Fish Scales: A Multifunctional Biomaterial from Nature
ENERGY &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 ...

Tracing the evolution of root coverage: Clinical milestones leading to a minimally invasive era
Journal of Periodontology, EarlyView.Abstract Over the past several decades, periodontal plastic surgery has undergone a remarkable transformation, particularly in the field of root coverage procedures. This review traces the historical evolution of surgical techniques, from the early use of pedicle flaps and free gingival grafts (FGGs) to the development of bilaminar approaches ...
