genital
What is this clinical presentation?

Pemphigus vulgaris
PV Lesions can affect
virtually any mucosal
surface (oral, nasal,
ocular, pharyngeal,
esophageal, genital)
What is this clinical presentation?

Pemphigus vulgaris
usually suffer from Desquamative
gingivitis (DG)
More superficial erosion of the marginal gingiva, typically with an
intense erythema and inflammation, and very often in the absence of
local factors that would typically cause a gingivitis
o Hurts to brush their teeth
Immediately look for areas where there are no local factors and look for
inflammation there
o To check the possibility of systemic factors causing local
gingivitis
What is this clinical presentation?

Pemphigus vulgaris
Combination of PV
inflammation and
gingival inflammation
accumulating local
factors can result in
advanced loss of
attachment and tooth
loss
Pemphigus vulgaris
Etiology
Pemphigus vulgaris is not fully understood.
Experts believe that it’s triggered when a person who has a genetic tendency to get this condition comes into contact with an environmental trigger, such as a chemical or a drug.
In some cases, pemphigus vulgaris will go away once the trigger is removed.
Pemphigus vulgaris
Treatment
Treatment has 3 stages:
● Stage 1: Control
○ Suppress inflammation / lesion activity with Systemic Corticosteroid: Remains initial / 1st‐line treatment…
○ Then quickly add steroid‐sparing agents (mycophenolate mofetil) to minimize dose and duration of corticosteroid treatment as well as improve disease control
● Stage 2: Consolidation
○ Reducing auto‐antibody production with the addition of Immunosuppressants
○ Assessed by the lack of development of NEW lesions
● Stage 3. Remission / Maintenance:
○ achieving complete remission of lesion activity OFF medication is the GOAL
○ When lesion activity OFF medications cannot be achieved, principle of MINIMALLY effective therapy is the goal, typically with combination of immunosuppressant medications
○ RITUXIMAB has become the FIRST CHOICE treatment after
○ the consolidation phase to achieve DISEASE REMISSION
● TOPICAL / INJECTABLE CORTICOSTEROID MEDICATIONS
○ o Can be used to help control limited number of lesions resistant to systemic therapy: it treats ONLY the disease
○ outcome (lesions) and not the systemic illness / pathologic antibody production
○ ex:clobetesol 0. 05% , halbetesol 0.05% (most potent)

REMEMBER:
▪ Plaque and calculus can be the consequence of painful MMP lesions
▪ When assessing MMP lesions/desquamative gingivitis, look for areas of intense inflammation WITHOUT local factors as evidence of VB disease
Mucous membrane pemphigoid
Etiology
Mucocutaneous autoimmune disease characterized by sub‐epithelial
blisters (bullae) which ruptures to form large, non‐healing ulcerations
Mucous membrane pemphigoid
Treatment
o Approach is similar to PV – but generally not as aggressive unless
hi‐risk areas ( ocular, esophageal ) where more intense immunosuppression indicated
▪ NON‐immunosuppressive treatments uniquely effective:
- *o** Dapsone
- *o Tetracycline + nicotinamide**
MMP & PV BIOPSY
take two different sites
○ For H&E, still must be perilesional
○ If you get only ulcer just because the clinician thinks
○ that is the pathology → there is no epithelium!
○ The sample is useless and no diagnosis can be made

squamous cell carcinoma
Risk factors
HPV + SCC
Area affected: ( Oropharynx cancers largely involved tonsils, . Posterior 3rd of the Tongue)
Younger pts, 3:1 Males to females ratio, high socio-eco status
Incidence is decreasing
less aggressive → higher survival rates ( Better than HPV negative SCC)
HPV - SCC
The chief risk factors for oral squamous cell carcinoma are
Smoking (especially > 2 packs/day)
Alcohol use
Risk increases dramatically when alcohol use exceeds 6 oz of distilled liquor, 15 oz of wine, or 36 oz of beer/day. The combination of heavy smoking and alcohol abuse is estimated to raise the risk 100-fold in women and 38-fold in men.
( this affects these ares : the tongue, floor of mouth, buccal mucosa, or gingiva)
mostly men, low socio-economic factors
Incidence is decreasing
Very aggressive → lower survival rates
SCC treatment
Early stage: Radiation and/or Surgical removal
Late stage : combination of surgery, radiation therapy, or chemotherapy

Treatment
No Treatment Needed
but we need to biopsy to rule out other diseases
What is this clinical finding?

Frictional Keratosis.
There is a rough, hyperkeratotic change to the posterior mandibular alveolar ridge (“alveolar ridge keratosis”),
because this area is now edentulous and becomes traumatized
from mastication.
Such frictional keratoses should resolve when the
source of irritation is eliminated and should not be mistaken for true
leukoplakia.

