Primary failure of eruption in permanent first molar treated surgically - A case report

Primary failure of eruption (PFE) is a cessation of tooth eruption before emergence, despite the presence of clear eruption pathway. It is a rare disease with a prevalence of 0.06%. However, Decker et al showed that the genetic mutation in PTH1R gene is associated with primary failure of eruption. This case report is about a nine years old female patient who reported to the Department of Pediatric Dentistry, Pakistan Institute of Medical Sciences (PIMS), Islamabad, with primary failure of eruption of right mandibular 1st permanent molar which was incidentally found on OPG, with a completely erupted left 1st permanent molar. Treatment commenced after one year of patient's initial presentation with no progress in eruption. The affected tooth was marsupalized completely including the removal of the dental sac and coronal bone. After the follow up period of 4 months tooth eruption was evident. Further follow up of 8months revealed complete tooth eruption.
