    Dentinogenesis imperfecta type 2 is a rare genetic disorder causing discolored, brittle teeth. This case report details restoring affected teeth with ceramic laminate veneers in a 27-year-old woman.

    Area of Science:

    • Dentistry
    • Genetics
    • Oral Pathology

    Background:

    • Dentinogenesis imperfecta type 2 (DI2), also known as hereditary opalescent dentin, is a rare autosomal dominant disorder.
    • It affects dentin formation during tooth development, leading to characteristic opalescent, discolored teeth.
    • DI2 occurs in approximately 1 in 8000 individuals in the United States.

    Observation:

    • Patients with DI2 exhibit brownish-gray, opalescent teeth causing aesthetic concerns.
    • Affected teeth are prone to chipping and fracture due to abnormal dentin structure.
    • Despite attrition, teeth are not hypersensitive due to sclerotic dentin and pulp chamber obliteration.

    Findings:

    • This case report presents a 27-year-old woman with DI2.
    • The patient's discolored and brittle teeth were successfully restored using ceramic laminate veneers.

  • The restoration addressed both functional and aesthetic deficits.

    • Implications:

    • This case highlights the successful application of ceramic laminate veneers for managing the aesthetic and functional challenges of DI2.
    • Restorative options like veneers can significantly improve the quality of life for individuals with this rare condition.
    • Further research into long-term outcomes of restorative treatments for DI2 is warranted.
