Desquamative gingivitis (DG) is a manifestation of a number of mucocutanenous disorders, one of it being oral lichen planus (OLP). OLP is an autoimmune disease. The aetiology for this condition is unknown, but there are few factors associated with its occurrence, for example alcohol drinking, smoking, allergic reaction to certain medications or restorative material. DG lesions increase the long-term risk for plaque-induced periodontal disease. At the same time, dental plaque and calculus cause gingival OLP resulting in the erosive disease. This report presents the management of a case of oral lichen planus associated with desquamative gingivitis with periodontitis. The expertise involved are from the oral medicine, periodontic and prosthodontic clinics. The uniqueness of the case management was the introduction of single tufted brush, Tepe® compact tuft toothbrush, to perform “solo brushing technique”. It was able to remove plaque effectively and did not cause irritation to the gingivae. Patients presenting with mucocutaneous disorders which exarcebates other oral conditions requires multidisciplinary management. Proper treatment planning will significantly improve their oral health related quality of life.
