The Effects of Remineralization Agents on Orthodontic White Spot Lesions [PDF]

, 2020
White spot lesions are white opacity on the surface of the tooth enamel which occurs as a result of subsurface enamel demineralization. They occur as a result of several factors such as poor oral hygiene which leads to plaque build up.

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these
