Summary

A chin sinus, often a sign of a chronic dental abscess, can be misdiagnosed. This case study highlights its dental origin in twins, with successful treatment through root canal therapy and surgery.

Area of Science:

  • Dentistry
  • Oral Pathology
  • Dermatology

Background:

  • Chin sinus (median mental sinus) can stem from chronic apical abscesses of mandibular anterior teeth.
  • The dental origin is often asymptomatic, leading to misdiagnosis by non-dental professionals.

Observation:

  • This study reports a rare case of median mental sinus of dental origin in twins.
  • One twin experienced resolution after root canal therapy alone.

Findings:

  • The other twin required both root canal therapy and surgical intervention to eradicate the infection.
  • This underscores the importance of considering dental pathology in cases of persistent chin sinus.

Implications:

  • Accurate diagnosis of median mental sinus requires a dental evaluation to address the underlying cause.
  • Timely dental treatment can prevent unnecessary surgical procedures and ensure complete healing.
