Severe Impaction of the Primary Maxillary Second Molar Along with Horizontal Impaction of the Permanent First Premolar - A Rare Case Report

Aim: The purpose of this case report is to present a case of a totally impacted maxillary second molar and horizontally impacted first premolar.

Background: Impaction of deciduous teeth is an uncommon event. Various factors which lead to the impaction of a deciduous tooth include ankylosis, congenitally missing permanent teeth, defects in periodontal membrane, trauma, defects in eruptive forces or a combination of all these factors.

Report: A 12-year-old male patient reported to the department with a chief complaint of pain in the upper left back teeth region. On clinical examination, first premolar tooth was missing. Panoramic and maxillary occlusal radiographs revealed a horizontally impacted first premolar close to the inferior wall of the maxillary sinus and a vertically impacted second deciduous molar embedded within bone close to the inferior wall of the maxillary sinus between 2nd premolar and 1st permanent molar.

Conclusion: The complete impaction of deciduous teeth is a rare condition and very few cases have been reported in the literature. This case reports a totally impacted maxillary second deciduous molar along with a horizontally impacted 1st premolar tooth and its surgical management.
