Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite
Advanced Functional Materials, EarlyView.The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Bilateral fusion of permanent mandibular incisors with talon's cusp
SRM Journal of Research in Dental Sciences, 2017 Fused teeth and talon cusp are developmental anomalies with inherently bizarre anatomy. These anomalies may develop during tooth bud morphodifferentiation as a result of a developmental aberration of both the ectoderm and mesoderm.

Advanced Science, EarlyView.Matrix stiffness softening is identified as a previously underappreciated feature in deep caries. Higher stiffness drives exosome release in dental pulp stem cells through a coordinated mechanism involving PI3K–AKT‐regulated Baiap2 and kinesin‐1, thereby promoting odontogenic differentiation.
