Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

New fossil unveils the dentary anatomy of the rare lepidosauromorph Cargninia enigmatica from the Upper Triassic of Southern Brazil

The Anatomical Record, EarlyView.
Abstract Nowadays, Lepidosauria is a diverse group represented by squamates and the rhynchocephalian tuatara. However, their origins date back to the end of the Permian Period, when the stem lineages Lepidosauromorpha and Archosauromorpha diverged. Within the lepidosauromorph stem lineage, a few species have been described with unstable phylogenetic ...

External Acoustic Meatus Approach for Ultrasonographic Evaluation of the Temporomandibular Joint: An Anatomical Validation and Proof‐of‐Concept Study

Clinical Anatomy, EarlyView.
ABSTRACT Temporomandibular disorders (TMD) represent a public health problem, affecting 31% of adults and the elderly and 11% of children and adolescents. Interest is growing in using ultrasound to evaluate the temporomandibular joint (TMJ). However, researchers need to standardize a reliable method.

Management of severe bone loss in patients at risk of medication‐related osteonecrosis of the jaw with microsurgery and guided bone regeneration: A case study

Clinical Advances in Periodontics, EarlyView.
Abstract Background Medication‐related osteonecrosis of the jaw (MRONJ) is a challenging complication associated with antiresorptive medications. Its exact pathophysiology remains unclear, but dental extractions and infections are known triggers, complicating prevention, and treatment.

Endodontic Retreatment Of Mandibular Incisors With Root Canals Variations

International Dental Journal
Introduction: Mandibular incisors have been found to have a complex anatomy of the root canal system. Missed root canals are the most likely cause of treatment failure, and the persistent intra-radicular infections can lead to periapical lesion and ...

Modified Neumann incision for implant placement in overdentures: Case series of a less invasive alternative

Clinical Advances in Periodontics, EarlyView.
Abstract Background Conventional envelope flap techniques for implant placement in edentulous mandibles are associated with greater postoperative morbidity, especially in elderly patients or those with anatomical limitations. Minimally invasive alternatives aim to preserve soft tissues and reduce complications, enhancing clinical predictability ...
