Gingivosis, as described by Schour and Massler, was apparently a gingival manifestation of chronic and acute nutritional deficiency in children.
Most of cases of dg are seen in association with MMP, followed by olp pv & le According to different case series, MMP is responsible for ;35% to 48% of cases of DG. OLP and PV account for 24% to 45% and 3% to 15%19,23 of cases, respectively
Before going into the etiopthogenesis im going to discuss briefly about the epithelial biology which is relevant to the disease. A basic knowledge about the epithelial biology is necessary in order to understand the pathogenesis of dg. Among theses des, hemids and their structural proteins ply an important role in the pathogenesis of dg
Desmosomes contains proteins like desmogleins and desmocollins. Desmogleins are glycoproteins of the cadherin-supergene family which link to cytokeratins via desmoplakins and plakoglobin. Cadherins are a family of calcium-dependent cell to cell adhesion molecules that play important role in the formation and maintenance of complex tissue integrity. They are composed of an extracellular domain involved in calcium dependent binding to adjacent cells, a transmembrane and an intracellular domain that binds to catenins and thence to actin (Masayuki, 2010). There are four desmoglein isoforms, designated as Dsg1–4. Expression of desmoglein 1 and 3 is restricted to stratified squamous epithelia. Dsg 1 and 3 are both expressed in skin but in oral epithelium only the 130 KDA molecule Dsg 3 is preferentially expressed. The intraepithelial expression patterns of Dsg 1 and 3 in skin and mucous membranes differ. In the skin, Dsg 1 is expressed throughout the epidermis, but more intensely in the superficial layers, while Dsg 3 is expressed in the lower portion of the epidermis, primarily in the basal and parabasal layers.
The autoab formed against these ag will bind to them either intercellulary or at th ep.-ct interface resulting in the formation of Ag-ab complexes Activates complement, attracts immune cells etc.. Finally cause acantholysis/dissolution of ep-basal lamina junc. Leading to an inra or sub ep clefts
Glickman and Smulow have described three forms of desquamative gingivitis viz mild, moderate, and severe.
Pathogenesis: Current data suggest that OLP is a T cell-mediated autoimmune disease in which auto-cytotoxic CD8+ T cells trigger apoptosis of oral epithelial cells. However, the precise cause of OLP is unknown.
The two major antigenic determinants of bullous pemphigoid are: 230-kD protein plaque known as BP1 180-Kd collagen-like transmembrane protein BP2.
epidermal and mucous membrane blisters occur when the cell-to-cell adhesion structures are damaged by the action of circulating autoantibodies and by the in vivo binding of these autoantibodies to the pemphigus vulgaris antigens, which are cell-surface glycoproteins that are present in keratinocytes. (Fine JD. Et al N Engl J Med 1995.Korman NJ. Et al Dermatol Clin 1990 Eversole LR. Et al Oral Surg Oral Med Oral Pathol 1994 Calvanico NJ et al J Autoimmun 1991)
60% of patients with pemphigus vulgaris, the oral lesions are the first sign of the disease
Combination of Sulfones and Dapsone. Small amounts of Prednisone (10-30mg/day) can be added. Alternatively, tetracycline (2g/day) combined with nicotinamide (1-5g/day) have shown promising results.
An increase in the incidence of skin and oral manifestations of hypersensitivity to drugs has been noted since the advent of sulfonamides, barbiturates, and various antibiotics
A thorough clinical history is mandatory to begin the assessment of desquamative gingivitis. Data regarding the symptomatology associated with this condition as well as its historical aspects (i.e., when the lesion started, whether it has worsened, if there is a habit that exacerbates the condition) provide the foundation for a thorough examination. Information regarding previous therapy to alleviate the condition should also be documented.
HPA axis suppression resulting in reduced cortisol response may cause an impaired stress response and an inadequate host defence against infections, which remains a cause of morbidity and death.
a 25 yr old female pt diagnosed with erosive lp presenting dg was tx with fgg and corticosteroids Although recurrence of the lesions was observed following both treatment modalities, free gingival graft despite being an aggressive therapy, proved more effective and with fewer side effects compared with topical or systemic steroid therapy, and seems to be a promising treatment modality with the benefit of more stable results, among others.

Degree of suppression is dependent on drugs used, dose, duration of administration, time elapsed since steroid therapy was terminated & route of admins.

Diagnosis of Desquamative
Gingivitis: A Systematic
Periodontal therapy involves not only the tx of plaque induced diseases
but also varous nonplq induced conditions. And one of those conditions
is desquamative gingivitis.
Periodontal therapy involves not only the diagnosis and treatment of
plaque associated diseases but also various non plaque related diseases.
The International workshop for classification of periodontal diseases
and conditions noted that the periodontist may be called upon to
manage these non-plaque related mucocutaneous disorders either
alone or as a part of treatment team consisting of physicians, dentists or
other allied health care professionals. Among the oral manifestations
which have long baffled dentists, chronic desquamative gingivitis is one
of the most interesting and persistent

the skin or mucosa.
• “A peculiar condition characterized by intense erythema,
desquamation, and ulceration of the free and attached gingiva.”

response associated with a variety of conditions.”

Hosiosky, et al, 1961: suggested treatment of
DG by improving cervical oral hygiene.
Glickman and Smulow, 1962: studied the
histopathology and histochemistry. Two basic
microscopic types recognized: a bullous type, and
a lichenoid type.
Glickman and Smulow, 1964: advocated a treatment
regimen of systemic corticosteroid therapy and
removal of local irritants.

For direct Immunoflourescence :
Unfixed frozen sections are incubated with a variety of
flourescein labelled anti - human serum (antiIgG, antiIgA,
anti IgM, anti- fibrin, anti- c3 etc.,)
Indirect Immunoflourescence :
Unfixed frozen section from oral or esophageal animal
mucosa are first incubated with the patients serum to allow
attachment of any serum antibodies to mucosa
After the diagnosis is established, the dentist must choose
the optimum management for the patient.
This is accomplished in accordance with three factors:

(2) the systemic impact of the disease;

In patients with suspicious desquamative lesions of the gingiva,
it is imperative to establish a definitive diagnosis via
histopathologic and immunologic findings.
The goal of treatment should focus on eradication of the lesions
prior to any periodontal therapy, following a conservative
These diseases may not be limited to the oral cavity, and it is
crucial that appropriate consultations are made to ensure
optimal patient care. The Periodontist has a unique opportunity
to make the diagnosis and then refer the patient to a medical
specialist for treatment.
Thus a thorough understanding of these conditions is necessary
so as to provide complete care to our patients .

some adrenal reserves after immediate termination of steroids.
