Non-Plaque Induced Inflammatory Gingival Lesions Flashcards
T/F: Gingival inflammation, clinically presenting as gingivitis, is always due to accumulation of plaque on tooth surface
FALSE
its not always caused by plaque (but plaque is always present according to the previous lecture)
what types of gingival lesions are not caused by plaque accumulation? (theres 6 types)
1) Gingival lesions of VIRAL origin
2) Gingival lesions of FUNGAL origin
3) Gingival lesions of GENETIC origin
4) Gingival lesions of SYSTEMIC origin
5) TRAUMATIC lesions
6) Gingival lesions of specific bacterial origin
what gingival conditions are caused by specific bacteria?
Infective gingivitis and stomatitis
what are the clinical presentations of periodontitis caused by specific bacteria?
Fiery red edematous painful ulcerations
Asymptomatic chancres
Mucous patches
Atypical non-ulcerated, highly inflamed gingivitis
how is gingivitis (thats caused by specific bacterial species) diagnosed?
Biopsy
Microbiologic examination
what type of gingivitis is caused by the various herpes viruses? when are they most likely seen?
Acute herpetic gingivostomatitis
most frequently seen in infants and children younger than 6 yrs
what are the first clinical signs of acute hepatic gingivostomatitis?
Initially, it is characterized by the presence of discrete, spherical gray vesicles which may occur on the gingiva
within 24 hours, what happens to the spherical vesicles associated with acute hepatic gingivostomatitis?
vesicles rupture and form painfull small ulcers with a red, elevated, halo-like margin and a depressed yellowish or grayish white central portion
symptoms of Primary herpetic gingivostomatitis
- painful severe gingivitis with redness
- ulcerations with serofibrinous exudate
- edema accompanied by stomatitis
what are the characteristics of Primary herpetic gingivostomatitis
- Incubation period is one week.
- Formation of vesicles, which rupture, coalesce
and leave fibrin-coated ulcers. - Healing within 10 to 14 days.
________ is found in gingivitis, Necrotizing Ulcerative Diseases (NUG/NUP) and periodontitis
the herpes virus
T/F: More primary herpes infections occur at older ages in industrialized society
true
Primary herpetic gingivostomatitis may be asymptomatic in childhood, but may also give rise to ____________
severe gingivostomatitis
what is a characteristic manifestation of recurrent intraoral herpes infections?
a cluster of small painful ulcers in the attached gingiva and hard palate
Recurrent ______ infections occur, in general, more than once a year
herpes
Herpes Labialis
what are the characteristic of an infection from the Virocella-zoster virus?
- Small ulcers usually on the tongue, palatal and gingiva.
- Latent in the dorsal root ganglion.
- Unilateral lesions.
- 2nd and 3rd branch of the trigeminal ganglion
the diagnosis for _______ is usually obvious due to theunilateral occurrence of lesions associated with severe pain
Virocella-zoster virus
what are the 3 fungal infections that are most likely to effect the oral cavity?
Candidosis
Linear gingival erythema
Histoplasmosis
T/F: the fungus C.albicans is not found in the mouths of healthy patients
FALSE
found in 3-48% of healthy adults
what groups are at risk for Candidosis?
people with a reduced host defense (immunosuppressed individuals, infant and adult who has been on antibiotic therapy for some time)
________ is frequently isolated from the subgingival flora of patients with severe periodontitis
C.albicans
what are the clinical characteristics of candidosis?
Painless or slightly sensitive
Red and white lesions
Lesions can be scraped or separated from mucosa
how can candidosis be diagnosed?
A culture on Nickersons medium at room temp.
Microscopic examination of a smear of the material
scraped from the lesion and stained.
T/F: In otherwise healthy patients, oral candidosis rarely manifests in the gingiva
true
