There is a spectrum of treatment need in patients with amelogenesis imperfecta (AI). This Swedish study reports on the condition of 15 patients with AI aged 14–37 yrs (mean 23). Ten patients had hypoplastic type AI, and 5 had hypomineralised type. The patients had 403 teeth, of which 213 had restorations.

The restorations included 10 gold crowns, 121 metal-ceramic crowns, 28 ceramic crowns, 18 porcelain onlays or inlays, and 36 porcelain veneers. Only 1 crown was rated unsatisfactory according to CDA criteria for surface, colour, anatomical form and marginal integrity, and most restorations were graded excellent in all respects.

There had been 10 prosthetic complications of cementation or fracture, and in 1 patient, 11 crowns had been remade because of caries. Minor periodontal problems were noted. Patients had been very concerned about their teeth in adolescence, but treatment had greatly improved this. Seven patients felt the best age for treatment was between 10 and 15 yrs, and others, up to 25 yrs..
