Chapter 7 Flashcards
What is periodontitis?
Complex microbial infection that triggers a hot-mediated inflammatory response within the periodontium
What does periodontitis result in?
The destruction of the PDL and alveolar bone. Also affects the gingiva and cementum
What is periodontitis a result of the action between?
Plaque biofilm and the hosts immune response
Is clinical appearance a reliable indicator of the presence or severity of chronic periodontitis?
No. Chronic disease may present with less bleeding or visible inflammation. Some signs and symptoms can be indicative of conditions other than periodontitis. Differential diagnosis needed.
Probing and radiographs needed
What are some symptoms of perio that may be related to other issues?
Red, swollen gingiva- severe gingivitis
Bleeding from brushing- gingivitis
Bad taste in mouth- medication
Bad breath- diet, tongue coating
Sensitivity- recession, traumatic brushing
Pus- endodontic origin
What is the etiology of periodontitis?
Bacterial plaque and calculus
Characteristics of clinical attachment loss
Apical migration of JE
Destruction of gingival and PDL fibers
Loss of AB
Possible furcation involvement
Tooth mobility/migration
Factors contributing to periodontitis
Smoking
Diabetes
HIV status
Genetics
Local factors: crowding/malposition
Overhanging restoration margins
Symptoms that may be reported by the patient
Bleeding gums
Spaces developing btw their teeth
Loose teeth
Increased food impaction or tooth sensitivity
Pain- only with acute exacerbations of disease
What is an abscess?
Acute infection involving a circumscribed accumulation of pus within the gingival wall of the periodontal pocket
What is pus or exudate?
Whitish-yellow, consisting of dead and dying neutrophils, bacteria, cellular debris, and fluid from BV
How are acute abscesses characterized?
Rapid onset
Constant and localized pain
Usually an exacerbation of a chronic inflammatory periodontal lesion
How are chronic abscesses characterized?
Grows slowly, usually asymptomatic because of drainage through sinus tract
Typically painless but may cause dull pain
Characteristics of periodontal abscesses
May be chronic or acute
Localized swelling in periodontium
Possible increase in mobility
Radiographic bone loss, not involving tooth apex
Tooth usually vital
Possible elevated temp
May release pus through sinus tract
Causes of periodontal abscess
Blockage of the orifice of a pocket
Accidental introduction of a foreign object into the pocket: popcorn husk
Incomplete calculus removal
