Title: Applied Oral Pathology through Interactive Learning


1
Applied Oral Pathology through Interactive
Learning
  • Infectious Diseases
  • Rachel S. Ennis
  • MDH707 Spring 2011

2
Infectious DiseasesChapter 4 Objectives
  • Inflammatory and immune response
  • Causes of opportunistic infection
  • Organisms involved in specific infectious
    diseases
  • Oral candidiasis five forms
  • Herpes labialis clinical features
  • Recurrent intraoral herpes simplex infection
    clinical features
  • Minor aphthous ulcers clinical features

3
Objectives continued
  • Herpes Zoster clinical characteristics
  • Epstein-Barr Virus four associated diseases
  • Coxsackie virus and oral manifestations
  • Oral manifestations of HIV infection clinical
    appearance

5
Acute Necrotizing Ulcerative Gingivitis
  • Edematous and erythematous gingiva
  • Cratered or punched out
  • interdental papillae
  • Painful
  • Foul odor
  • Metallic Taste
  • Associated with decreased resistance
  • Caused by Fusiform bacilli,
  • and spirochetes

6
Inflammatory and Immune Response
  • Inflammatory response bodys first line of
    defense against tissue injury and
    disease-producing microorganisms
  • Immune response defends body against injury,
    remembers past instances of injury

7
Opportunistic Infection
  • Alteration in the oral micro flora
  • Organisms that are normally nonpathogenic are
    able to cause disease

8
Opportunistic infections of the oral cavity
  • Dental caries
  • Periodontal disease

9
Infectious Diseases and the organisms involved
  • Impetigo Staph Aureus, Staph pyogenes.
  • Tonsillitis and Pharyngitis Streptococci,
    Adenoviruses, Influenza, and Epstein-Barr virus
  • Tuberculosis Mycobacterium tuberculosis
  • Actinomycosis Actinomyces israelii
  • Syphilis Treponima pallidum
  • Veruca vulgaris Human papilloma virus
  • Condyloma acuminatum Human papilloma virus
  • Primary herpetic gingivostomatitis Herpes
    simplex virus
  • Acute Necrotizing Ulcerative Gingivitis
    Borrelia vincentii fusiform bacillus, and
    spirochete

10
Impetigo
  • Adult male with impetigo
    Child with impetigo on chin
  • on chin

11
Syphilis chancre
  • Dorsal surface of tongue

12
Actinomycosis
  • Left mandible

13
Condyloma acuminatum
  • Lower lip

14
Oral Candidiasis(thrush)
  • Pseudomembranous
  • Erythematous
  • Denture stomatitis (chronic atrophic candidiasis)
  • Chronic hyperplastic candidiasis
  • Angular cheilitis

15
Angular cheilitis
  • Commissure of lips

16
Pseudomembranous candidiasis
  • Hard palate

17
Herpes Labialis
  • Caused by herpes simplex virus
  • Also called cold sore or fever blister
  • Vermillion of lips

18
Herpes Labialis
  • Vesicles on lips and vermillion boarder

19
Herpes Labialis
  • Lower lip

20
Recurrent intraoral herpes simplex infection
  • Herpes simplex virus
  • Keratinized mucosa (hard palate, and gingiva
  • May be caused by sunlight,
  • menstruation,fatigue,fever,stress
  • Painful, focal crops of vesicles
  • Prodromal symptoms pain,burning,tingling

21
Primary Herpes Simplex Infection
  • Dorsal surface of tongue

22
Minor aphthous ulcers
  • Nonkeratinized mucosa
  • One to several ulcers present
  • No vesicle preceding ulcer
  • Pain
  • lt1cm
  • Round to oval
  • Can recur

23
Minor aphthous ulcer
  • Floor of mouth

24
Major Aphthous Ulcer
  • Soft palate

25
Herpes Zoster
  • Shingles
  • Unilateral, painful eruption of vesicles along
    sensory nerve
  • May affect three branches of trigeminal nerve
  • Prodromal symptoms pain, burning,paresthesia
  • May last several weeks

26
Herpes Zoster
  • Shingles

27
Varicella Zoster
  • Lips and palate

28
Epstein-Barr Virus
  • Infectious Mononucleosis
  • Palatal petichiae
  • kissing disease
  • Nasopharyngeal carcinoma
  • Burkitt lympoma
  • Hairy Leukoplakia
  • usually on lateral border of tongue

29
Hairy Leukoplakia
  • Lateral boarder of tongue

30
Coxsackievirus
  • Discovered in Coxsackie, NY
  • Transmission by fecal-oral contamination, saliva,
    respiratory droplets
  • May cause
  • Herpangina
  • Hand-Foot-and Mouth Disease
  • Acute Lymphonodular Pharyngitis

31
Coxsackie virus
  • Sores on dorsal surface of tongue and palate

32
HIV and Oral Lesions

  • Non-Hodgkin lymphoma
  • Aphthous ulcers
  • Mucosal pigmentation
  • Bacterial salivary gland enlargement and
    xerostomia
  • Spontaneous gingival bleeding resulting from
    thrombocytopenia

33
