Q

What happens with incomplete calculus removal with a periodontal abscess?

A
  • Calculus removed from coronal aspect of deep pocket
  • calculus remains deep due to difficult access
  • Coronal tissue heals and tightens
  • Prevents drainage of toxins and waste: abscess formation

Q

What are the differential diagnosis for a periodontal abscess?

A
  • periocoronitis
  • endo-perio abscess
  • pyogenic granuloma
  • osteomylelitis
  • odontogenic keratocyst
  • Tumor lesion: metastic lesin, odontogenic myxomam non-hogkins lymphoma, squamous cell carcinoma
18
Q

What is the occurrence of periodontal abscess?

A
  • Obstruction
  • Inability to drain/formation of fistuka
  • Diabetics more susceptible
  • Acute condition
19
Q

What are the signs and symptoms of periodontal abscess?

A
  • Pain and pressure
  • Shiny mass
  • Deep probing depths
  • Mobility
  • Tender to percussion
  • Feels high
  • Purulence on pressure
  • Untreated or unresolved abscess
20
Q

What is the treatment for periodontal abscess?

A
  • First phase involves management of acute signs and symptoms: alleviate the pain, establish drainage, control spread
  • Second phase (treatment of underlying perio lesions, pocket elimination): Subgingival debridement, soft diet, analgesics, saline rinse, antibiotics only if systemic involvement, surgery if no resolution, follow up
21
Q

What are periapical abscess?

A
  • Results from infection and death of pulp by toxins (non- vital)
  • Trauma, caries or adjacent infected tooth
  • Usually a radiolucency at apex
22
Q

What are the different ways a periapical adbcess can drain?

A
  • Drain via sulcus or fistula
  • require endodontic treatment or extraction
23
Q

If a periapical abscess is left untreated then it can?

A
  • Lead to life threatening situations and death
24
Q

What are the differences between periodontal abscess and periapical abscess

A

Periodontal
⚫ Foreign object
⚫ Preexisting pocket
⚫ Lateral radiolucency
⚫ Vital tooth
⚫ Fistula at lateral aspect of tooth
⚫ Swelling in attached gingiva
⚫ Dull pain/constant
⚫ Mild percussion pain
⚫ Mobility
Periapical
⚫ Associated with decay/ large
restoration
⚫ Usually no pocket
⚫ Apical radiolucency
⚫ Nonvital tooth
⚫ Fistula in apical area
⚫ Swelling at MGJ
⚫ Severe pain/ throbbing
⚫ Intermittent pain
⚫ Severe percussion pain
⚫ No or minimal mobility

25
Q

What are endo-perio lesions?

A
  • most periodontal and endodontic lesions ( exist independently from each other)
  • Diagnostic challenge
26
Q

What are some old category problems?

A
  • Lesions may occur in subjects with or without periodontitis
  • ** “Combined” too generic and not sufficiently descriptive for
  • deciding treatment

Divisions
* Based on primary source of infection
* Relies on complete history
* Often unavailable to the clinician
* Treatment needs not relevant
* Both root canal and periodontal tissues require treatment

27
Q

What are the new category lesions?

A
  • Classified by signs and symptoms at presentation related to treatment:
    Presence or absence of fractures / perforations
    Presence or absence of periodontitis
    Extent of periodontal destruction
28
Q

What are signs of a endodontic lesion

A
  • Necrotic pulp
  • Chronic inflammation
  • Border of lesion wider at apex
  • Radiographs reveal isolated periodontal problem
  • Drainage- Sinus tract through sulcus ,Pathway through PDL from apex orlateral canal
29
Q

Communication through the apex or lateral canal can cause what because of drainage?

A

bifurcation involvement

30
Q

What are the treatment for endodontic lesions?

A
  • RCT and re-eval
  • Closure of tract and elimination of probing depth indicates successful treatment
  • Excellent prognosis
  • No root planing when sinus tractalong PDL
31
Q

Periodontal lesions can ?

A
  • Can sometimes mimic endodontic lesions
  • Observed on multiple teeth in generalized periodontitis
  • Border of lesion wider at gingival margin
  • Vital pulp
32
Q

Periodontal Lesions can lead to ?

A
  • Can lead to endodontic infection
    : Periodontal lesion at cervical margin and Lateral canal exposed to oral environment
33
Q

What are the main signs and symptoms for endo-perio lesions?

A
  • Deep periodontal pockets near apex AND
  • Negative or altered pulp vitality test
34
Q

What are some other signs and symp for a endo-perio lesion?

A
  • Bone resorption (apex or furcation)
  • Palpitation pain
  • Percussion pain
  • Exudate
  • Tooth mobility
  • Sinus tract
  • Gingival color change
35
Q

What are the causes of a endo period lesion?

A
  • Endodontic and/or periodontal infections
  • Trauma and/or iatrogenic (treatment) factors
36
Q

What are the main risk factors for endo perio lesion?

A
  • Advanced periodontitis*
  • Trauma
  • Iatrogenic events
37
Q

What are some other risk factors for endo-perio lesions?

A
  • Groove presence* Palatal most common with non-perio
  • furcation involvement*
  • PFM crowns
  • Active carious lesions
  • = presence often worsen prognosis
38
Q

What are the diagnosis and classifications for endo-perio lesion?

A

First Phase
* Patient history
* Identifies trauma occurrence and endodontics
* Clinical or radiographic exam
Second Phase
* Full-mouth periodontal assessment- PD, CAL, BOP, FG, MOD, etc
* Tooth vitality and percussion tests

39
Q

What are the treatment for periodontal lesions?

A
  • Periodontal therapy
  • RCT not indicated unless vitality changes
  • Periodic follow up to evaluate
  • Retrograde (comes back) endodontic problems
40
Q

Endodontic lesions respond well to conventional therapy like?

A

Debridement of pulp
Endodontic therapy

41
Q

Periodontal component more difficult to treat because?

A
  • Cannot resolve as long as endodontic lesion present
  • Does not resolve as predictably as endodontic lesion
  • The greater the periodontal involvement, the poorer the prognosis
