The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Area of Science:

  • Dentistry
  • Developmental Biology
  • Genetics

Background:

  • Regional odontodysplasia (ROD) is an uncommon developmental anomaly affecting ectodermal and mesodermal tooth components.
  • It typically presents as localized hypomineralization and structural defects in teeth.

Observation:

  • A five-year-old female presented with malformed primary teeth, including hypomineralized enamel, crown destruction, discoloration, and enamel opacity.
  • Radiographic examination revealed thin radioopaque contours, poor enamel-dentine distinction, and enlarged pulp chambers in affected primary teeth.
  • Developing permanent teeth exhibited delayed eruption and a characteristic "ghost appearance."

Findings:

  • The case demonstrates the varied clinical and radiographic manifestations of regional odontodysplasia in primary and permanent dentitions.
  • Successful management involved extraction of severely affected primary molars, placement of a stainless steel crown, and a caries prevention program.

Implications:

  • Paediatric dentists must recognize ROD as it affects both primary and permanent teeth, often necessitating multidisciplinary care.
  • Early diagnosis and comprehensive management are crucial for preserving oral health and function in children with ROD.
