Questions and Answers

Which statement correctly differentiates between xerostomia and hyposalivation?

Both xerostomia and hyposalivation are purely objective measurements of oral dryness.

Xerostomia indicates reduced salivary flow, while hyposalivation indicates normal salivary secretion.

Xerostomia is an objective finding, while hyposalivation is a subjective symptom.

Hyposalivation is defined by diminished salivary secretion, while xerostomia refers to a patient's subjective feeling of dry mouth. (correct)

What is the most common cause of salivary gland hypofunction in the elderly population?

Aging itself

Polydrugs taking (correct)

Dietary deficiencies

Poor oral hygiene

What role does saliva play in maintaining oral and general health?

Promotes hair growth and bodily hydration

Facilitates weight loss through metabolic functions

Study Notes

Salivary Gland Diseases and Dysfunction

Diagnosis of salivary gland diseases and dysfunction is crucial.
The date of the presentation was November 4, 2024.
The presenter was Shin-Mey R. Y. Geist, DDS, MS, FDS RCSEd, a Diplomat of the American Board of Oral Medicine, and Associate Professor.

ICD-10-CM Codes

K11 Diseases of salivary glands is a broad category.
Specific ICD-10-CM codes further categorize various ailments of salivary glands.
The codes cover atrophy, hypertrophy, sialoadenitis (acute, chronic, and recurrent), abscesses, fistulas, sialolithiasis (salivary stones), mucoceles, salivary secretion disturbances, and unspecified conditions.

ADA's CDT 2024 Selected Codes

K11.0 covers atrophy of the salivary gland.
A variety of other codes deal with different salivary gland conditions.
The codes are selected from the ADA's CDT 2024 to highlight important conditions.

Learning Objectives

Be able to diagnose salivary gland diseases using previous coursework on Oral Pathology.
Understand the difference between resting and stimulated saliva and their contributing factors.
Properly use the terminology "xerostomia" and "hyposalivation," differentiating subjective and objective measures.
Recognize and identify risk factors for hyposalivation.
Identify clinical (physical) signs of hyposalivation.
Describe the diagnostic approaches for hyposalivation, including methods and laboratory criteria.
Understand the significance and complications of hyposalivation.

Anatomy of the Salivary Glands

Diagrams show the parotid, submandibular, and sublingual salivary glands, and associated ducts.
Diagrams depict the locations of these glands with respect to surrounding facial structures.

Normal Submental Evaluation

Ultrasound images illustrate normal anatomy of certain salivary glands and surrounding structures.
Images show normal submental structures.

Ranula, Purulent Drainage, and Mucoceles

Ranula is a type of mucocele occurring on the floor of the mouth.
Purulent drainage can be associated with acute suppurative sialadenitis of the submandibular duct.
Mucoceles arise from intraductal or extraductal mucus extravasation.

Salivary Glands and Saliva

Three major salivary glands produce approximately 90% of saliva.
Smaller minor salivary glands contribute the remaining 10%.
Saliva is predominantly water (99%) with 1% proteins and electrolytes.

Saliva

Daily saliva production in healthy individuals is between 0.5 and 1.5 liters.
Submandibular glands are the major contributors to resting saliva (65-70%), while parotid glands are more important for stimulated saliva.
Insufficient stimulated saliva negatively affects various oral functions.

Hyposalivation

Saliva plays crucial roles in oral and general health, preventing caries, assisting swallowing, and maintaining oral hygiene.
Many medical conditions and medicines can affect salivary production.
Hyposalivation in the elderly deserves assessment for factors beyond normal aging.
More than 400 medications can cause oral dryness and reduced salivary flow; many categories are implicated.
Hypertension medications raise the risk of oral dryness.

Information Needed for Hyposalivation Diagnosis

Thorough patient history is essential.
Relevant medical conditions and medication history must be assessed.
Observe oral health signs, including mouth mirror stickiness, atrophic mucosa, and salivary flow.
Quantitative measurement of saliva is a vital clinical and lab test.
Specific salivary flow criteria are required for diagnosis.

Complications of Hyposalivation

Hyposalivation causes oral dryness, chewing difficulties, swallowing problems, speech alteration, denture discomfort, dental caries, oral candidiasis, and miscellaneous issues.

Dental Decay and Hyposalivation

Dental decay is a serious complication of hyposalivation.
Hyposalivation considerably increases dental decay risk.

References

Various citations provide evidence-based support for the information presented.
Articles discuss methodologies and medical conditions relevant to diagnosing and managing hyposalivation and associated complications.

Case Studies

Case studies provide specific practical application of the information, demonstrating clinical and radiological findings, and insights into diagnosis.

Why is Medical History Important for Dental Care?

Gathering patient medical history is crucial, particularly regarding conditions that may affect saliva or denture fit. Questions include any diseases and medication that could cause saliva reduction, especially for dentures.

Sjögren's Syndrome

Evidence suggests the presence of Sjögren's syndrome is observable in ultrasound images of the parotid glands and the structure appears inhomogeneous.
