Lesson 2.4: Oral Conditions and Injuries Flashcards
What is oral pathology
The study of diseases that affect the mouth
Inflammation of the gingiva
Gingivitis
Signs and symptoms of plaque-induced gingivitis
- Swelling (edema)
- Redness
- Increased heat
- Loss of stippled appearance
- Bleeding
- Occasional pain
Causes of plaque-induced gingivitis
Plaque and calculus formation due to:
- Improper brushing
- Flossing
- Mouth breathing
Characteristics of plaque-induced gingivitis
- Gingiva appears shiny due to the added fluid
2. Bright red from increased blood flow due to the swelling of the gingival margin
Treatment of plaque-induced gingivitis
Completely remove the supragingival and subgingival irritants through oral prophylaxis (teeth cleaning) and oral hygiene instructions
Types of Hormonal-influenced Gingival Disease
- Puberty-associated gingivitis
- Pregnancy-associated gingivitis
- Menstrual cycle gingivitis
Characteristics of Hormonal-influenced Gingival Disease
Gingiva having an exaggerated response to plaque, reflected by:
- Intense inflammation
- Redness
- Edema
- Enlargement of the gingiva with no bone loss at the time
This is also known as “Trenchmouth” or “Vincent’s Disease”
Necrotizing Ulcerative Gingivitis (NUG)
A bacterial infection where the tissue of the interdental papilla is dead or dying
Necrotizing Ulcerative Gingivitis (NUG)
This name came into effect in WWI when soldiers who were down fox holes and trenches didn’t have access to basic oral hygiene aids to take care of their teeth, causing disease.
Trenchmouth
Causes of Necrotizing Ulcerative Gingivitis
- Prolonged poor oral hygiene
- Poor nutrition
- Fatigue
- Emotional Stress
Characteristics of Necrotizing Ulcerative Gingivitis
- Malaise
- Severe bad breath
- Gray or yellow-gray ulcers
- Difficult brushing or chewing
- Highly inflamed gingiva that bleeds easily
- Fever
An indefinite feeling of debility or lack of health often indicated of or accompanying the onset of an illness
Malaise
Treatment of Necrotizing Ulcerative Gingivitis
- Reassure the patient
- Doctor may also prescribe antibiotics within 24 to 48 hours
- Gentle debridement (removing the worst of the plaque and calculus) once acute inflammation has subsided
- A mouth rinse, such as Chlorhexidine
- Proper rest, diet, and exercise
- Elimination of smoking, carbonated drinks, and alcoholic beverages advised
- Home care instructions are given and the patient re-appointed a follow-up
Cause of Drug-influenced Gingival Enlargement
Result from systemic drug use (a systemic drug affects a specific system of the body)
Mouth-breathing and heredity can aggravate this condition
Drug-influenced Gingival Enlargement
Characteristics of Drug-influenced Gingival Enlargement
Gingiva that looks fibrous, but there is no redness or pain present
Treatment of Drug-influenced Gingival Enlargement
Surgical excision of the extra tissues
Who is able to surgically excise extra tissue caused by Drug-influenced Gingival Enlargement
A dentist
Inflammation of the gingiva that involves the crest of the alveolar bone and the periodontal ligament above the alveolar crest
Periodontitis
Cause of Periodontitis
Untreated marginal gingivitis
Inflammation of the gingiva around a partially erupted tooth; pathogens and plaque get underneath the flap causing an infection
Pericoronitis
Pericoronitis usually affects which tooth
Mandibular third molars
Also known as dry socket
Post-extraction Alveolar Osteitis
Occurs when a blood clot fails to form or washes out of the socket from a recently extracted tooth
Post-extraction Alveolar Osteitis
Treatment of Post-extraction Alveolar Osteitis
- Gently rinse the socket with warm saline solution
2. Moisten a small strip of iodoform gauze with eugenol and loosely pack socket
A condition associated with the overgrowth of bone
Tori
TRUE OR FALSE:
Herpes Simplex Virus is highly contagious
True
Causes of outbreaks in Herpes Simplex Virus
- Stress
- Fever
- Illness
- Injury
- Exposure to sunlight
Type of Herpes Simplex Virus associated with fever blisters or cold sores
HSV 1
