Developmental Disturbances in Teeth

Developmental disturbances of teeth means any abnormality of the teeth where the pathology starts in the embryonic stage of human life, during the formation of the dentition. Developmental disturbances are caused due to multiple factors like Trauma during development, tumor in the pitutary gland, heriditary, hormonal imbalances dueing development etc. 

Developmental disturbances in teeth are of 5 types based on the feature of the tooth they affect:

  • Size of Teeth
  • Shape of Teeth
  • Number of Teeth
  • Structure of Teeth
  • Growth (Eruption) of Teeth

Here i will just give the overview on what the abnormality is called which will be discussed in detail in the upcoming posts.

Size Of Teeth:

The developmental disturbance of teeth where the size is either smaller or larger than normal teeth. This can be either generalized or localized based on the etiology. 

  1. Microdontia
  2. Macrodontia

Shape Of Teeth:

There are many developmental changes in which the shape of the tooth can be affected, the Enamel, Dentin, Crown, Root etc can be affected together or seperately. 

  1. Germination
  2. Fusion
  3. Concrescence
  4. Di laceration
  5. Talon cusp
  6. Dens in Dente
  7. Dens Evaginatus
  8. Taurodontism
  9. Supernumerary Roots

Number Of Teeth:

This is one of the common anamolies seen in oral cavity where, there are either increased number of teeth that is more than 32 or less than the normal. The most commonly missing teeth is the Lateral incisor. 

  1. Anodontia
  2. Supernumerary Teeth
  3. Pre-Decidious Teeth
  4. Post-Permanent Teeth

Structure Of Teeth:

  1. Amelogenesis Imperfecta
  2. Environmental Enamel Hypoplasia
  3. Dentinogenesis Imperfecta
  4. Dentin Dysplasia
  5. Regional Odontodysplasia
  6. Dentin Hypocalcification

Growth (or) Eruption Of Teeth:

  1. Premature Eruption
  2. Delayed Eruption
  3. Eruption Sequestrum
  4. Multiple Unerupted Teeth
  5. Embedded and Impacted Teeth
  6. Ankyolosed and Decidious Teeth.
