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.

In recent years, three-dimensional (3D) in vitro cell culture models have earned great attention, especiallyin the field of human cancer disease modelling research as they provide a promising alternative towardsthe conventional two-dimensional (2D) monolayer culture of cells with improved tissue organization. In2D cell culture systems, the complexity of cells on a planar surface does not accurately reflects the invivo cellular microenvironment. Cells propagated in 3D cell culture model, on the other hand, exhibitphysiologically relevant cell-to-cell interactions and cell-to-extracellular matrix (ECM) interactions,important in maintaining a normal homeostasis and specificity of tissues. This review gives an overviewon 2D models and their limitations, followed by 3D cell culture models, their advantages, drawbacks andchallenges in present perspectives. The review also highlights the dissimilarities of 2D and 3D modelsand the applicability of 3D models in current cancer research.
