Clinical Findings and Management of a Rare Case of Multivariate Type of Dentinal Dysplasia: A Case Report

Dentinal dysplasia is a rare autosomal dominant condition affecting both deciduous and permanent dentitions. The presentation of dentinal dysplasia can be varied and intriguing. It is subdivided into two types and shares similar characteristics with dentinogenesis imperfecta and its variations. Marked radiographic similarities have been reported between dentinal dysplasia and dentinogenesis imperfecta. We present a case of a 26-year-old man who presented at our clinic with clinical features identical to those of aggressive periodontitis, accompanied by clinical and radiographic features commonly associated with both type 1 and 2 dentinal dysplasia. As the condition had not been reported previously in the literature, we believe the term “multivariate generalized dentinal dysplasia” would describe this unique condition accurately. The treatment plan was complex, aided by biomarker evaluation to time the treatment chart, which included extraction of selected teeth, periodontal surgery involving bone grafts, splinting, local delivery of medications, laser-assisted debridement, and regular follow-up appointments. Hereditary dentinal abnormalities are rare and are observed in people of different ethnicities with varied presentations. The treatment of these conditions is challenging and demanding, as most patients are in an active disease state. Biomarker assessment during treatment planning plays a critical role in long-term clinical outcomes.
