“…All authors advocate an extensive periapical follow‐up of endodontically treated patients diagnosed with DGI/DD. As far as the prognosis of endodontic treatment in DGI/DD is concerned, most reports show this to be very poor: the majority of treated teeth (especially in DGI) are eventually extracted .…”

Dentin defects represent a cluster of relatively rare heritable disorders affecting the formation and mineralization of dentin. Major clinical features include loss of enamel with extreme wear of exposed dentin, opalescent tooth discoloration, short roots with pulpal calcification and increased tooth mobility, and frequent periapical radiolucencies. Historically, these inherited conditions have been classified by Shields et al. (1) as either dentinogenesis imperfecta (DGI) types I, II and III, or dentin dysplasia (DD) types I and II. DGI type I is now universally designated as osteogenesis imperfecta with dentinogenesis imperfecta (OI/DGI) and is caused by type I collagen mutations. Among the genes expressing the non‐collagenous proteins in dentin, only the DSPP gene has been implicated in the etiology of DD type II and all DGI types, suggesting that heritable dentin defects can be viewed as a continuum rather than as distinct disease entities. Dental treatment strategies should aim to preserve the affected dentitions by protecting teeth from wear, restoring them to compliance with the specific structural characteristics of the defective dentin, and anticipating early tooth loss. Endodontic treatment of the affected teeth is very challenging because of the peculiar pulp morphology and most often has poor prognosis. If conventional therapy is not an option, periapical curettage and retrograde filling is a possible alternative, except in the case of teeth with short roots.

“…Convincing data are still lacking with respect to the incidence of periapical pathosis being a hallmark of DGI‐III and DD‐I. Long‐term follow‐up studies on this subject are scarce and suggest a very poor prognosis for endodontically treated teeth in patients with these conditions .…”