TRUE OR FALSE: Herpes Simplex Virus (HSV) 1 can be transferred to genitals
True
Length of time it takes Herpes Simplex Virus (HSV) 1 to heal
7-14 days
This type of Herpes Simplex Virus is most commonly found on genitals
HSV 2
This type of Herpes Simplex Virus is most commonly contracted through sexual contact
HSV2
TRUE OR FALSE:
Aphthous Ulcers/Canker Sores are contagious
False
Causes of Aphthous Ulcers/Canker Sores
- Trauma
- Infection
- Auto-immune diseases
Length of time it takes Aphthous Ulcers/Canker Sores to heal
7-10 days
This is caused by the irritation of oral mucosa
Leukoplakia
Type of Leukoplakia most commonly caused by the use of smokeless tobacco products
Precancerous Leukoplakia
Type of Leukoplakia most commonly associated with HIV/AIDS
Hairy Leukoplakia
Bacteria waste products and food debris combine to form a sticky substance. This is known as
Plaque
Causes of Tooth Decay (Caries)
- Activity of bacteria and acids in dental plaque
- Poor oral hygiene
- Diet high in sugar intake
- Plaque buildup in sheltered areas between the teeth (mesial and distal)
- Defects in the teeth
Three factors that determine the destructive progression of Tooth Decay (Caries)
- Oral Hygiene
- Diet
- Resistance of the tooth surface to acid
Effect of Tooth Decay (Caries)
Pain from local irritants or decay approaching the pulp
How may Tooth Decay (Caries) appear on dental radiographic/images
Radiolucent or black
Treatment of Tooth Decay (Caries)
Completely remove the decay (caries) and replace it with a restoration
Treatment of Tooth Decay (Caries) that have not gone beyond the enamel layer tooth
May be able to be treated with mouth rinses and fluoride.
Tooth Decay (Caries) that have not gone beyond the enamel layer tooth is referred to as
Incipient Caries
Inflammation of the pulp
Pulpitis
Causes of Pulpitis
- Physical - deep carious lesions that penetrated into the pulp; physical trauma (blow to the tooth or improper occlusion)
- Thermal - Excessive heat during cavity preparation
- Chemical - irritating medications or restorative materials being placed near the pulp
The initial response of the pulp to shock or irritation
Hyperemia
Hyperemia increases the blood in small arteries of the pulp, increasing pressure on the nerves and producing pain, which can cause
Pulpitis
Types of pulpitis
- Reversible Pulpitis
2. Irreversible Pulpitis
The temporary irritation where the pulp usually heals itself once the cause of the irritation has been removed
Reversible Pulpitis
A condition where the pulp cannot heal itself
Irreversible Pulpitis
A tooth with pulpitis will have what kind of sensitivities
- Hot
- Cold
- Percussion
Treatment of Reversible Pulpitis
The removal of irritants
Treatment of Irreversible Pulpitis
Endodontic Therapy (root canal). As a last resort, the tooth may be extracted
Type of therapy that consists of opening the tooth from the occlusal surface to remove the infected pulp tissue
Endodontic Therapy (root canal)
Localized collections of pus formed by bone and or soft tissue destruction
Abscesses
Type of Abscess around the apex of a tooth
Periapical Abscess
Type of Abscess formed in the gingival tissue
Periodontal (Gingival) Abscess
Causes of Periapical Abscesses
Traumatic injury or infection following pulpitis of the tooth
The two types of Periapical Abscesses
- Acute
2. Chronic
Treatment of Periapical Abscesses
- Endodontic Therapy (root canal)
- Incision and drainage procedure where a hole in the abscess is drained of the pus
- Antibiotics to stop the infection along with pain-relieving drug/agents
If all treatment of Periapical Abscesses are unsuccessful, what may be necessary?
A tooth extraction
Causes of Periodontal (gingival) Abscesses
When inflammatory drainage from a periodontal pocket is blocked
The two types of Periodontal (gingival) Abscesses
- Acute
2. Chronic
Treatment of Periodontal (gingival) Abscesses
- Incision and drainage
- Scaling and curettage (clean the picket and tooth with dental instruments to remove the irritant)
- Antibiotics
If all treatment of Periodontal (gingival) Abscesses are unsuccessful, what may be necessary?
