Dry Mouth/ Xerostomia
Introduction
This is significantly a patient perception.
Dry mouth & Oral dryness are general terms that encompasses 2 medical entities
- Xerostomia (This is a symptom) – subjective complaints
- Hyposalivation – Objective reduction in salivary secretion
Mainly occur due to decreased salivary flow or decrease composition of the saliva.
& there are many of other causes.
So this is a subjective clinical condition due to absolute or relative reduction in amount of saliva
Advancing of the age also increasingly associated with the dry mouth. But this is usually due to
medications & diseases.
Causes
Causes
Iatrogenic
1.Drugs
-Atropine
-Antidepressants : Tricyclic(eg:
Amitriptyline, Nortriptyline),
Selective serotonin reuptake
inhibitors
-Antihypertensive : Can also cause
the compositional changes of the
saliva as well as the changes of the
flow rate.
- Antihistamines
- Opioids
- Cytotoxic drugs
-Antiemetics
2.Irradiation(External irradiation
doses above 40 Gy & Iodine 131)

patient can be
classified in to
3 types
Those having
asymptomatic
hyposalivation,ie reduction
in the salivary secretion
not significant enough to
cause xerostomia.
Those with
symptomatically significant
hyposalivation, thus
suffering from xerostomia.
Those suffering from
xerostomia but with no
evident decrease in salivary
secretion
5. Thilanka Umesh Sugathadasa Page 4
Diagnosis & Ix
Diagnosis is mainly by the combination of the
- Hx
- Ix
- Clinical features.
Investigations
Salivary function studies
1. Salivary flow rate
2. Sialography
3. Salivary scintiscanning
Other
1. Lacrimation flow – exclude sjogren's syndrome
2. Urinanalysis – exclude DM
3. Blood tests
ESR – exclude Sjorgren’s syndrome or sarcoidosis
antinuclear antibodies – exclude Sjorgren’s syndrome or sarcoidosis.
Rheumatoid factor – Exclude Sjorgren’s syndrome
Serology – Viral disease
Serum calcium & phosphate – exclude hyperparathyroidism.
4. Imaging
CXR –exclude Sarcoidosis
Ultrasonography – exclude Sjorgren’s syndrome or Neoplasia
MRI –exclude Sjorgren’s syndrome
5. Bx
Biopsy is taken if there is a suspicion about the organic disease of the salivary glands. Here
always possible to take biopsy from the major salivary glands but usually perform the minor SG
Bx due to risks of nerve damage, scars. So usually preferable site is the lower labial mucosa.
Management
Can divide in to 3 categories
1. Symptomatic Rx
2. Preventive Rx
3. Curative Rx
Salivary flow over a 24-hour period
Sleep
40 ml saliva will be produced over 7 hours
Awake
300 ml of unstimulated saliva over 16 hours
200 ml of stimulated saliva during meals over 54 minutes
6. Thilanka Umesh Sugathadasa Page 5
Symptomatic Rx Preventive Rx Curative Rx
(- Directed at alleviating or minimizing complaints associated
with decreased salivation. Range from simple methods of
hydration & lubrication to systemic secretagogues to stimulate
the salivary function)
Non sugar containing fluids & frequent small
sips of them. Helps to hydrate the mucosa &
removal of retained debris
Avoids fluids containing sugars.
Humidifiers specially closer to bed at night
(Can use jug of water)
Lip moisturizers & emollients.
Penetrating creams are preferred over the
petroleum based products.
Avoid dry foods.
Avoiding spicy foods, alcohol & strong
flavoring may reduce oral mucosal sensitivity.
Avoid mouth rinses with high alcohol content.
(Listerine), which can induce mucosal
irritation & sensitivity.
Mechanical, local saliva induce with sugarless
candy, gums or rinses.
disadvantages of local stimulants
- short lived
- Frequent application can be inconvenient.
- Citric acid may irritate the oral mucosa.
- continue use may contribute to
demineralization.
Systemic sialologues
- Only use for the patients who have salivary
tissues that can be stimulated.
- Pilorcarpine hydrochloride-
parasympathomimetic agonist that increase
exocrine output.
- Most widely tested sialagogue.
- Recommended dose = 5mg tds
- Cevimeline hydrochloride – similar to
Pilorcarpine. (This product can’t use in high in
high conc as it containing metals.)
Salivary replacement products (Substitute)
commonly containing Carboxymethylcellulose
or hydroxycellulose as lubricants, artificial
sweeteners, preservatives, chloride &
Fluorides
(- To limit the consequences of
salivary gland hypofunction on oral
& dental tissues)
Increase oral hygiene
measures.
Professional care.
Oral application of topical
fluorides to minimize the
dental caries risk.
If bacterial infection is
identified, appropriate
antibiotics should be
identified. It may require
prolonged therapy.
If swelling which is not
due to infection a short
course of steroids are
beneficial.
NSAIDs are not helpful
If candidal infection
presents use topical or
systemic antifungals
prolongly
those antifungals should
not contain sugars.
Composition of the
artificial saliva
- Carboxymethylcellulose
10g/L(Keep the watery
content of saliva)
- Sorbitol 30mg/L
- Sodium chloride
- Magnesium chloride
- Calcium chloride
- Dipotasium hydrogen
phosphate
Disadvantages
- Regular use is
inconvenient.
- More viscous than the
natural saliva so feel odd.
- Expensive
- No antimicrobial & other
protective functions.
(Managing underlying cause
or symptoms)
If dry mouth is due
to drugs,
stopping/changing
drugs if possible, in
consultation with
patient’s physician.
If possible
alternative drug.
Identify the cause
by history,
examination &
further
investigations & Rx
- Secretagogues can
provide transient
relief but will not
address the
underlying cause.
- Patients may leave
with gradual
decline in function
over time &
worsening the
symptoms & signs.

