• The primary dentition completes root formation by 3 years of age, and the stable period clinically for primary dentition occurs before root formation is completed by age 3 years.
• The crowns of primary anterior teeth are wider mesiodistally in comparison with their cervicoincisal length than are the crowns of permanent teeth.
• The roots of the primary anterior teeth are narrower mesiodistally.
