Multiple eruptive delay as a variant of primary eruption failure. A preliminary case report.

Primary failure of eruption (PFE) is an autosomal disease that occurs in approximately 0.06% of the population and is defined as the malfunction of dental eruptive mechanisms with delay and absence of these processes in a non-ankylosed tooth. Treatment options for patients with eruptive delays range from prosthetic to surgical interventions.

Dentigerous cyst and the importance of early detection. report of a pediatric case.

Dentigerous cysts are a common cystic pathology that develop between the first and third decade of life and are mainly associated with impacted or erupted mandibular third molars followed by maxillary canines and maxillary third molars. These kinds of cysts are the result of the proliferation of enamel epithelium after its formation, the pathogenesis of which is not clear. Few of these cysts have been reported in pediatric patients.
