Multilineage Cells from Apical Pulp of Human Tooth with Immature Apex
AbstractThe human tooth with immature apex is a developing organ available for investigation. In this tooth, especially in the apical pulp, the proliferation and differentiation of various cells are activated to make a complete tooth. We investigated the notion that unique cells are included in the apical pulp of human tooth with immature apex.

Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

Intraspecific variation of cochlear morphology in bowhead and beluga whales
Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...

Evaluation of the Accuracy of Different Apex Locaters with 45° Apical Root Resorption
Aim: This study was aimed to calculate the working length (WL) of permanent teeth with simulated 45° resorption of the apical part of the root using four electric apex locaters (EALs): NSK, Woodpecker III, Woodpecker V, and Eighteeth.

Orbital Apex Syndrome with Central Retinal Artery Occlusion Following Tooth Extraction
A 39-year-old male, known diabetic presented with drooping of upperlid and visual loss in the left eye (LE) along with pain in the eye and periorbital region. This was preceded by tooth extraction 2 days back. There was inaccurate projection of rays in the left eye along with complete ptosis, proptosis, relative afferent pupillary defect (RAPD) and ...

A new genus for the Neotropical species of Aesalus Fabricius, with descriptions of eight new species (Coleoptera: Lucanidae: Aesalinae) [PDF]
The Neotropical members of the genus Aesalus Fabricius (Coleoptera: Lucanidae: Aesalinae) are transferred to a new genus, Trogellus, due to their morphological dissimilarity and molecular divergence from the Old World species of Aesalus, and the new ...

Abstract The baphetoids represent a clade of the Carboniferous stem‐tetrapods (Middle Mississippian—Middle Pennsylvanian) with a characteristic extension of the orbits into antorbital vacuities, which formed keyhole‐shaped openings on the skull. The more derived baphetids were crocodile‐like piscivores frequently occurring in coal‐bearing lacustrine ...

Accuracy of an Electronic Apex Locator for Working Length Determination in Primary Anterior Teeth
Objectives: Correct determination of working length is an important step for suc- cess of endodontic therapy. Conventional radiography has limitations in providing the accurate location of apical foramen.
