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 ...

Cementum analysis in cleidocranial dysostosis

open access: yesIndian Journal of Dental Research, 2008
Cleidocranial dysostosis (CCD) is a skeletal disorder associated with dental anomalies such as failure or delayed eruption of permanent teeth and multiple impacted supernumerary or permanent teeth. Absence of cellular cementum at the root apex is presumed to be one of the factors for failure or delayed eruption. The aim of this study was to analyze the
