Molecular biology is a rapidly developing field of science. Advancements in molecular biology have helped various other fields including medicine and dentistry to go molecular. Since the introduction of molecular biology in orthodontics and the identification of genes associated with growth and development the focus has shifted towards a personalized treatment approach. The genes which have been linked to malocclusions and developmental disorders can serve as targets for an individual based treatment. Researchers have also been able to discover the molecules involved in orthodontic tooth...
