Question

A patient presents with tooth mobility in the mandibular posterior region. Radiographic examination reveals a mirror-like pattern of bone loss. What is the most likely diagnosis?

• A. Localized aggressive gingivitis
• B. Generalized aggressive gingivitis
• C. NOMA
• D. ANUG (Acute Necrotizing Ulcerative Gingivitis)

Hint:

Mirror-image or arc-shaped bone loss on radiographs is a classic feature of localized aggressive periodontitis.

Answer 1

The Correct Option is A

To determine the correct diagnosis for the presented case, let's analyze the information provided:

1. The patient exhibits tooth mobility in the mandibular posterior region.
2. The radiographic examination reveals a "mirror-like" pattern of bone loss.

Based on the symptoms and diagnostic clue offered, let's examine each option:

1. Localized Aggressive Gingivitis:
   • This condition is characterized by rapid attachment loss and bone destruction localized to specific areas, often involving the mandibular anterior teeth or first molars.
   • The mention of a "mirror-like" pattern of bone loss aligns with the characteristic rapid progression of bone loss found in localized aggressive periodontitis.
   • Tooth mobility is a common symptom due to the loss of supporting bone.

   This option matches the provided symptoms and radiographic findings.

2. Generalized Aggressive Gingivitis:
   • While similar to localized aggressive gingivitis, this condition involves generalized rapid attachment loss across multiple sites in the mouth.
   • The question specifies the mandibular posterior region, suggesting localized involvement rather than generalized.

   This option does not match the specific symptom pattern.

3. NOMA:
   • Noma is a rapidly progressive disease causing extensive tissue necrosis and facial disfigurement, mostly affecting malnourished children.
   • It typically does not present solely with tooth mobility or a characteristic pattern of bone loss like in the scenario provided.

   This condition does not fit the description provided in the question.

4. ANUG (Acute Necrotizing Ulcerative Gingivitis):
   • This condition is characterized by ulcerated and necrotic papillae with spontaneous bleeding and pain, along with generalized oral symptoms.
   • Though it may cause some bone loss, it does not typically present with a mirror-like pattern on radiographs.

   This option does not align with the provided radiographic pattern.

Thus, the most likely diagnosis that fits the symptoms and radiographic findings is Localized Aggressive Gingivitis.
