First evidence of a mandibular crest in Brasileodactylus Kellner, 1984 (Pterosauria, Pteranodontoidea, Anhangueridae), with comments on pterosaur headcrests

The Anatomical Record, EarlyView.
Abstract Brasileodactylus araripensis Kellner, 1984, is a toothed pterosaur from the Lower Cretaceous Romualdo Formation of the Araripe Basin, Brazil. Traditionally regarded as crestless, the species has been central to debates on anhanguerid taxonomy, as most members of the clade possess well‐developed sagittal cranial or dentary crests.

Regional Histological Anatomy of the Supraperiosteal Tissues of the Oral Cavity: Implications for Periodontal Flap Surgery and Periosteal Releasing Incisions

Clinical Anatomy, EarlyView.
ABSTRACT Periodontal and implant procedures increasingly involve tissue planes superficial to the periosteum, yet their regional anatomy remains poorly understood. This study conducted a histological investigation of the supraperiosteal anatomy of the oral cavity and its implications for periosteal releasing incisions (PRIs).

Subperiosteal peri‐implant augmented layer to correct bone dehiscence at immediate implant placement

Clinical Advances in Periodontics, EarlyView.
Abstract Background The purpose of the present case report is to describe the potential of the subperiosteal peri‐implant augmented layer (SPAL) technique in peri‐implant bone dehiscence (PIBD) correction at immediate implant placement (IIP). Methods This case report describes the application of the SPAL technique in two patients undergoing IIP at ...

Combining the tunneled coronally advanced flap (TCAF) with internal frenectomy–vestibular incision subperiosteal tunnel access (IF‐VISTA) for the treatment of mandibular anterior gingival recessions: A technique report

Clinical Advances in Periodontics, EarlyView.
Abstract Introduction Gingival recession (GR) defects in the mandibular anterior region represent a particularly challenging scenario in periodontal plastic surgery, owing to a thin soft tissue phenotype, minimal keratinized tissue, limited vestibular depth, and the frequent presence of a prominent labial frenum.

Stereotactic Body Radiation Therapy for Head and Neck Cancers With Perineural Spread

Head &Neck, EarlyView.
ABSTRACT Background Perineural spread (PNS) in head and neck cancer (HNC) is technically challenging due to complex target volumes adjacent to critical organs. Data on stereotactic body radiation therapy (SBRT) for PNS is scarce. Methods This retrospective study included patients treated with SBRT for PNS across two centers in the USA and Canada from ...

Mapping the Landscape of Over‐Scanning in CT Imaging: A Scoping Review

Journal of Medical Radiation Sciences, EarlyView.
Over‐scanning in CT is highly prevalent and contributes to unnecessary radiation exposure, with notable impact on radiosensitive organs. Standardised protocols and AI‐assisted planning show strong potential to optimise scan range and reduce excess dose.
