Relation Between Sella Turcica Bridging and Palatal Canine Impaction – A Review

Anatomical variations in sella turcica are associated with various types of syndromes, craniofacial, and dental abnormalities. The one of interest to orthodontists is palatal impaction of canine. It has been advocated that the dental progenitor cells and anterior wall of the sella-turcica share a common embryological origin, and neural crest cells play an important role in the development of both. The early diagnosis and intervention for impacted canines can reduce the duration, expense, and complexity of treatment in the permanent dentition. A proper knowledge of normal variants and pathologies that are associated with sella turcica bridging is required. Lateral cephalograms and CBCT should be studied thoroughly to observe the presence of STB and its association with PCI. The present review aimed at getting a much clearer association of bridging of sella turcica with palatal impaction of canine.
