Oral medicine is a specialty focused on the mouth and nearby structures. It lies at the interface between medicine and dentistry.Oral medicine is concerned with clinical diagnosis and non-surgical management of non-dental pathologies affecting the orofacial region (the mouth and the lower face).
Many systemic diseases have signs or symptoms that manifest in the orofacial region. Pathologically, the mouth may be afflicted by many cutaneous and gastrointestinal conditions. There is also the unique situation of hard tissues penetrating the epithelial continuity (hair and nails are intra-epithelial tissues). The biofilm that covers teeth therefore causes unique pathologic entities known as plaque-induced diseases.
