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
. Dentist and dental hygienist can make preliminary diagnosis of systemic disease because many systemic disorders have oral manifestations
FIELDS OF ORALMEDICINE 1\diseases of oral mucosa 2\diseases of orofacial region 3\salivary gland diseases 4/orofacial pain and TMJ dysfunction
ORAL MUCOSA The oral mucosa is the mucous membrane lining the inside of the mouth
ORAL MUCOSA Composed of two layers: 1\lamina propria 2\epithelium
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)
TMJ(temporomandibular joint) TMJ: It is the joint of the jaw
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
What is oral diagnosis Oral diagnosis is that branch of dentistry dealing with the identification of oral disease whether of local or systemic origin
differential definitive
DIAGNOSIS OF SOFT TISSUE LESION: Description of soft tissue lesion 1\site 2\color 3\morphology 4\size
1\SITE 1 4 3 2 7 5 6 8 9 11 10 12
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
2\COLOR Normal mucosa ….pale pink to dark pink Mucosal lesions … 1\ red lesion (erythroplakia) 2\white lesion (leukoplakia) 3\pigmentations
EXOGENOUS ENDOGENOUS ORAL PIGMINTATIONS
3\MORPHOLOGY Lesion Elevated Flat Depressed blistiform Non blistiform 1-Macule 2-patch ulcer scar .
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
B\DEPRESSED LESIONS Ulcers Scars
C\FLAT LESION 1\Macule 2\patch
IMPORTANT TERMINOLOGY Ulceration vs. erosion Sessile vs. pedunculated Smooth versus rough Keratosis Verrucusand verrucoid Sinus and fistula
Ulceration VS Erosion Ulcer is deeper than erosion
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
KERATOSIS Growth of keratinized tissues in the skin or mucous membranes
Verrucus Covered with warts or wart like projections
FISTULA SINUS SINUS AND FISTULA It is abnormal channel that ends in in one opening It is abnormal pathway between two anatomic spaces space
