Inverted impaction of a mandibular premolar associated with a dentigerous cyst: report of a case

Inverted impaction of mandibular premolars is reported to be rare; its prevalence has not been quantified. Here we report a case in which a 12-year-old female presented with an inverted impacted manibular premolar associated with a dentigerous cyst. The likely aetiology and management of this condition is discussed. CLINICAL RELEVANCE: This case highlights the need for clinicians to be aware of the rarer causes of apparent absence of teeth from the arch and the importance of taking radiographs prior to treatment planning.
