Study Notes
Physical and Dental Changes in Children Aged Three to Six Years
- During this period, children experience physical changes in their body and craniofacial structure.
- Boys are generally taller and heavier than girls.
- The growth of the head and face continues, resulting in a larger, wider, longer, and more detailed face.
- The primary incisors are more upright than the permanent incisors.
- The soft tissue prominence of the nose and mandible increases, while overall facial convexity reduces.
- The maxillary growth between 3 to 6 years is mainly in the transverse direction.
- 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.
- The cervical ridge buccally on the primary molars is much more pronounced, especially on both the maxillary and mandibular first molars.
- The roots of the primary molars are more slender and longer than the roots of the permanent teeth, and flare out more apically.
- The primary teeth are usually lighter in color than the permanent teeth.
