  1. by dr.linda Maher INTRODUCTION TO ORAL MEDICINE

  2. ORAL MEDICINE It is the dental specialty that is concern with diagnosisand non surgical management of non dental pathologies and conditions affecting the oral and maxillofacial region

  3. . Dentist and dental hygienist can make preliminary diagnosis of systemic disease because many systemic disorders have oral manifestations

  4. FIELDS OF ORALMEDICINE 1\diseases of oral mucosa 2\diseases of orofacial region 3\salivary gland diseases 4/orofacial pain and TMJ dysfunction

  5. ORAL MUCOSA The oral mucosa is the mucous membrane lining the inside of the mouth

  6. ORAL MUCOSA Composed of two layers: 1\lamina propria 2\epithelium

  7. SALIVARY GLANDS SALIVARY GLAND: Group of glands that secretes saliva into oral cavity CLASSIFICATION: 1\MAJOR SALIVARY GLANDS (parotid-sub mandibular-sub lingual) 2\MINOR SALIVARY GLANDS (all over the oral cavity)

  8. TMJ(temporomandibular joint) TMJ: It is the joint of the jaw

  9. What we study in oral medicine 1\diagnostic skills 2\common laboratory diagnostic tests 3\therapeutics in oral medicine 4\oral and Para oral diseases (infections-nutritional diseases-endocrine disorders-dermatological diseases-salivary gland diseases-potentially malignant lesions-gastro intestinal diseases-TMJ disorders

  10. What is oral diagnosis Oral diagnosis is that branch of dentistry dealing with the identification of oral disease whether of local or systemic origin

  11. differential definitive

  12. DIAGNOSIS OF SOFT TISSUE LESION: Description of soft tissue lesion 1\site 2\color 3\morphology 4\size

  13. 1\SITE 1 4 3 2 7 5 6 8 9 11 10 12

  14. 1-upper lip 2-lower lip 3-retromolar pad 4-buccal mucosa 5-buccal vestibule 6-gingiva 7-hard palate 8-soft palate 9-uvula 10-tongue(lateral border) 11-tongue (ventral surface) 12-lingual mucosa

  15. 2\COLOR Normal mucosa ….pale pink to dark pink Mucosal lesions … 1\ red lesion (erythroplakia) 2\white lesion (leukoplakia) 3\pigmentations

  16. EXOGENOUS ENDOGENOUS ORAL PIGMINTATIONS

  17. 3\MORPHOLOGY Lesion Elevated Flat Depressed blistiform Non blistiform 1-Macule 2-patch ulcer scar .

  18. NON-BLISTIFORM(NOT FILLED WITH FLUID BLISTIFORM(FILLED WITH FLUID) A\Elevated lesions Vesicle <5 mm Bulla > 5mm Pustule (filled with pus) Papule <5mm Nodule >5mm Tumor >2 cm plaque

  19. .

  20. B\DEPRESSED LESIONS Ulcers Scars

  21. C\FLAT LESION 1\Macule 2\patch

  22. IMPORTANT TERMINOLOGY Ulceration vs. erosion Sessile vs. pedunculated Smooth versus rough Keratosis Verrucusand verrucoid Sinus and fistula

  23. Ulceration VS Erosion Ulcer is deeper than erosion

  24. Sessile Pedunculated PEDUNCULATED VS. SESSILE If the lesion is attached to the surface by a narrow stalk it is said to be pedunculated If the lesion is directly attached to the surface without stalk it is said to be sessile

  25. SMOOTH VS. ROUPH

  26. KERATOSIS Growth of keratinized tissues in the skin or mucous membranes

  27. Verrucus Covered with warts or wart like projections

  28. FISTULA SINUS SINUS AND FISTULA It is abnormal channel that ends in in one opening It is abnormal pathway between two anatomic spaces space
