Abstract
Oral lichenoid lesions or reactions (OLLs/OLRs), which are clinical and histological contemporaries of the traditional oral lichen planus (OLP), had already garnered a great deal of attention in the literature. In contrast to idiopathic OLP, OLLs frequently have a definite, recognizable initiating component. Although a cursory clinical and histological evaluation of lesions frequently demonstrates numerous similarities with OLP, relatively new data has demonstrated that distinct features exist and serve as the foundation for the majority of categories. Although many systemic pharmaceuticals can lead to end oral lichenoid reactions, medications for diabetes, hypertension, nonsteroidal anti-inflammatory, antimalarial, and antifungal treatments are frequently blamed. Oral drugs, metallic dental restorations, acrylates, composite resins, glass ionomer cement, cinnamates, flavorings, and other chemical substances have all been associated when in direct contact. The objective of the case report is to elaborate the correlation between the oral lichenoid reaction and the use of hair dye. The incident under consideration is significant because the majority of past reports of allergic reactions to hair dye involved the face and scalp rather than the oral cavity. This report recommends that oral physicians inquire about the patient's use of cosmetics during history-taking whenever dealing with abrupt inflammatory responses in the orofacial area in order to diagnose and treat lesions more efficiently.
