This case report details a rare simultaneous occurrence of dens invaginatus (DI) and gemination in a single mandibular incisor. Early radiographic examination is crucial for diagnosing these dental anomalies.

Area of Science:

  • Dentistry
  • Developmental Biology
  • Oral Pathology

Background:

  • Dens invaginatus (DI) is a developmental anomaly of enamel organ invagination, typically affecting maxillary lateral incisors.
  • Gemination involves a single tooth bud attempting to divide, rarely occurring in mandibular teeth.
  • The simultaneous occurrence of DI and gemination in a mandibular tooth is exceptionally rare.

Observation:

  • A 13-year-old female presented with spontaneous pain in her mandibular left lateral incisor.
  • Clinical examination revealed an enlarged tooth with an incisal edge notch.
  • Radiographic analysis confirmed a Type 2 dens invaginatus within a Type I geminated mandibular left lateral incisor.

Findings:

  • The study identified a rare concomitant presentation of dens invaginatus and gemination.

  • The affected tooth exhibited radiographic signs of both developmental anomalies.
  • This combination highlights the variability of dental anomalies.

    • Implications:

    • Dens invaginatus can lead to pulpal complications like pulpitis and periapical lesions, often asymptomatic.
    • Clinicians must consider DI in teeth with unexplained pulpitis, even without trauma or caries history.
    • Radiographic evaluation of suspicious teeth and surrounding periodontium is essential for accurate diagnosis and management.
