preventing nerve injury: A case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background The interforaminal space is frequently used for dental implant placement due to its strategic location between the bilateral mental foramina. However, neurosensory disturbances following surgical intervention near the mental foramen (MF) can occur in up to 43% of cases.
