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 ...

Hydroxylapatite and tricalcium phosphate implants in the dental alveolus of rats. A histometric study.

open access: yesBrazilian dental journal, 1996
The objective of the present study was to analyze histomorphometrically the biological behavior of microgranular hydroxylapatite (HA 40), and tricalcium phosphate (TCP) implanted in the dental alveolus of rats. All three materials retarded alveolar repair when compared to controls, since less bone was formed during all periods of study.

Antibiotic‐Induced Dysbiosis of the Gut Microbiota Shifts Host Tryptophan Metabolism and Increases the Susceptibility of Mice to Pulmonary Infection With Pseudomonas aeruginosa

open access: yesImmunology, EarlyView.
Antibiotic‐induced dysbiosis of the gut microbiota shifts host tryptophan metabolism and impairs the innate immune response during Pseudomonas aeruginosa pulmonary infection. (A) Eubiosis: During eubiosis, the intestinal microbiota metabolises tryptophan into indole metabolites, which keeps tryptophan levels within normal serum concentrations. However,

The Landscape of SPP1+ Macrophages Across Tissues and Diseases: A Comprehensive Review

open access: yesImmunology, EarlyView.
SPP1+ macrophages represent a conserved, disease‐associated population present across cancerous and non‐cancerous conditions, involved in immunosuppression, fibrosis, lipid metabolism, phagocytosis, and other cellular processes. This review highlights their shared molecular programmes across tissues, their interactions with stromal and immune cells ...

Almost billfish: convergent longirostry, micro‐dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy

open access: yesJournal of Anatomy, EarlyView.
A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

Evaluation of maxillary transverse dimensions in individuals with a unilaterally impacted canine

open access: yesJournal of Orthodontic Science
INTRODUCTION: The aim of this study was to investigate the maxillary width within individuals with a unilaterally impacted maxillary canine and to determine any association between the impacted canine location and some canine-related variables.

How is the third jaw joint in whales different? Diverse modes of articulation between the jaws of whales

open access: yesJournal of Anatomy, EarlyView.
This study conducts the first comprehensive morphological investigation of the mandibular symphysis in whales. Using gross anatomical observation and CT cross‐sectional data, we describe diverse joint morphologies across 74 extant and fossil cetacean taxa. Toothed whales exhibit unfused, partially fused, or fully fused symphyses.

Cleft Lip and Palate Deformity: A Problem Affecting People Around the World [PDF]

open access: yes, 2012
Cleft lip and palate deformities are abnormalities most commonly seen in third world countries. There are many ways to repair them, but first it is determined whether the cleft is unilateral or bilateral.

Clustering crocodylian dental morphology: Insights into functional adaptations, diet, and ontogeny

open access: yesJournal of Anatomy, EarlyView.
Extant crocodylians may be divided into five clusters based on the residuals of four linear dental measurements (y‐axes) and their variation along the jaw (x‐axes). These clusters correlate to snout shape, prey preference, and feeding ecology, particularly prey size and the degree of processing necessary. Multiple families and subfamilies were found in
