Summary
Regional odontodysplasia (ROD) is a rare dental anomaly affecting both primary and permanent teeth. This case highlights its presentation and successful management in a young child, emphasizing early intervention.
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.
