Parry-Romberg syndrome (PRS) or progressive facial hemiatrophy is a developmental craniofacial disorder of unknown etiology characterized by a slowly progressive unilateral facial atrophy. It is associated with different systemic manifestations particularly, maxillofacial, neurologic and ophthalmologic abnormalities. Dentists must be aware of PRS to identify this invalidating disorder. In this article, we review the etiology, clinical features (especially craniofacial and dental manifestations) and treatment of PRS. We searched in PubMed line using specific words such as PRS from 2008 to 2014 (August). We identify 14 papers have described oral manifestations of this syndrome. We excluded all the article papers that did not indicate to oral manifestations of PRS.
