Orthodontic management of uneven gingival margins in patients with healthy or reduced periodontium to improve smile aesthetics

Periodontology 2000, EarlyView.
Abstract Uneven gingival margins may cause visible asymmetries during smiling and may reflect alterations in the tooth shape and morphology, particularly in cases requiring restorative procedures. Despite being perceived as a minor health condition, presence of uneven gingival margins usually impacts the smile aesthetics and could affect the individual'

Pathologic Characterization and Clinical Significance of Lymphovascular Invasion in Canine Thyroid Carcinomas

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT The association between lymphovascular invasion (LVI) and outcomes in dogs with thyroid carcinoma is inadequately described, and a standardized definition of LVI is lacking. This study's objectives were to histopathologically and immunohistochemically characterize LVI and to evaluate associated clinical outcomes in dogs with thyroid carcinoma.

Medial Tympanic Membrane Displacement in Five Dogs Resembling Tympanic Membrane Retraction in Humans

Veterinary Dermatology, EarlyView.
Five dogs with head tilt, ataxia, incoordination or deafness without a history of otitis externa (OE) were diagnosed with otitis media by computed tomography (CT) or magnetic resonance imaging (MRI). Otoendoscopy showed possible tympanic membrane retraction with opaque, fibrotic membranes and advanced imaging showed middle ear involvement. The clinical
