What is Ulcer ? A BREAK IN THE CONTINUITY OF THE COVERING EPITHELIUM – SKIN OR MUCOSA ( A. K. DAS ) A DEFICIT IN THE EPITHELIUM; A WELL CIRCUM- SCRIBED DEPRESSED LESION OVER WHICH THE EPITHELIAL LAYER HAS BEEN LOST ( BURKETT) A DEEP CRATER THAT EXTENDS THROUGH THE ENTIRE SURFACE EPITHELIUM & INVOLVES THE UNDERLYING CONNECTIVE TISSUE ( WOOD & GOAZ )

INVESTIGATIONS • Biopsy • Blood Examination • Culture and antibacterial sensitivity testing • Tzanck test • Viral cultures • Immunofluorescence tests • Darkfield examination for syphilis • Endoscopy • Imaging
HISTOLOGIC PITFALL • LOSS OF EPITHELIUM – WITH NECROTIC • & FIBRINOUS C.T. • ACUTE – PMNL INFILTRATION • CHRONIC – LYMPHOCYTES , PLASMA CELLS, • MACROPHAGES & FIBROBLASTS • HEALING – GRANULATION TISSUE WITH FEW • MACROPHAGES, PLASMACELLS AND • LYMPHOCYTES
PROVISIONAL DIAGNOSIS & DIFFERENTIAL DIAGNOSIS • Many times history and examination alone • Sometimes investigations mandatory FINAL DIAGNOSIS • BASED ON: • INVESTIGATION RESULTS CORRELATED • WITH PROVISIONAL DIAGNOSIS
TREATMENT SYMPTOMATIC DEFINITIVE MEDICAL SURGICAL
Treat the underlying cause. • Remove aetiological factors. • Ensure any possible traumatic element is removed • Prescribe a chlorhexidine 0.2% aqueous mouthwash. • Maintain good oral hygiene. • Topical corticosteroids • Patients should not eat or drink for 30 minutes after using the steroid,in order to prolong contact with the lesion. • Adverse effects are important mainly with systemic steroids.
MANAGEMENT CONDITION DIAGNOSTIC TEST TREATMENT minor aphthous clinical steroid ointment, Aphthasol major aphthous biopsy as needed, hematology if severe steroid ointment or elixir, systemic/injection steroid HSV clinical, cytology, culture, serology oral acyclovir, topical pencyclovir erythema multiforme clinical, HSV IgG for recurrence oral steroid, oral acyclovir if HSV+ erosive lichen planus biopsy topical or oral steroid, DMDs pemphigus biopsy, DIF, IIF oral steroid, DMDs pemphigoid biopsy, DIF topical or oral steroid, dapsone malignancy biopsy surgery, irradiation infection biopsy, culture antimicrobial as indicated Back
