Dentin Dysplasia Type I: A Rare Case Report and Management Protocol

Background and Objective: Dentin Dysplasia (DD) is a rare genetic anomaly that disturbs the formation of dentin and classified into type I (radicular) and II (coronal). Prevalence is approximately 1 in 100,000. DDI is characterized by morphologically normal or slightly amber colored crown with rudimentary root development, improper growth of dentin, obliteration of pulp chamber and periapical radiolucent areas or cysts which can lead to early loss of tooth. Patient Report: An 11-year-old boy, diagnosed with DDI with normal extraoral examination, poor oral hygiene, slightly amber colored crown, class I occlusion with posterior open bite and gingivitis. Teeth number 15 and 31 had caries and the upper canines were not completely erupted. All teeth had short and malformed roots with closed pulp chambers. Conclusion: Treatment plan was oral hygiene improvement and restoration of caries. Due to deep caries and exposure of the pulp horn, access cavity was prepared for tooth number 15. As the pulp chamber was obliterated and root canal therapy was not possible, the access cavity was sealed by MTA and the tooth was restored. No further complication was observed in one year follow up.