12. Thilanka Umesh Sugathadasa Page 11
For the diagnosis of primary SS:
In patients without any potentially associated disease, primary SS may be defined as follows:
The presence of any 4 of the 6 items is indicative of primary SS, as long as either item IV
(histopathology) or VI (serology) is positive
The presence of any 3 of the 4 objective criteria items (that, is items III, IV, V, VI)
The classification tree procedure represents a valid alternative method of classification,
although it should be more properly used in clinical “epidemiological survey
For the diagnosis of secondary SS:
In patients with a potentially associated disease (for instance, another well-defined connective
tissue disease), the presence of item I or item II plus any 2 from among items III, IV, and V may
be considered as indicative of secondary SS
Exclusion criteria:
1. Past head and neck radiation treatment
2. Hepatitis C infection
3. Acquired immunodeficiency disease (AIDS)
4. Pre-existing lymphoma
5. Sarcoidosis

Obstructive disorders
Condition Features & etiology Clinical features/ Ix & Diagnosis
Sialolithiasis(S
alivary gland
calculi or
stones)
Calculi composed of
laminated layers of
organic materials covered
with concentric shells of
calcified materials.
Mainly hydroxyapatite
crystals containing
octacalcium phosphate.
Etiology & pathogenesis
Nuerohumoral
mechanisms
Metabolic
mechanisms(eg: presence
of existing inflammation)
Common in the
submandibular
glands(80%)
10% in the parotid gland.
Reasons for higher
prevalence of sialoliths in
the SMG
Physiological factors
- Saliva more alkaline
- Presence higher conc of
Calcium & Phosphate
- Higher mucus content
- Richness in phosphatase
enzyme.
- Low content of Co2
Anatomical factors
- Longer duct
- anti gravity flow(position
of the gland)
- Smaller orifice than the
ductal luman.
- Irregular course of duct.
Middle aged people with slight male predilection
Size can vary from few mm to several cm.
Intraglandular sialoliths cause less problems to the
patients than extraglandular/ ductal sialoliths.
Symptoms
- Sometimes there are no any symptoms
- Meal time swelling (due to increase demands)
- Moderate pain(due to increase pressure)
- fever & malaise due to infections (If untreated)
Signs
- Pus discharge through the orifice
- Severe inflammation in the soft tissues.
- Overlying mucosa may be ulcerated.
- Sialoliths may be palpated if it presents in the
extraglandular portion.
- Reduce salivary flow
- Enlargement of the glands.
Radiological features
- Radiolucent calculi(Here 80-90% of SMG calculi are
radio-opaque & 50-80% of parotid calculi are
radiolucent.)
- Solitary or Multiple(30% of the SMG stones are
multiple & 60% of the parotid stones are multiple)
- Usually oval shape & is cylindrical with multiple layers
of calcifications.
Sialography is indicated when sialoliths are radiolucent,
Here we can see easily the ductal dilatation & the
sialodochitis.
Radiological DD
- Hyoid bone
- Myositis ossificans
- Phleboliths
- Calcific submandibular lymph nodes
- Gas bubble in sialography

