Dens Invaginatus as a Biomechanical Risk Modifier in Dental Trauma: Finite Element Analysis

open access: yesDental Traumatology, EarlyView.
ABSTRACT Introduction/Aims Traumatic dental injuries are common in childhood and may adversely affect functional and psychosocial well‐being. Dens invaginatus, a developmental anomaly caused by the infolding of the enamel organ during odontogenesis, alters tooth morphology and may influence biomechanical behavior under traumatic loading.

High prevalence of loss of Claudin‐18 expression in invasive non‐mucinous lung adenocarcinoma: Potential diagnostic implications in routine practice

open access: yesHistopathology, EarlyView.
Loss of Claudin‐18 (Cldn18) expression is a frequent and specific feature of non‐mucinous lung adenocarcinoma (NM‐LUAD). Cldn18 immunohistochemistry may serve as an ancillary tool for distinguishing malignant from non‐neoplastic alveolar epithelium, as well as for differentiating NM‐LUADs with mucin production from M‐LUADs, particularly in small or ...

A re‐usable 3D‐printed training model for the endodontic management of dental trauma in immature teeth

open access: yesInternational Endodontic Journal, EarlyView.
Abstract Aim To develop a 3D‐printed model enabling treatment simulation of trauma‐related endodontic and restorative procedures like revitalization or placement of an apical plug on teeth with incomplete root formation. Methodology To generate a realistic training model suitable for trauma‐related simulations, CT‐Data sets were segmented, combined ...
