Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Hereditary opalescent dentin [PDF]

open access: yesBMJ Case Reports, 2013
Dentinogenesis imperfecta (DI) is a genetically determined developmental defect of dentine. It is broadly grouped into three categories1: type I: the dental manifestation of osteogenesis imperfect, type II: classical hereditary opalescent dentine and type III: Brandywine isolate opalescent dentine.2 The prevalence of DI is 1:8000. A young patient came

Simulation‐Based Learning in Oral Radiology: Students’ Perceptions of Training in Intraoral Radiographic Techniques Across Two Dental Institutes

open access: yesJournal of Dental Education, EarlyView.
ABSTRACT Objective Simulation‐based learning (SBL) in oral radiology offers a safe, structured environment that supports students’ transition to clinical practice. However, limited research has captured students' perceptions of SBL for intraoral radiography training.

In Vitro Evaluation of Novel Calcium Silicate‐Based and Resin‐Modified Calcium Silicate Materials: Cytocompatibility and Mineralization Potential on Human Dental Pulp Stem Cells for Pulp Repair

open access: yesMicroscopy Research and Technique, EarlyView.
This study demonstrates that Biodentine XP exhibits superior cytocompatibility, promotes odontogenic differentiation, and enhances mineralization in human dental pulp stem cells, supporting its use in regenerative endodontics. Resin‐modified materials showed lower bioactivity, highlighting the importance of material composition in pulp therapy outcomes.

Comparative efficacy of novel bioactive glass versus sodium fluoride toothpaste for dentin hypersensitivity

open access: yesJournal of Periodontology, EarlyView.
Abstract Background This first‐in‐human clinical study aimed to evaluate the safety and efficacy of a bioglass incorporated in a toothpaste, in reducing dentin hypersensitivity (DH) compared to a sodium fluoride (NaF) toothpaste over a 2‐week period. Methods A double‐blind, randomized, parallel‐arm, proof‐of‐concept clinical trial was conducted with 46
