An unusual occurrence of bilaterally geminated mandibular second premolars resulting in premolar molarization: A case report.

Rajesh Ebenezar A, Venkatesh A, Mary AV, Mohan AG - J Conserv Dent (2013)

Bottom Line: 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 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.

ABSTRACT
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 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.

Figure 2: Panoramic radiograph revealing premolar molarization in the mandible

Mentions: A 27-year-old, healthy male was reported with the chief complaint of pain in the lower left back tooth region for the past 1 week. Following a clinical examination, molar resembling second premolar tooth were seen in the left mandibular region. A thorough clinical examination confirms the presence of molar resembling second premolar tooth also in the right quadrant due to gemination. This molar resembling second premolar tooth gives the impression of four molars [Figure 1] in both the quadrant. The involved teeth had normal morphology; crowns and roots were significantly developed but smaller in size. The length of the root was normal relative to its crown. The root apex was completely developed. The panoramic radiograph [Figure 2] reveals the presence of single root and single root canal in both the involved mandibular second premolar teeth.
