The characterization techniques used for dental material aids in a better understanding of the composition, density, physical properties, molecular weight, and surface properties of an object. It also helps to analyze and optimize the materials. The structure and properties can be understood by probing and measuring. Many techniques are available and different methods of characterization are being followed. The techniques and also instrumentation are in constant evolution. The objective of this article is to review the usage of various microscopic characterization techniques employed in orthodontics these days, through a careful and updated literature review.
