Outcome Assessment of Patients with Amelogenesis Imperfecta who Received Treatment During the Mixed Dentition Stage

Abstract

Purpose: The purpose of this study was to assess restorative treatment outcomes in the mixed dentition of patients with amelogenesis imperfecta (AI), and to determine post-rehabilitation oral health status and satisfaction of the patients. Methods: Seventy-four restorations placed in permanent incisors and molars in eight subjects with AI met the inclusion criteria. Clinical and radiographic examinations were performed to evaluate the integrity of the restorations and periodontal status post-treatment. Subjects completed a survey regarding esthetics, function, and sensitivity. Results: Among the 74 restorations evaluated, 7 restorations were lost and restorations present comprised of 31 posterior restorations and 36 anterior restorations. Ten were rated clinically unacceptable. Teeth with SSC had moderate gingival index (mean=2.3) and plaque index (mean=2.0) scores. Widening of the periodontal ligament and pulp canal obliteration were common radiographic findings. Subject satisfaction regarding esthetics (P=.002) and sensitivity (P=.03 brushing; P=.01 eating) showed a statically significant difference before and after restorative treatment. Conclusions: During mixed dentition, teeth with AI may be restored with conventional treatment modalities. Direct restorations should be considered “interim” and multiple repairs have to be expected. Post-treatment, gingival inflammation and plaque accumulation were observed. Subjects were satisfied with their appearance and reported a decrease in sensitivity.
