Primary Failure of Eruption
Conditions
Brief summary
The primary purpose of the study is to identify clinical, radiological and genetic diagnostic criteria for Primary Failure of Eruption (PFE). The secondary purposes are to highlight the genotype-phenotype correlations in the PTHR1 and non-PTHR1 forms and analyze the therapeutic failures.
Interventions
saliva is collected for DNA extraction
panoramic radiography
teleradiography
intraoral X-rays
CT scan of maxillary and mandible