What is this clinical finding?
Xerostomia-related Caries
Or
Dry Mouth
. Extensive cervical caries of
mandibular dentition secondary to radiation-related xerostomia.
Dry mouth
Subjective vs Objective
Xerostomia
The subjective experience of a dry mouth (ie a symptom)
Salivary Hypofunction
The objective measurement of a reduction in salivary flow (a sign)
What is the normal rate for Stimulated Saliva
Production
Stimulated Saliva
Production
▪ 200+ ml/day
▪ Flow rate: mean 1-2 ml/min, maximum 7 ml/min
o “Normal” range is very wide
What is the normal rate for Unstimulated Saliva
Production
300 ml/day
▪ Flow rate: mean 0.3 ml/min
What are Factors affecting unstimulated flow include?
- Dehydration
- Medical conditions
- Body posture
- Lighting conditions
- Circadian/circannual rhythm (lowest during)
- Medications
Age is an independent factor for whole saliva andsubmandibular/sublingual gland secretion (but notparotid).
What are Factors affecting stimulated flow include:
- Mechanical stimuli
- Vomiting
- Gustatory/olfactory stimuli (acid/smell)
- Gland size
Age is an independent factor for whole saliva (but not
for parotid and minor gland secretions)
What causes
dry mouth?
Central inhibition as a result of connections between the primary salivary centers and the
higher centers of the brain.
● What causes xerostomia in absence of measurable salivary hypofunction?
-
May be a reduction in baseline sialometry which is still above “normal.”
- If they get a decrease in the salivary flow, they still may be in the normal range, but for them the experience is that they have got dry mouth.
-
Saliva film thickness
- Palatal mucous gland secretions?
- Anterior dorsum of tongue?
-
Relative contributions by glands
- Mucins, proteins?
- Alterations in sensory perception?
- Mental status/central inhibition?
What cause
Salivary
Hypofunction?
● Dehydration
● Medications (Rx & OTC)
- Direct damage to glands
- Head and neck radiotherapy
- As a result of radiation it’s irreversible damage to the glands
- Chemotherapy (reversible)
- Autoimmune diseases
- Primary vs Secondary Sjögren’s Syndrome, GVHD
- HIV disease
● Decreased mastication (tooth loss, soft diet)
● Conditions affecting the CNS:
- Psychologic disorders (depression/anxiety?), Alzheimer’s, Parkinson’s, Cerebral palsy
To have dry mouth
xerostomia
what is the rate of Unstimulated and Stimulated Salivary flow
USFR
and
SFR
Abnormal unstimulated USFR= <0.1–0.2ml/min
Abnormal stiumated SFR = <0.5ml/min
Severity of patients
with xerostomia using
objective measures

How to manage with normal USFR and SFR?
- Salivary stimulation (OTC) to stimulate their glands
- Salivary lubrication ( to improve it)
- Humidification ( like a humidifier in the room at night)
- Hydration/prevent dehydration (ie avoid alcohol, caffeine both will act as a
- diuretic and lead to dehydration).
- Monitor closely to rule out emerging disease ( to see whether they are developing Sjogren’s or something else we want to follow them over time)
How to manage with abnormal USFR and normal SFR?
(respond to stimulated)
Abnormal unstimulated USFR= <0.1–0.2ml/min
- Look for possible causes (major cause will be medications & can dehydration or others)
- Restore chewing function (Masticatory issues)
- Reduce medication‐induced salivary hypofunction
- Prescribe Salivary stimulation OTC, Rx medications, others
- Prescribe Salivary lubrication
- Humidification ‐use humidifiers
- Hydration/prevent dehydration (ie avoid alcohol, caffeine)
- Treat oral consequences (such as candidiasis treated with an antifungal or caries with management of caries).
How to manage with abnormal USFR and abnormal SFR?
Abnormal unstimulated USFR= <0.1–0.2ml/min
Abnormal stiumated SFR = <0.5ml/min
- If dehydrated ► rehydrate or treat underlying condition
- People with uncontrolled diabetes, once you control the diabetes‐ their flow comes back.
- All we can do is offering Salivary substitutes (sprays, gels, rinses )
- For patients with high dose radiation treatment ► makes sure they get the INRT
- Minimizing damage to salivary glands ( there are other strategies for that)
- Prevention and treatment of oral complications
What are the
Prescription
Medications
for people with
low USFR and
some oral signs, but
responds to stimulation ?
(abnormal USFR, Normal/improved SFR)
(include dosage and usage)
– Muscarinic agonists:
– Pilocarpine 5‐7.5mg tid & qhs (can go as
high as 10mg qid)
– Cevimeline 30mg tid (can go as high as
60mg tid)
Contradicated for : CV disease, hepatic, renal or respiratory diseases or narrow angle glaucoma
Pilocarpine affects M1 & M3
side effects (sweating, flushing,
rhinitis, increased urination, weakness and
some experience the shakes. )
Cevimeline affects M3 only
fewer side effects
