Bilaterally geminated mandibular 2nd premolars resulting in
Gemination refers to an attempt by a single tooth bud to divide, with a resultant formation of either a large tooth with a bifid crown or two completely divided teeth throughout the crown and root.

This report, published in the Journal of Conservative Dentistry, describes a rare case of bilateral gemination of permanent mandibular second premolar tooth giving rise to molarization of premolars.

The mesiodistal width of these teeth is similar to mandibular molars, but the cervicoocclusal width is lesser than that of the molar tooth. This paper also discusses the potential orthodontic, periodontal, and endodontic complications of premolar molarization.
