A clinical study of 341 patients with oral lichen planus in North Bengaluru population

Background: Lichen planus is a chronic autoimmune disorder affecting the oral mucosa, skin, genital mucosa, scalp, and nails; most often seen affecting peri-menopausal women. This study provides useful data regarding the prevalence of oral lichen planus (OLP) in the North Bengaluru population including its type and gender distribution. Aims and Objective: To provide useful data regarding the prevalence of OLP in the North Bengaluru population including its type and gender distribution (March 2013 to April 2016). Methods: This hospital-based study recorded the cases which reported to the Department of Oral Medicine and Radiology March 2013 to April 2016. 341 cases of histologically confirmed OLP were analyzed for their gender and clinical form distribution as well as certain other parameters such as intraoral site involvement and symptoms. Results: This study showed females being more affected by OLP with buccal mucosa being the most commonly involved site intraorally. The reticular form was the most common which was detected incidentally and erosive and atrophic forms showed maximum associated symptoms. Conclusion: This study has highlighted the distribution of OLP among the Bengaluru population. Lichen planus is a white lesion of oral mucosa which can pose a confusing array of forms thereby mimicking other diseases. A long time follow-up is of utmost importance to detect its malignant transformation.
