Dentin dysplasia is a rare defect of dentin development with an autosomal dominant pattern of inheritance, which is generally divided into 2 main classes based on the clinical and radiographic appearance of the affected dental tissues: type I, which affects the root portion and type II, which affects the coronal portion of the tooth dentin dysplasia (type 1) associated with sclerotic bone and skeletal anomalies, and in- herited as an autosomal dominant trait in a brother and sister. Prevalence of this condition is reported to be approximately 1 in 100,000 patients 1. Teeth becomes weaker due to this condition Dentin dysplasia, a rare anomaly, is an autosomal dominant hereditary disturbance in dentin formation affecting either the primary or permanent dentitions.
