A distinctive clinical feature of Dentinogenesis Imperfecta is cervical constrictions. This condition is characterized by abnormalities in dentin formation, leading to a variety of oral manifestations. One key feature is that the dentin is often not properly formed, resulting in a constricted appearance at the cervical area of the teeth, which is the region where the tooth crown meets the root. This can lead to aesthetic concerns as well as functional issues, such as increased susceptibility to wear and breakage.

While reduced root size can be an associated feature and color changes in enamel may occur, these are not as specifically indicative of Dentinogenesis Imperfecta as cervical constrictions are. Localized swelling of the gums is more indicative of periodontal conditions rather than the intrinsic dental tissue defects seen in Dentinogenesis Imperfecta. Thus, cervical constrictions stand out as a hallmark sign of this condition in patients.
