How does Dentinogenesis imperfecta affect dental management?

Primary molars: Early full-coverage restorations (stainless steel crowns) on primary molars to prevent wear
Anterior and severe wear: Composite or crowns for anteriors; overlay dentures if wear is severe
Pulp assessment: assess pulpal and periapical status even without visible caries.
Endodontics: narrowed or obliterated canals can make treatment difficult; consider specialist input before deciding the tooth is untreatable.
Extraction: Plan extractions from root shape, length, and remaining structure, using an atraumatic technique
With osteogenesis imperfecta: plan safe positioning and gentle handling.
Antiresorptive treatment: if osteogenesis imperfecta is present, review treatment and coordinate invasive care with the medical team; drug exposure alone does not determine extraction eligibility.

Feature	Dentinogenesis imperfecta	Amelogenesis imperfecta
Primary tissue defect	Dentin; enamel chips off weakened support.	Enamel thickness, mineralization, or maturation.
Radiographic clue	Bulbous crowns, cervical constriction, short roots; usually obliterated pulps.	Thin or poorly mineralized enamel; some forms have taurodontism.
Important exception	Type III may have enlarged pulps or shell teeth.	Pulp shape is not invariably normal.
Dental priority	Protect against rapid wear; assess silent periapical disease.	Protect sensitivity and weak enamel; stage restorations through growth.
