Radiographic analysis shows obliteration of all pulp chambers short blunted and malformed or absent roots and peri-apical radiolucencies of non carious teeth. Case presentation We present a case of dentin dysplasia type I in a 12-year-old Iranian boy and the clinical radiographic and histopathologic findings of this condition and treatment are described.

The diagnostic features of this rare disturbance will remain incompletely defined until additional cases have been described. Early diagnosis of the condition and initiation of effective regular dental treatments may help these patients to prevent or delay loss of dentition.
