Which dental condition may show a slide of blue sclera in its diagnosis?

The condition associated with a slide of blue sclera is dentinogenesis imperfecta, which is a genetic disorder affecting the development of dentin in teeth. The blue sclera occurs in this condition due to the underlying connective tissue disorder that is often present. The sclera appears blue due to the translucency of the thin, dysplastic sclera over the underlying choroidal tissues.

In dentinogenesis imperfecta, the enamel may also be affected, but it’s primarily the dentin that undergoes abnormal development leading to teeth that are discolored (often appearing opalescent or bluish) and prone to fractures. The association between blue sclera and dentinogenesis imperfecta can assist in diagnosis when evaluating a patient with dental abnormalities.

While amelogenesis imperfecta affects enamel and dental fluorosis results from excess fluoride during tooth development, they do not present with blue sclera. Hypophosphatasia affects the mineralization of bone and teeth, but it also does not typically involve the blue scleral appearance. This distinctive feature of blue sclera helps healthcare professionals in identifying and managing the associated dental implications effectively.
