Title: ALWAYS LOOK FOR THE POSTIVE


1
ALWAYS LOOK FOR THE POSTIVE
  • When it is dark enough, you can see the stars.
  • -Persian proverb

2
Diseases of Digestive System
  • Chapter 2

Oral Diseases Periodontal Disease
  • Periodontal Disease is plaque-induced
    inflammation of gums
  • Progressive
  • Includes gingivitis, gingival hyperplasia,
    peridontitis with vertical bone destruction, and
    peridontitis with horizontal bone destruction
  • The end result is loss of tooth
  • Periodontal means around the tooth
  • Etiology
  • Food particles, bacteria collect around gum line
    and form plaque (tartar)
  • Causes gingivits
  • Minerals in saliva collect in plaque and harden
    to form calculus which adheres to teeth
  • 3-5 d to harden
  • Causes bad breath
  • Protects the bacterial environment

4
Oral Diseases Gingivitis
  • Gingivitisearliest signs of Periodontal Disease
  • Involves only the soft tissues of the gums
  • Reversible inflammation of gums
  • Gingival hyperplasia (may also be breed- or
    drug-related)
  • Causeaccumulation of tartar on teeth
  • Tartar is conducive to bacterial growth
  • Enzymes produced by bacteria damage tooth
    attachment and cause inflammation

5
Oral Diseases Periodontal Disease
  • Without intervention, gingivitis progresses to
  • Periodontitisirreversible condition
  • Loss of gingival root attachment (receding gums)
  • Alveolar bone resorption
  • Loss of teeth

7
Oral Diseases Periodontal Disease
  • Calculus builds up under gums
  • Separates teeth from gums to form pockets,
    which encourages more bacteria to accumulate and
    grow
  • Bacteria secrete toxins/enzymes that cause
    detachment of tooth from bony socket
  • WBCs invade area and release their enzymes to
    destroy bacteria
  • These enzymes also cause detachment of tooth from
    bone
  • Pockets get deeper and deeper
  • Weakens bone
  • Can cause pathologic fractures
  • Other sequellae
  • Bacteria enter blood stream
  • Can cause micro-abscesses in liver, kidneys
  • Cause endocarditis on heart valves

9
Oral Diseases Periodontal Disease
  • Signs
  • Halitosis
  • Reluctance to chew hard food
  • Pawing at mouth
  • Oral pain personality changes
  • Sneezing nasal discharge
  • Increased salivation
  • Facial swelling tooth loss
  • Dx
  • Complete oral exam
  • Presence of tartar (plaque) on teeth

10
Oral Diseases Periodontal Disease
  • Rx
  • Dental scaling
  • with ultrasonic scaler
  • Root scaling/planing (below gum line)
  • with thin ultrasonic tip curette
  • Gingival curettage
  • with curette against inner surface of gums
    (gingival pockets diseased soft tissue inner
    surface)
  • rationale is to convert chronically inflamed
    ulcerated lesions into a clean surgical wound to
    promote healing
  • Polishing to smooth the tooth surface and prevent
    tartar buildup
  • Irrigation to remove diseased tissue and plaque

Oral Diseases Periodontal Disease
  • Client info
  • Good oral hygiene is necessary for all pets
  • Brush teeth daily
  • Routine dental cleanings performed at
    veterinarians
  • Treat gingivitis early before irreversible
    lesions occur
  • Extractions are sometimes necessary to clear up
    infections
  • Hard, crunchy food may promote better dental
    health by removing tartar before it calcifies
  • Once it calcifies, tartar must be removed
    professionally

Oral Trauma
  • Causes (many)
  • Falls, fights (bites), burns, blunt trauma (HBC)
  • High-rise syndrome in cats
  • Fractured hard palate, mandible
  • Tongue injury from biting own tongue, dog fight,
    eat from tin can in garbage, FB(Foreign body)
  • Cats playing with needles, thread strangulate
    tongue
  • Electrical, chemical burns
  • Gunshot wounds, fish hooks
  • Bones lodged in teeth

15
Oral Trauma
  • Signs
  • History or signs of head trauma
  • Increased salivation
  • Inability to close mouth due to
  • Pain
  • Fracture/dislocation
  • FB
  • Reluctance to eat (same reasons)
  • Presence of foreign object
  • Dx
  • PE of oral cavity
  • X-ray to r/o embedded FB

16
Oral Trauma
  • Rx
  • Depends on type of trauma
  • Control bleeding
  • Provide supportive care
  • IV fluids
  • pain relief
  • Insure adequate airway
  • Repair/extract damaged teeth
  • Client info
  • Like kids, if animals can get into trouble, they
    will
  • Discourage chewing on electric cords
  • Dont leave caustic/toxic chemicals out
  • Keep pets in fenced yard or on leash when outside
  • Animals still eat well without entire tongue

17
Oral Neoplasia
  • Relatively common in cats and dogs malignant
    melanoma and squamous cell carcinoma most common
  • Signs
  • Depend on location and size of growth
  • More common in males
  • Abnormal food prehension
  • Increased salivation
  • Tooth loss
  • Oral pain
  • Dx
  • Histology of mass
  • X-rays to r/o metastasis
  • Biopsy of LN to r/o metastasis

Squamous cell carcinoma (Upper R 3rd
incisor) Bone loss around lesion Rostral
maxillectomy was curative

joint region.

19
Oral Neoplasia
  • Rx
  • Surgical excision
  • Partial removal of mandible/maxilla if bone is
    involved
  • Radiation therapy
  • Chemotherapy
  • Client info
  • Px for malignant tumors is guarded even with
    aggressive therapy
  • Benign lesions have good Px
  • Animals (esp cats) with bone removed may need
    nutritional support (feeding tube)

Salivary Mucocele
  • Accumulation of excessive amounts of saliva in SQ
    tissue
  • Most common lesion of salivary glands in dogs
    rarely seen in cats (following trauma)
  • Cause is unknown (tight collar, choke chain??)
  • Signs
  • Slowly enlarging, nonpainful, fluid-filled
    swelling on neck or under tongue
  • Reluctance to eat
  • Difficult swallowing
  • Blood-tinged saliva
  • Respiratory distress

22
Salivary Mucocele
  • Dx
  • Clinical signs
  • Paracentesis shows thick, blood-tinged fluid
  • Rx
  • Aspirate fluid
  • Surgical drainage
  • Remove salivary gland insert Penrose drain x 7 d
  • Client info
  • Cause is unknown trauma may be involved
  • Without removal of gland, excess fluid will
    continue to accumulate
  • Some cases may resolve spontaneously

23
Lip-Fold Dermatitis
  • Often seen in breed with pendulous upper lips
    (spaniels, setters, St. Bernard, bulldogs,
    bassets)
  • Constant moisture in the folds from saliva causes
    bacterial growth
  • Food, hair, moisture cause irritation, erythema,
    and fetid odor
  • Signs
  • Halitosis
  • Collection of debris in lower lip fold
  • Dx
  • Clinical signs
  • Rx
  • Dental cleaning
  • Clip hair
  • Clean out folds (food)
  • Diaper rash cream
  • Sx is permanent Rx

24
Lip-Fold Dermatitis
  • Client info
  • Keep lip folds dry (for the rest of animals
    life!!)
  • Flush/clean lip folds
  • with 2.5 benzoyl peroxide shampoo
  • chlorhexidine
  • malaseb pledgets (chlorhexidine miconazole)
  • Drying agents like corn starch several times a
    day
  • Good dental hygiene will help prevent it
