Vitamin C‐Induced Photo‐Redox Threshold Enables High‐Fidelity Volumetric Printing of Collagen

Advanced Materials, EarlyView.
Tomographic volumetric printing (TVP) of native proteins is limited by uncontrolled background crosslinking. Here, vitamin C is introduced as a biocompatible redox regulator to establish a tunable nonlinear polymerization threshold response for TVP.

Occurrence of Second Mesio-buccal Canal in Maxillary First Permanent Molar: A CBCT Study

Orthodontic Journal of Nepal, 2017
Introduction: Complexity in root canal morphology leads to chances of failure in endodontic treatment due to missed canal. Availability of Cone-beam Computed Tomography (CBCT) has contributed to assess second mesiobuccal canals in maxillary first molars.