5. Infections
6. Temporary parasthesia
7. Bleeding
8. Ranula formation
Interventional radiology
Various techniques are using
- coronary angioplasty
balloon
- Wire loop
- Embolectomy catheter
Under fluoroscopy guidance
Best method is the
fluoroscopically guided stone
retrieval (success rate 40-100%)
Main complications are
Gland swelling
Infections
Main limitation is the
administration of ionizing
radiation.
Antibiotics if acute infection is present
Increase salivation & allow stone to come out through
orifice.
Manual manipulation(milking)
E/O & I/O palpation behind the calculi in to the orifice.
Lithotripsy(shock wave)- sialolithotripsy
- Introduced in 1989
- Noninvasive method of fragmenting the stones in to
smaller portions to allow possible flushing out
spontaneously.
- stone fracture by producing a compressive wave that
spread through calculus & expansive wave that pit stone &
induce cavitations
- shock wave can be generated
Extra-corporeally using piezoelectric or
electromagnetic techniques
Intra-corporeally using electro-hydrolic, pneumatic or
laser endoscopic techniques
Sialoendoscopy
- First used to diagnosis but now also used for the calculi
removal.
- First describe in 1991
- Rigid, semi rigid, or moderately flexible endoscopes
presents with different diametres.
- Equipped with working channels & irrigation ports
- Main problem is the entering through orifice
- this problems are overcome by
Dilatation with lacrimal probes/ guiding wires
Papillotomy with CO2 laser
Microsurgical dissection of anterior duct(ductal cut
down)
Graspers, miniforceps, dormaia baskets & balloons to
remove stone
- Not indicated if the calculi is located deeply inside the
gland or embedded in wall.
- Success rate is around 89% for submandibular & 83-86%
for parotid calculi
- Also effective in removing mucus plugs, foreign bodies,
polyps & granulation tissue.
- Contraindicated if there is complete distal obliteration of
duct.
- insertion of the sialostent averts recurrences

particularly if inappropriate antibiotics are
used, or predisposing factors not eliminated.
Serous acini atrophy when salivary outflow is
chronically obstructed, further reducing saliva
secretion.
Usually caused by streptococcus viridans

- Salivary gland swelling
- Facial palsy
Mumps
This is the most commonest & important
condition.
Acute contagious viral infection
Characterized by bilateral/ unilateral gland
enlargement.
Mainly affects the major salivary glands but
also can affects testis, meninges, pancreas,
heart & mammary glands.
Also called endemic parotitis
Caused by paramyxovirus
Endemic in most urban population
Airborne infection
Clinical features
- more common in boys & often between 5-15
years of age.
- Incubation period is 2-3 weeks
- Prodromal symptoms(Onset of headache,
chills, moderate fever, vomiting, pain below
ear & last about 1 week)
- Parotids are usually affected & mostly
bilateral.
- SMG is less commonly involved & when
affected have less swelling & pain.
Symptoms – Prodromal symptoms followed by
sudden onset of painful salivary gland swelling
without purulent discharge from duct.
Signs- Elevation of ear lobe, Firm/ rubbery/
elastic gland enlargement., Puffy & reddened
papilla.
No antiviral therapy or
antibiotics advocated.
Bed rest & isolation
Hydration with plenty of
fluid intake.
NSAIDs(ibuprofen)
for children’s: Ibuprofen
syrup 100mg/5ml

Asymptomatic
enlargement
(Sialosis/
Sialadenosis)
Non- neoplastic, non- inflammatory enlargement of the salivary glands
Usually bilateral & may presents as recurrent painless enlargements.
Commonly in parotids in males.
Associated with systemic conditions such as cirrhosis, diabetes, thyroid
insufficiency, alcoholism & malnutrition
Alteration occurs in the chemical composition of saliva.
Significant elevation of salivary potassium & decrease in sodium.
Sialorrhea
(Ptyalism)
Increase salivary secretions occurs.
2 types
- True Sialorrhea: Rare, may be due to rabies,
metal poisoning, inflammatory lesion in the
mouth
- Pseudo Sialorrhea: Common in
infants(drooling), Neuromuscular problems,
Down’s syndrome, paralysis, Mental handicaps
Etiology
- Drugs
- Local factors such as stomatitis, erythema
multeforme & ANUG
- Systemic disease such as rabies, paralysis,
alcoholic neuritis, epilepsy, Down’s syndrome,
Neuromuscular disorder
- Miscellaneous causes such as psychic
factors, metal poisoning & facial paralysis
Clinical features
- Excessive production or inadequate
swallowing due to neuromuscular in-
coordination.
- Affected individuals may need several cloths
- Emotional & physical impairment.
- Infections due to chronic exposure to saliva
- Ulceration & cheek scarring due to recurrent
infections & necrosis of tissues.
Botulinum toxin injection is
an effective method
Cause selective chemical
denervation by blocking
neurotransmitter release at
the cholinergic
parasympathetic nerve
terminals of the salivary
glands. So secretory
capacity of the gland is
reduced.
Botulinum toxin therapy is
also used to treat sialocele
& chronic & recurrent
parotitis.
Diseases of minor salivary
glands
Mucocele
Nicotinic Stomatitis
Necrotizing
sialometaplasia
Neoplasms
