decreases the duration of the lesions.Topical anesthetics,antibiotics,mouthwashes,etc.,have been used.In severe cases,intralesional steroid injection or systemic steroids in a low dose(10-20 mg prednisone)for 5-10 days reduce the pain dramatically.,BACK,III.Behets disease,1.Preface Hulusi Behet(1937)Behets disease is a chronic multisystemic inflammatory disorder of uncertain cause and prognosis.2.Etiology Unknown,NEXT,3.Clinical features 1)oral mucosa:minor aphthous ulcer 2)genital lesion:ulcer 3)skin lesions:erythema nodosum,epifolliculitis,pustule after needling 4)ocular

perivascular mononuclear cellular infiltrate,endothelial cell swelling or necrosis,partial luminal obliteration and occasional fibrinoid necrosis of the vessels.,NEXT,5.Diagnosis 1)recurrent oral ulceration 2)recurrent genital ulceration 3)eye lesions 4)skin lesions 5)positive pathergy test To establish the diagnosis of Behets Disease,recurrent oral ulceration plus any two of the other four major clinical criteria must be present.,NEXT,6.Differential diagnosis,NEXT,RAU Herpetic atomatitis Crohns diseaseReiters syndromeStevens-Johnson syndrome,7.Treatment Symptomatic in mild cases.Systemic steroids,immunosuppressive drugs,colchicines,thalidomide,and dapsone are administered in severe cases.,BACK,IV.Traumatic Ulcer Traumatic Bulla,1.Preface,Because of the constant motion of the masticatory mucosa over the teeth and the introduction of hard objects into the oral cavity,traumatic ulcers are frequent.,NEXT,2.Etiology,Mechanical factors:a sharp or broken tooth,rough fillings,clumsy use of cutting dental instruments,hard foodstuffs,sharp foreign bodies,biting of the mucosa,and denture irritation etc.Physical factors:thermal burnsChemical factors:strong acid,strong

stomatitis.,NEXT,6.Treatment,It is nonspecific and symptomatic.Non-steroidal anti-inflammatory drugs,salicylates,and tetracyclines may be helpful,cyclosporin,azathioprine,methotrexate,and systemic steroid in severe case.,BACK,Summary,To compare the characteristics of major Aphthous ulcer,traumatic ulcer,carcinoma and tuberculous ulcer.(etiology,pathology,clinical feature,treatment,prognosis).To master the treatment principle of ulcerative diseases by taking RAU for example.,NEXT,To master the effect,usage,contraindication and side-effect of corticosteroid in treating ulcerative diseases.To establish the conception of oral mucosal syndrome by means of learning Behets disease.,NEXT,Questions,Which is the most common form of Recurrent Aphthous Ulcer?Whats the characteristic of its lesion?Whats the effect of corticosteroid in treating oral ulcerative diseases?Whats the primary treatment to traumatic ulcer?,NEXT,Taking major Aphthous ulcer and carcinoma for example,try to tell the difference between benign ulcer and malignant ulcer.What are the oral lesions of Behets Disease and Reiters Syndrome?What are their clinical systemic features?,BACK,
