Study Notes
Origin of Pedodontics
- The term "Pedodontics" originates from the Greek words "paidos" meaning child and "odous" meaning tooth.
Focus of Pedodontics
- The primary focus of Pedodontics is the development, eruption, and maintenance of healthy teeth and surrounding oral tissues in children.
Factors Influencing Tooth Formation and Eruption
- Genetic, environmental, and hormonal factors can influence the formation and eruption of teeth.
Tooth Eruption Process
- The approximate time interval for a permanent tooth to move toward occlusion after crown completion is around 2-3 years.
- The process of movement of the tooth through the tissues of the jaw towards occlusion is known as tooth eruption.
- Tooth eruption is a complex process influenced by multiple factors, including genetic, environmental, and hormonal factors.
Pre-eruptive Tooth Movement
- The primary purpose of pre-eruptive tooth movement is to position the tooth germ in the correct location for eruption.
Axial Movement
- The axial movement of the tooth from its crypt within the bone of the jaw to its functional position in occlusion is called axial migration.
Theories of Tooth Eruption
- The hydraulic theory suggests that an increase in tissue fluid or blood pressure in the periapical region is sufficient to move the tooth.
- The eruption theory suggests that bone resorption and formation occur due to eruptive forces applied by the tooth over the bone.
Post-eruptive Tooth Movement
- The primary function of post-eruptive tooth movement is to adjust the tooth's position to achieve optimal occlusion.
Types of Tooth Movement
- Asymmetric movement occurs when one part of the tooth germ remains fixed while the rest continues to grow, causing a shift in the center of the tooth germ.
- Active movement causes bone resorption at the direction of tooth movement and bone apposition behind it.
Root Growth Theory
- According to the root growth theory, the root was suggested to transmit the force to cause eruption, but was never found histologically.
Fibroblasts and Tooth Eruption
- Fibroblasts have been considered a factor in tooth eruption due to their traction power.
