Abstract
Conclusion ROD is a rare odontogenic developmental abnormality of uclear aetiology with anomalies of dentin, enamel and cementum. Both dentitions can be affected. When the clinical pathognomic signs diminish as a result of extraction or surgical intervention, the previous radiography image and past dental history are highly useful diagnostic tools. The main goals of ROD treatment are to improve aesthetics, restore masticatory function, and reduce psychological effects. When treating young adults who have missing teeth, the dental implant can be considered as a promising therapeutic strategy. A more detailed study of ROD is needed to identify possible etiological factors.
