Tooth morphology of deep‐water catsharks of the genus Apristurus (Chondrichthyes: Pentanchidae) in the North Atlantic Ocean

Journal of Fish Biology, EarlyView.
Abstract The deep‐water catshark family (Pentanchidae) is the most species‐rich family among extant shark lineages. Within this family, the genus Apristurus is the largest, comprising small, deep‐sea species characterised by elongated bodies and dorso‐ventrally compressed snouts. Five Apristurus species are currently recognised from the North Atlantic,

The effects of material thicknesses and substrates on the translucency and color masking ability of additively manufactured definitive crown materials

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the translucency of the new 3D‐printable materials concerning thickness and the color masking ability of each material against different substrate colors. Materials and Methods Ninety square‐shaped specimens (12.0 mm × 12.0 mm) of two new 3D‐printable materials: ceramic‐infiltrated hybrid resin composite (VS) and light ...

Egg‐Carrying and Cheliceral Comb in Ibaloniinae Harvestmen From the Solomon Islands (Opiliones: Podoctidae)

Austral Entomology, Volume 65, Issue 3, August 2026.
ABSTRACT Four new species of Ibaloniinae harvestmen are described from the Solomon Islands, Melanesia. Based on the original diagnosis of Euibalonius Roewer, 1915, and description of E. maculatus (Roewer, 1915), this material appeared related to that genus. However, examination of syntype photographs of the type species E.

The dental plate on bichir pectoral fins: A unique dermal skeletal element bearing individual odontodes with tooth‐like replacement

Journal of Anatomy, Volume 249, Issue 1, Page 127-140, July 2026.
Pectoral fins of bichirs encompass the so‐called dental plates – unique dermal skeletal elements with individual odontodes identical to the oral teeth. Abstract The dermal skeleton appeared early in vertebrate evolution in the form of mineralized skin denticles composed of tooth‐like units—odontodes.

Aesthetic Rehabilitation of Anterior Teeth With Molar Incisor Hypomineralization—A Case Report of a New Approach to Selective Removal

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Molar incisor hypomineralization (MIH) is a qualitative enamel defect that can affect not only molars but also anterior teeth leading to both pain and aesthetic problems. There are various treatment options for MIH such as resin infiltration, microabrasion, and resin composite restoration.

One Assay to Rule Them All: Development of a Global Environmental DNA Tool to Support Range‐Wide Surveys of an Imperiled Sawfish and Its Application in the Eastern Tropical Pacific

Ecology and Evolution, Volume 16, Issue 6, June 2026.
To identify promising locations where Largetooth Sawfish, Pristis pristis, may persist, a novel species‐specific Droplet Digital PCR (ddPCR) assay was designed capable of detecting a single copy of DNA, with in silico and in vitro validation experiments indicating functionality across the species' historical range.
