Gingival Abscess Flashcards
What’s Gingival Abscess, sources and cp?
localized, acute inflammatory lesion involving marginal gingiva or inder dental papilla.
The lesion may arise from a variety of sources including :
1- Microbial plaque infection
2- Trauma
3- Foreign body impaction
Clinical features :
Appear as a red, smooth, shiny surface, sometimes painful, fluctuant swelling.
What’s Periodontal Abscess? Where is it found?
An acute exacerbation of a preexisting pocket,result from exudate and purulent material being entrapped in the pocket with no pathway for drainage .
1-Found in patients with untreated periodontitis, and in association with moderate to deep periodontal pockets. 2-Primarily related to incomplete calculus removal . 3- Tooth perforation or fracture .
4-Poorly controlled diabetes mellitus has been considered a predisposing factor for periodontal abscess formation.
C.p of acute Periodontal Abscess?
Clinical features (Acute pd.abscess) 1-painful
2- edematous, red, shiny ovoid elevation of marginal, attach gingiva or both
3- Fever appearance, elevation in temperature , and tendency to malaise.
Acute abscess may progress to chronic abscess if purulence content drains or exudate through fistula or sulcus
Differentiate Periodontal Abscess Vs Pulpal Abscess
Differentiate Acute abscess vs chronic abscess
What’s treatment of gingival abbess
1- Local anesthesia.
- -Incise fluctuant area (15 blade)& gently widen the incision for drainage.
- Area cleaned with warm water & covered with gauze. 4- After bleeding stops, pt. dismissed within 24 hr with instruction (every 2 hr rinsing with a glass full of warm water).
What are Treatment options (Periodontal abscess)?
A- Drainage through pocket retraction or incision from outer surface B- Scaling & Root
planing C- Periodontal
surgery
D- Systemic antibiotics 1- Acute Abscess
What’s purposes of treatment of acute abscess
The purposes of treatment are to :
1- Alleviate symptoms.
2- Control spread of infection.
3- Establish drainage.
● Before treatment, the patient’s medical history, dental history and systemic condition are reviewd.
What’s procedure of
Drainage through periodontal pocket retraction:
1- Anesthetize the area topically or by local anesthesia (which injected around periphery of lesion).
- -A flat instrument or probe is inserted to the pocket to distend pocket wall for drainage ,and curette can be inserted into pocket for further drainage and curration of the tissue internally .
- Gentle digital pressure & irrigation to express
exudates. 4- Small lesion, scaling & root planing for debridement.
- Gentle digital pressure & irrigation to express
5- large lesion, root debridement by scaling and polishing
What’s the procedures for B-Drainage through external incision:
- Isolate & dry area with gause sponges. After topical anas., application ,local anesthesia is injected around periphery of abs.
- Vertical incision was made through the most fluctuant part of the abscess (no. 15 blade)extending into area just apical to the abscess.
- Tissue elevated by curette or periosteal elevator to drain & curette gran. tissue internally
- Externally, push the abscess to drain remaining purulent material, and approximate wound edges.
- After drainage stops, the area is dried and paint with
antiseptic. 6- No suturing. - Instruct patient to rinse with ( 1 tsp of salt in glass of water), in addition to prescription ofantibiotics and analgesic, bed rest, avoid exertion, placed on a copious fluid and return for follow up evaluation for the next day
- Next day, reduced swelling & symptoms subside.
What are Indications for antibiotic therapy in acute abscess:
1- Cellulitis (non localized, spreading
infection).
2- Deep inaccessible pocket.
- Fever
- Regional lymphadenopathy.
- Immunocompromised patient
Antibiotic options for periodontal infections:
- -Amoxicillin,
- 1.0 g loading dose, then 500 mg three times a day for 3 days.
- Reevaluation after 3 days to determine need for continued or adjusted antibiotic therapy. Penicillin allergy: - -Clindamycin
- 600 mg loading dose, then 300 mg four times a day for 3 days.
3- Azithromycin (or clarithromycin)
- 1.0 g loading dose, then 500 mg four times a day for 3 days.
What’s procidure for chronic abscess
When acute pd .absc. Become chronic,the treatment is by
flap.
- Probing around gum following tortuous pocket.
- Local anesthesia & removal of supragingival
calculus. 3- Two vertical incisions made from gum to beyond MGJ. 4- Operating field wide enough. - Mesiodistal incision across interdental papilla for detachment of flap.
- Full thickness flap elevated with periosteal elevator. 7- Scaling & root planing.
- Pathological marginal bone is removed & antibiotics may be prescribed.
What are post surgical instructions
- No rinsing until next day.
- Mouth gently brushed with soft tooth brush and water irrigation.
- Patient returns back after a week to remove suture and pack.
- Plaque control.
- After 6-8 weeks, gingiva returns to normal. Bone repair needs 9 months.
