Dental anomalies can be caused by any etiological factor that interrupts
odontogenesis. Leaving environmental factors aside, genetics have been found to be a
factor at various levels in dental anomalies and the fact that some human dental
anomalies are often seen together supports the evidence that there is shared genetic
control of disturbances in dental development. Early diagnosis can be assisted by
recognition of dental anomalies (e.g. peg shape lateral incisors) in early mixed
dentition that have a genetic association with canine impaction. Early detection of
palatal canine displacement will allow clinicians to focus on prevention of canine
impaction. The purpose of this chapter is to approach the early diagnosis and
appropriate orthodontic intervention of dental anomalies and tooth impaction.
