Summary

This case report details a rare case of hypoplastic maxillary first premolar in a 10-year-old boy. The condition, affecting only the mesial aspect, was potentially caused by infection or extraction trauma.

Area of Science:

  • Dentistry
  • Pediatric Dentistry
  • Dental Radiology

Background:

  • Dental hypoplasia is a developmental anomaly affecting tooth enamel or dentin.
  • Maxillary first premolars are critical for occlusion and facial aesthetics.
  • Early childhood dental trauma or infection can impact permanent tooth development.

Observation:

  • A 10-year-old boy presented with a radiographically diagnosed hypoplastic maxillary first premolar.
  • The hypoplasia was localized to the mesial aspect of the developing permanent tooth.
  • The patient had a history of primary maxillary first molar extraction.

Findings:

  • The unusual distribution of hypoplasia suggests localized developmental insult.
  • Potential causes include infection from the primary first molar's mesiobuccal root or trauma during extraction.
  • Radiographic diagnosis was key in identifying the specific pattern of hypoplasia.

Implications:

  • Understanding localized hypoplasia aids in differential diagnosis for developmental dental defects.
  • Management involved restorative treatment using dentine adhesive and composite material.
  • This case highlights the importance of considering iatrogenic factors in tooth development.
