Mucosal Changes Induced by an Unregulated Orthodontic Retainer: Clinical and Diagnostic Insights –A Case Report

Abstract

Background: Lobular capillary hemangioma (LCH), previously termed pyogenic granuloma, is a benign vascular lesion frequently triggered by chronic irritation or trauma. While commonly affecting the gingival tissue, its occurrence on the palatal mucosa due to orthodontic appliances is rare.

Case Presentation: We present a case of a 28-year-old male who developed a firm, non-ulcerative swelling in the anterior hard palate. The lesion arose due to continuous irritation from an unregulated clear orthodontic retainer provided by a non-certified establishment. Clinical examination revealed a pale pink, lobulated mass with erythematous areas and indentations from the mandibular anterior teeth. Surgical excision under local anesthesia was performed, preserving the nasopalatine neurovascular bundle. Histopathology confirmed the diagnosis of lobular capillary hemangioma.

Discussion: The lesion’s development underscores the importance of standardized orthodontic protocols and the risks  associated  with unsupervised  treatment.  Differential  diagnoses  included irritational fibroma,  pyogenic granuloma, and neurofibroma. This case highlights the role of chronic mechanical irritation in reactive lesion formation and the critical need for early intervention and histological confirmation.

Conclusion: Capillary hemangiomas,  though  benign  and  asymptomatic,  require  accurate  diagnosis and management to prevent recurrence. This case reinforces the significance of professional oversight in orthodontic therapy and the potential complications of substandard care.
