Paediatric dentistry:  Comparative Case Report of Segmental Odontomaxillary Dysplasia and Regional Odontodysplasia

Feedback:  0 comments, 0 ratings


Abstract: The clinical and radiological features of segmental odontomaxillary dysplasia (SOD) are well described but the condition is probably under recognized owing to misdiagnosis as an atypical form of regional odontodysplasia (ROD). Two cases are compared to highlight the differences between SOD and ROD. The clinical, radiographic and histological findings are compared using case reports of a 6-year-old male with SOD and a 4-year-old girl with ROD. Treatment and follow-up for these patients is described, along with a comparative review of the major characteristics of these two rare conditions.

Clinical relevance: To help the paediatric dentist distinguish between these two rare conditions.
