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