Amelogenesis Imperfecta and tooth impaction: a retrospective study
Objectives: The aim of this study is to evaluate the prevalence of impacted teeth and to assess the outcomes of different treatment modalities of unerupted teeth among a group of individuals with Amelogenesis Imperfecta (AI)
Methods: This was a retrospective study of 27 patients’ dental records who presented to the school of Dentistry University of Monastir Tunisia from January 2005 to December 2014 and for which the diagnosis of AI was confirmed. A standardized set was used to collect information from each record
Results: Among 27 patients, 13 were male (48.14%) and 14 were female (51.86%). The mean age was 19 ± 7.8. The prevalence of impacted teeth was 85.2% with a total of 161 impacted teeth among the 23 affected patients. Considering the location of the impacted teeth, most of them were impacted in the mandible (53%) than in the maxilla (47%). The most prevalent impacted teeth were the canines (37%), followed by premolars (30%) and molars (23%), while the prevalence of impacted incisors was substantially lower (10.5%). Only six of the 161 impacted teeth were correctly positioned in the arch, representing 3.7% of the success rate. In contrast, 89.4% of the impacted teeth failed to erupt after a duration ranged from 2 to 24 months, depending on the treatment modalities
Conclusions: The prevalence of tooth impaction among individuals with AI was 6 times higher compared with studies involving unaffected people. The number of impacted teeth did not differ significantly between the sexes, modes of inheritance and between different types of AI. Impacted teeth were 1.13 times more likely to occur in the mandible than in the maxilla. The success rate of spontaneous eruption of impacted teeth is considered substantially lower, and it is closely related to the initial vertical position of impacted teeth, causes of impaction and treatment options
