Spontaneous alignment of permanent successors after enucleation of odontogenic cysts associated with primary teeth.

Pulpotomy and pulpectomy occasionally lead to cyst formation in the primary dentition. They show specific clinical features of large size, rapid growth, buccal expansion and displacement of permanent teeth. Complete enucleation of the cyst with extraction of the associated primary teeth and preservation of the permanent teeth appeared to be the most suitable treatment option. Normal alignment of the permanent teeth occurred spontaneously even their initial positions were highly unfavourable.
