Oral Dysplasia

Oral dysplasia refers to abnormal cellular changes in the lining of the mouth, often considered precancerous. It is commonly identified on the tongue, floor of the mouth, cheeks, or palate. Risk factors include chronic tobacco use, alcohol consumption, human papillomavirus (HPV) infection, and prolonged irritation from dental appliances. Clinically, dysplastic lesions may appear as white (leukoplakia), red (erythroplakia), or mixed patches, and may be smooth, rough, or nodular.

Diagnosis requires careful clinical examination followed by a biopsy, as histopathological evaluation is essential to determine the severity of cellular atypia—mild, moderate, or severe. Early detection is critical because high-grade dysplasia carries a significant risk of progressing to oral squamous cell carcinoma. Management depends on the lesion’s size, location, and severity. Mild dysplasia may be monitored with regular follow-ups, while moderate to severe dysplasia often requires surgical excision or laser ablation. Lifestyle modifications, including cessation of tobacco and alcohol, improve outcomes and reduce recurrence risk.

Regular dental check-ups, patient education, and vigilant monitoring are essential to prevent malignant transformation. Emerging research on molecular markers and imaging techniques may further enhance early diagnosis and personalized treatment strategies for patients with oral dysplasia.
