Conditions

Primary Failure of Eruption

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.
