Area of Science:

  • Dentistry
  • Dental Morphology
  • Human Anatomy

Background:

  • A central cusp is a supernumerary tubercle on the occlusal surface of a molar.
  • Central cusps are most commonly observed in premolars.
  • Research on central cusps in molars, particularly the lower second molar, is scarce.

Observation:

  • This study documents the presence of a central cusp on the lower second molar.
  • The observed cases were found bilaterally.

Findings:

  • The central cusp is a rare dental anomaly.
  • The lower second molar is an infrequent location for this anomaly.
  • This report supplements existing literature on molar central cusps.

Implications:

  • Understanding rare dental anomalies like the central cusp is crucial for accurate diagnosis.
  • Further research into the prevalence and etiology of central cusps in molars is warranted.
  • This case report contributes to the dental community's knowledge base on tooth morphology variations.
